The name of the database where new users get added in MariaDB is not specified in the question.
In MariaDB, new users are typically added to a specific database known as the "mysql" database. This database is created automatically during the installation process and is used to store system-level information, including user accounts and access privileges.
When interacting with the MariaDB server through the command-line interface, the command "mysql" is used to establish a connection to the server. The "-D" option is used to specify the database to connect to, followed by the name of the database. For example, to connect to the "mysql" database, the command would be:
$ mysql -D mysql -e "SELECT * FROM user"
In this command, the "-e" option is used to execute the SQL query specified within the quotes. In this case, the query is retrieving all the rows from the "user" table within the "mysql" database.
It's important to note that while the "mysql" database is commonly used for managing user accounts, it is also possible to create additional databases in MariaDB and assign privileges to users accordingly.

5.1 LAB: Output values below an amount Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain less than 20 integers. Ex: If the input is: 5 50 60 140 200 75 100 the output is: 50, 60, 75, The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a comma, including the last one. Such functionality is common on sites like Amazon, where a user can filter results. 396190.2640062.qx3zqy7 LAB 5.1.1: LAB: Output values below an amount 0/10 ACTIVITY main.c Load default template... const int NUM_ELEMENTS = 20; int userValues [NUM_ELEMENTS]; // Set of data specified by the user /* Tune your code here */ 1 #include 2 3 int main(void) { 4 5 6 7
This program takes a list of integers as input, with the first number indicating the number of integers in the list. It then outputs all integers in the list that are less than or equal to a specified threshold.
The program starts by declaring a constant variable NUM_ELEMENTS with a value of 20, which represents the maximum number of integers that can be entered. It also defines an integer array userValues to store the input integers.
The program then includes the necessary header file stdio.h for input and output operations.
In the main function, the program initializes variables and prompts the user for input. It uses a loop to read the integers into the userValues array, based on the first number entered by the user, which indicates the number of integers to follow.
After reading the input, the program retrieves the last value from the array, which represents the threshold. It compares this threshold value with each integer in the array and outputs the integers that are less than or equal to the threshold, separated by commas. The output follows the format commonly seen on e-commerce websites like Amazon, where results can be filtered.
The program ends by returning 0, indicating successful execution.

Consider the regular and context-free languages. Since both
categories can
represent infinite languages, in what sense is one category broader
(more
expressive) than the other?
Context-free languages are considered to be a broader category than regular languages in terms of the types of languages they can represent.
The main difference between regular and context-free languages is in the types of grammars that generate them. Regular languages are generated by regular grammars or finite automata, while context-free languages are generated by context-free grammars.
In terms of expressive power, context-free languages are generally considered to be more expressive than regular languages because they can represent a wider range of languages. This is because context-free grammars have more generative power than regular grammars. For example, context-free grammars can handle nesting, which means that they can generate languages that involve matching brackets or parentheses, such as balanced parentheses languages. In contrast, regular grammars cannot handle this kind of nesting.
Another way to think about this is that context-free grammars allow for the use of recursive rules, which enable the generation of infinitely many strings with complex nested structures. On the other hand, regular grammars do not allow recursion and can only generate a limited set of patterns.
Therefore, context-free languages are considered to be a broader category than regular languages in terms of the types of languages they can represent.

Equivalent of Finite Automata and Regular Expressions.
Construct an equivalent e-NFA from the following regular expression: 11 + 0* + 1*0
To construct an equivalent ε-NFA (epsilon-Nondeterministic Finite Automaton) from the given regular expression `11 + 0* + 1*0`, we can follow these steps:
Step 1: Convert the regular expression to an NFA
The regular expression `11 + 0* + 1*0` consists of three parts connected with the `+` operator:
1. `11`: This part matches the string "11".
2. `0*`: This part matches any number of occurrences of the character "0".
3. `1*0`: This part matches any number of occurrences of the character "1", followed by a single "0".
To construct the NFA, we'll start by creating separate NFAs for each part and then connect them.
NFA for `11`:
```
Initial state --(1, ε)-->-- 1 --(1, ε)-->-- Final state
```
NFA for `0*`:
```
Initial state --(0, ε)-->-- Final state
|
--(ε, ε)-->-- Initial state
```
NFA for `1*0`:
```
Initial state --(1, ε)-->-- 2 --(0, ε)-->-- Final state
| |
--(ε, ε)-->-- 3 --
```
Step 2: Connect the NFAs
We'll connect the NFAs by adding ε-transitions from the final state of one NFA to the initial state of the next NFA.
```
Final state of `11` --(ε, ε)-->-- Initial state of `0*`
Final state of `0*` --(ε, ε)-->-- Initial state of `1*0`
```
Step 3: Add the final state
We'll add a new final state and make all the previous final states non-final.
```
Final state of `11` --(ε, ε)-->-- Initial state of `0*` --(ε, ε)-->-- Final state
Final state of `0*` --(ε, ε)-->-- Initial state of `1*0` --(ε, ε)-->-- Final state
```
Step 4: Combine all states and transitions
We'll combine all the states and transitions from the previous steps into a single ε-NFA.
```
Initial state --(1, ε)-->-- 1 --(1, ε)-->-- Final state
|
--(ε, ε)-->-- Initial state --(0, ε)-->-- Final state
|
Final state --(ε, ε)-->-- Initial state --(1, ε)-->-- 2 --(0, ε)-->-- Final state
| |
--(ε, ε)-->-- 3 --
```
This is the final ε-NFA that represents the given regular expression `11 + 0* + 1*0`.

An isogram is a word in which the letters occur an equal number of times. The following are examples: - first-order isogram (each letter appears once) : byzantine
- second-order isogram (each letter appears twice) : reappear
- third-order isogram (each-letter appears three times) : deeded
A phrase's isogram score is calculated as the sum of each word's score divided by the length of the words in the phrase and rounded to the nearest one hundredth. A word's score is 0 if the word is not an isogram; otherwise, it is computed by multiplying the isogram order level by the length of the word. Isogram scoring should treat words case-insensitively. Calculate the isogram score for the given input phrase. Input Format Input phrase is a string that will only be comprised of letters and spaces. Words will be separated by a single space. (Read from STDIN) Constraints Characters in input string include: - A−Z - a−z - space Output Format Output is a decimal number rounded off to the nearest one hundredth. (Write to STDOUT) Sample Input 0 Vivienne dined àt noon Sample Output 0 1.37 Explanation 0 round (((2∗8)+0+(1∗2)+(2∗4))/19,2)=⇒round(26/19,2)=⇒round(1.368421…,2)
The isogram score for a given input phrase is calculated by determining the isogram order level for each word, multiplying it by the length of the word, and summing up these scores. The total score is then divided by the length of the words in the phrase and rounded to the nearest one hundredth. The isogram order level corresponds to the number of times each letter appears in a word. The calculation is performed case-insensitively, treating words in the phrase as separate entities. The output is a decimal number representing the isogram score.
Explanation:
To calculate the isogram score for the given input phrase "Vivienne dined àt noon", we follow these steps:
1. Split the phrase into words: ["Vivienne", "dined", "àt", "noon"].
2. Calculate the score for each word:
- "Vivienne": Isogram order level is 2 (each letter appears twice), and the length of the word is 8. So the score is 2 * 8 = 16.
- "dined": Isogram order level is 0 (not an isogram), so the score is 0.
- "àt": Isogram order level is 1 (each letter appears once), and the length of the word is 2. So the score is 1 * 2 = 2.
- "noon": Isogram order level is 2 (each letter appears twice), and the length of the word is 4. So the score is 2 * 4 = 8.
3. Sum up the scores: 16 + 0 + 2 + 8 = 26.
4. Calculate the isogram score: 26 / 19 (total length of words in the phrase) = 1.36842105.
5. Round the score to the nearest one hundredth: 1.37.
Therefore, the isogram score for the input phrase "Vivienne dined àt noon" is 1.37.

By using 3 prime numbers, we can also define RSA cryptostem where N=pqr. Again we must have gcd(e,ϕ(N))=1 and d is the multiplicative inverse of e in modulo ϕ(N). (b) Why this 3-prime RSA is not preferred?
The 3-prime RSA is not preferred due to weaker security, increased complexity, longer key lengths, and lack of standardization compared to the 2-prime RSA.
The 3-prime RSA, where the modulus N is defined as N = pqr using three prime numbers (p, q, and r), is not preferred for several reasons:
Security: The security of RSA is based on the difficulty of factoring large composite numbers into their prime factors. In the case of 3-prime RSA, the factorization becomes easier since the modulus N has only three prime factors. This makes it more vulnerable to attacks such as the General Number Field Sieve (GNFS) algorithm, which is a powerful method for factoring large numbers.
Complexity: The use of three prime numbers increases the complexity of the RSA algorithm. The computations involved in key generation, encryption, and decryption become more intricate, leading to higher computational costs and slower operations compared to the standard 2-prime RSA.
Key Length: To achieve a similar level of security compared to 2-prime RSA, the key length for 3-prime RSA needs to be longer. This is because the prime factors of the modulus N are smaller in the 3-prime case, making it easier to factorize the modulus. Longer keys require more computational resources and may have practical limitations in terms of memory usage and performance.
Standardization: The RSA encryption algorithm is widely used and standardized, with well-defined protocols and implementations based on the 2-prime RSA. The use of 3-prime RSA introduces complexities and deviations from the established standards, making it less compatible and interoperable with existing RSA implementations.
Considering these factors, the 3-prime RSA is not preferred in practice due to its weaker security, increased complexity, longer key lengths, and lack of standardization. The 2-prime RSA remains the more widely adopted and recommended choice for RSA-based cryptographic systems.

In general terms (i.e., don’t talk about JavaScript here) describe in detail what steps you would take to generate the digital signature.
To generate a digital signature in general terms, you would typically follow these steps:
Create a message:
Hash the message
Prepare the private key
Sign the hash
Attach the signature
Verify the signature:
Create a message: The first step is to have the message or document that you want to sign. This could be a text document, an email, or any other digital data that requires authentication and integrity.
Hash the message: A cryptographic hash function is applied to the message to produce a fixed-length hash value. This step ensures that even a slight change in the message will result in a significantly different hash value. Commonly used hash functions include SHA-256 or SHA-3.
Prepare the private key: Digital signatures rely on public-key cryptography, which involves a key pair consisting of a private key and a corresponding public key. The private key is known only to the signer and is used for generating the signature. Ensure that you have access to the private key associated with your digital identity.
Sign the hash: The hash value obtained in step 2 is encrypted using the private key of the signer. This encryption process generates the digital signature. The algorithm used for encryption depends on the chosen cryptographic scheme, such as RSA or DSA.
Attach the signature: The digital signature is appended or associated with the original message. It may be stored as a separate file or embedded within the message itself, depending on the specific application or protocol being used.
Verify the signature: To verify the authenticity and integrity of the signed message, the recipient uses the corresponding public key. The recipient applies the same hash function as used in step 2 to the received message, then decrypts the digital signature using the public key. If the resulting hash value matches the decrypted signature, the message is considered valid and unchanged since the signature was generated.
It's important to note that the specific implementation of these steps may vary depending on the cryptographic algorithm, programming language, and framework being used. The above

12. Prove that n representation N is divisible by 3 if and only if the alternating sum of the bits is divisible by 3. The alternating sum of any sequence ao, a₁, ..., am is of n in binary o(-1) ¹a
We have shown that n representation N is divisible by 3 if and only if the alternating sum of the bits is divisible by 3.
To prove that the n representation N is divisible by 3 if and only if the alternating sum of the bits is divisible by 3, we need to show two things:
If N is divisible by 3, then the alternating sum of the bits is divisible by 3.
If the alternating sum of the bits is divisible by 3, then N is divisible by 3.
Let's prove each part separately:
If N is divisible by 3, then the alternating sum of the bits is divisible by 3:
Assume N is divisible by 3, which means N = 3k for some integer k. We can write N in binary representation as N = an2ⁿ + an-1 * 2ⁿ⁻¹ + ... + a₁ * 2 + a₀.
The alternating sum of the bits can be calculated as (-1)ⁿ * an + (-1)ⁿ⁻¹ * an-1 + ... + (-1)¹ * a₁ + (-1)⁰ * a₀.
Now, notice that (-1)ⁿ = 1 if n is even, and (-1)ⁿ = -1 if n is odd. Therefore, we can rewrite the alternating sum of the bits as (-1)⁰ * an + (-1)¹ * an-1 + ... + (-1)ⁿ * a₀.
Since N is divisible by 3, we have 3k = (-1)⁰ * an + (-1)¹ * an-1 + ... + (-1)ⁿ * a₀.
The right side of the equation is the alternating sum of the bits, and since 3k is divisible by 3, it follows that the alternating sum of the bits is divisible by 3.
If the alternating sum of the bits is divisible by 3, then N is divisible by 3:
Assume the alternating sum of the bits is divisible by 3, which means (-1)⁰ * an + (-1)¹ * an-1 + ... + (-1)ⁿ * a₀ = 3k for some integer k.
We want to show that N = an2ⁿ + an-1 * 2ⁿ⁻¹ + ... + a₁ * 2 + a₀ is divisible by 3.
Notice that (-1)⁰ * an + (-1)¹ * an-1 + ... + (-1)ⁿ * a₀ can be written as (-1)⁰ * an2ⁿ + (-1)¹ * an-1 * 2ⁿ⁻¹ + ... + (-1)ⁿ * a₀ * 2⁰.
This expression is equivalent to N, so we have N = 3k, which means N is divisible by 3.
Therefore, we have shown that n representation N is divisible by 3 if and only if the alternating sum of the bits is divisible by 3.

Write a program in Python that generates a random number between 1-100. The user is then asked to guess the number. If the guessed number is less than 10 numbers higher or lower, the program will display "Close". Otherwise, it will display "Keep trying". When the user guesses the number, the program will say "Correct" and displays the number of attempts. Lastly, the program will give the user the choice to either start again or quit.
Here's a Python program that generates a random number between 1-100 and allows the user to guess the number:
python
import random
def guessing_game():
num = random.randint(1, 100)
attempts = 0
while True:
guess = int(input("Guess a number between 1-100: "))
attempts += 1
if guess == num:
print(f"Correct! The number was {num}. It took you {attempts} attempts.")
play_again()
break
elif abs(guess - num) <= 10:
print("Close")
else:
print("Keep trying")
def play_again():
choice = input("Do you want to play again? (Y/N): ")
if choice.lower() == 'y':
guessing_game()
else:
print("Thanks for playing!")
guessing_game()
The guessing_game() function generates a random number between 1-100 using the random module's randint() function. It then prompts the user to guess the number using input() and checks if the guess is correct with an if statement.
If the guess is not correct, it checks if the guess is close (within 10 numbers higher or lower) by calculating the absolute difference between the guess and the actual number using the abs() function. If the guess is close, it prints "Close". If the guess is not close, it prints "Keep trying".
If the guess is correct, it prints "Correct!" along with the number of attempts it took to guess the number. It then calls the play_again() function which asks the user if they want to play again or quit.
The play_again() function takes the user's choice as input using input() and checks if the choice is 'Y' (yes). If the choice is yes, it calls the guessing_game() function again. If the choice is not yes, it prints "Thanks for playing!".

In chess, the knight is able to move two squares vertically and one square horizontally in any direction (forming the shape of an L). Write a program that will take in how many phone numbers a chess knight can dial x? Keep in mind that a phone pad is 3X4 and the knight can only stand on a numerical cell. So only, 10/12 keys the night can be stood on. Therefore, given an integer n, return the distinct phone numbers of length n that we can dial. Since, the knight can be placed on any numerical cell initially and then you should peform n-1 jumps to diala number length n. All jumps should be valid knight jumps
Given the phone pad is of size 3 x 4, the knight can stand on 10/12 keys.
Therefore, we need to find the distinct phone numbers of length n that can be dialed by the knight. Since the knight can be placed on any numerical cell initially and then we should perform n-1 jumps to dial a number of length n.The possible valid jumps are two steps vertically and one step horizontally, one step vertically, and two steps horizontally. For the problem, we can perform a depth-first search (DFS) and find all the possible phone numbers that can be dialed with a knight's valid moves in a chess game.
Here is the Python code for this: Python code:
In the above code, we have a dfs function that takes the current cell I and the number string as arguments. If the length of the number string is equal to n, we append it to the output array. If the length is less than n, we iterate over all the valid knight moves from the current cell and make recursive calls to the dfs function with the updated cell and number string. Finally, we call the dfs function for all the possible starting cells (i.e., 10 valid cells) and return the output array.

Question: Write A Method That Takes An Integer Array As Input. The Method Will Repeatedly Read A Value From The Array, Go To The Indicated Position, Read The Value At That Position, Then Go There, And So On Until A Limit Of 100 Is Reached Or The Index Is Out Of Bounds. The First Value Should Be Read From The Array At Index 0. The Method Must Return An Integer Count
Write a method that takes an integer array as input. The method will repeatedly read a value from the array, go to the indicated position, read the value at that position, then go there, and so on until a limit of 100 is reached or the index is out of bounds.
The first value should be read from the array at index 0.
The method must return an integer count of how many times it read a value from the array.
Here's an example.
INPUT: {1,3,0,5}
The method reads 1 from index 0
The method reads 3 from index 1
The method reads 5 from index 3
The method identifies that index 5 is out of bounds and returns 3 to indicate that 3 values were read from the array.
Here's another example:
INPUT: {4,-1,0,5,2,8,-2}
The method reads 4 from index 0
The method reads 2 from index 4
The method reads 0 from index 2
The method reads 4 from index 0
...
The method repeats up to a limit of 100 times and returns 100.
Here's another example:
INPUT: {3,-1,4,2,5,-2}
The method reads 3 from index 0
The method reads 2 from index 3
The method reads 4 from index 2
The method reads 5 from index 4
The method reads -2 from index 5
The method identifies that index -2 is out of bounds and returns 5 to indicate that 3 values were read from the array.

int[] example1 = {1, 3, 0, 5};
int x = countPops(example1);
System.out.println("Count is: " + x)

x = countPops(example2);
System.out.println("Count is: " + x);
int[] example3 = {3, -1, 4, 2, 5, -2};
x = countPops(example3);

break;
count++;
int nextIndex = arr[currentIndex];

```
The `countPops` method takes an integer array `arr` as input and implements the required logic. It iterates through the array, following the indicated positions until the limit of 100 is reached or an out-of-bounds index is encountered. It returns the count of how many times it read a value from the array.

SSD are made of NAND or NOR based memory arrays called flash memory NOR-based flash is more expensive than NAND-based? T or F
While NOR-based flash memory is not commonly used in SSDs, it has some advantages over NAND-based flash memory in certain applications due to its byte-addressable nature. However, NOR-based flash memory is typically more expensive than NAND-based flash memory due to its higher performance and lower density.
SSDs (solid-state drives) are made up of memory arrays that are based on flash memory technology. Flash memory is a type of non-volatile memory that can store data even when the power is turned off. There are two types of flash memory used in SSDs: NAND-based and NOR-based.
NAND-based flash memory is the most commonly used type of flash memory in SSDs. It is organized into blocks, and data is written and read in blocks, rather than individual bytes. NAND-based flash memory is less expensive than NOR-based flash memory because of its higher density and lower performance.
NOR-based flash memory is not commonly used in SSDs because of its higher cost and lower density compared to NAND-based flash memory. However, it has some advantages over NAND-based flash memory. NOR-based flash is byte addressable, which means that individual bytes can be read or written to directly. This makes it more suitable for use in embedded systems and other applications that require fast access to individual bytes of data.

Note: Keep in mind the answer is NOT 2^16/2 and is NOT 32768. The answer could be in percentage from 50%, 25%, 10%, 100%, or we can't tell.
The duty cycle set by the given code cannot be determined based on the information provided. It could be any value between 0% and 100%, depending on the specific implementation of the PWM module and the hardware configuration. Without additional details or documentation, it is not possible to determine the exact duty cycle set by the code.
The code initializes a Pulse Width Modulation (PWM) signal on pin 22 using the machine.PWM class. The duty cycle of a PWM signal represents the percentage of time the signal is high compared to its total period. In this case, the duty cycle is set using the `duty_u16()` method, which expects a 16-bit unsigned integer value.
However, the specific value passed to `duty_u16()` is not provided in the code snippet, making it impossible to determine the exact duty cycle.

Based on the response curves of the eye cones that sense colors, human eye is dramatically less sensitive in the range a) green b) red
c) yellow
d) blue
Based on the response curves of the eye cones that sense colors, the human eye is dramatically less sensitive in the range d) blue.
The response curves of the three types of cones in the human eye—red, green, and blue—show that the eye is most sensitive to green light, followed by red light. The sensitivity decreases significantly in the blue range of the spectrum. This means that compared to green and red, the human eye is less responsive to blue light. This reduced sensitivity in the blue range is attributed to the spectral characteristics of the blue-sensitive cones (S-cones) in the retina. Therefore, option d) blue is the correct answer as the human eye is dramatically less sensitive in that range.

Write a shell script that reads two numbers. The script should find if the summation of those two numbers is even or odd. Use the editor to format your answer
The shell script reads two numbers and determines whether their summation is even or odd.
Here is an example of a shell script that achieves the desired functionality:
```
#!/bin/bash
echo "Enter the first number: "
read num1
echo "Enter the second number: "
read num2
sum=$((num1 + num2))
if ((sum % 2 == 0)); then
echo "The sum of $num1 and $num2 is even."
else
echo "The sum of $num1 and $num2 is odd."
fi
```
In this script, the user is prompted to enter two numbers using the `read` command. The numbers are then added together and stored in the `sum` variable using the arithmetic expansion `$((...))`.
The script then checks if the remainder of `sum` divided by 2 is equal to 0 using the modulus operator `%`. If the condition is true, it means the sum is even, and a corresponding message is printed. Otherwise, if the condition is false, the sum is considered odd, and a different message is displayed.
This script allows for the determination of whether the summation of two numbers is even or odd in a simple and straightforward manner.

The expression x / y is evaluated first. Since both x and y are integers, integer division takes place. In this case, x / y evaluates to 0.
Next, we compare the result of x / y with 0. The comparison operator > has higher precedence than /, so x / y > 0 is equivalent to 0 > 0.
The result of the comparison in step 2 is false, since 0 is not greater than 0.
Finally, the ternary operator ? : is applied. Since the condition in step 3 is false, the value of the expression is the second operand of the operator, which is y.
Therefore, the value of z is set to 7.
It's worth noting that if x and y were floating-point numbers, the result of x / y would be a decimal value, and the condition (x / y > 0) might evaluate to true, depending on the values of x and y. In that case, the value of z would be x.

(1) Find the most recent five years historical financial statements (2017~2021) of your selected company (Note: for some companies, the most recent five fiscal years historical financial data is from 2018 ~ 2022)
(2) Use TREND function in Excel to perform linear trend extrapolation for the sales of the company from 2022 to 2026 (or 2023~2027).
(3) Perform regression analysis to analyze the relation of sales and inventory of the company. Interpret the regression results: coefficient, t-statistic for the coefficient, R square, R square adjusted, and F statistic.
(4) Use the percent of sales method to forecast the next year 2022 (or 2023) financial statements (Income Statement, Balance Sheet) of the company. (5) (Iteration calculations) Use iteration calculations in Excel to eliminate DFN in the pro forma balance sheet if DFN is not equal to 0. Assumption: If DFN is a deficit, we assume that the deficit amount is raised by issuing new common shares. If DFN is a surplus, we assume that the surplus is used to repurchase stocks. You should set a dummy variable (0, 1) in Excel to control (disable/enable) the iterative calculations.
Perform financial analysis for Cisco Systems, Inc. including historical data, linear trend extrapolation, regression analysis, forecasting, and iteration calculations in Excel.
Step 1: Gather historical financial statements: Obtain the historical financial statements of Cisco Systems, Inc. for the past five years (2017 to 2021 or 2018 to 2022). These statements include the Income Statement, Balance Sheet, and Cash Flow Statement.
Step 2: Perform linear trend extrapolation: Use the TREND function in Excel to forecast the sales of Cisco Systems, Inc. for the years 2022 to 2026 (or 2023 to 2027). This function uses the historical sales data to establish a linear trend and extrapolate it into the future years.
Step 3: Conduct regression analysis: Perform a regression analysis to examine the relationship between sales and inventory of the company. Calculate the coefficient, t-statistic for the coefficient, R-squared, R-squared adjusted, and F-statistic. Interpret these results to understand the strength and significance of the relationship between sales and inventory.
Step 4: Forecast financial statements: Utilize the percent of sales method to forecast the financial statements (Income Statement and Balance Sheet) for the next year, 2022 (or 2023), for Cisco Systems, Inc. This method estimates the various financial statement items based on the projected sales figure.
Step 5: Iteration calculations: Use iteration calculations in Excel to adjust the pro forma balance sheet if the DFN (Debt Financing Need) is not equal to zero. If DFN is negative (deficit), assume it is covered by issuing new common shares. If DFN is positive (surplus), assume it is used to repurchase stocks. Set a dummy variable in Excel to control the iterative calculations.

What is the value at the front (or top) of the c++ queue o, after these operations? queue int> Q; Q.push(5); Q.push(4): Q.push (6); Q.pop() Q.push (7): Q.pop(); A. 7 B. 5 C. 6 D. 4
After the given operations of push and pop on the C++ queue, the value at the front is determined to be 6. So, the answer is C. 6.
After the given operations, the value at the front (or top) of the C++ queue `Q` can be determined. Let's go through the operations step by step:
1. `Q.push(5);` - This inserts the value 5 into the queue. The queue now contains [5].
2. `Q.push(4);` - This inserts the value 4 into the queue. The queue now contains [5, 4].
3. `Q.push(6);` - This inserts the value 6 into the queue. The queue now contains [5, 4, 6].
4. `Q.pop();` - This removes the front element of the queue, which is 5. The queue now contains [4, 6].
5. `Q.push(7);` - This inserts the value 7 into the queue. The queue now contains [4, 6, 7].
6. `Q.pop();` - This removes the front element of the queue, which is 4. The queue now contains [6, 7].
Therefore, after these operations, the value at the front of the queue `Q` is 6.

#run the code below to create confusion matrix for Q8 and 29 rule <- 1/5 yhat <-as.numeric (fit$fitted>rule) (t<-table (yhat, actual Subscription Status-tlmrk$subscribe)) actualSubscriptionStatus yhat 0 1 0 3608 179 1 392 342 D Question 81 For a classification rule of 1/5, find the sensitivity (recall). Report your answer as a probability (do not transform into a percent). Question 9 For a classification rule of 1/5, find the PPV (precision). Report your answer as a probability (do not transform into a percent). Question 10 10 pts 10 pts
You can calculate sensitivity (recall) and PPV (precision) using the confusion matrix you provided. Sensitivity (recall) measures the proportion of actual positives that are correctly identified, while PPV (precision) measures the proportion of predicted positives that are correct.
To calculate sensitivity (recall), you need to divide the true positive (TP) by the sum of true positives (TP) and false negatives (FN):
Sensitivity = TP / (TP + FN)
To calculate PPV (precision), you need to divide the true positive (TP) by the sum of true positives (TP) and false positives (FP):
PPV = TP / (TP + FP)
Based on the confusion matrix you provided:
actualSubscriptionStatus
yhat 0 1
0 3608 179
1 392 342
We can see that TP = 342, FP = 392, and FN = 179.
Calculating sensitivity (recall):
Sensitivity = 342 / (342 + 179)
Calculating PPV (precision):
PPV = 342 / (342 + 392)
Performing the calculations will give you the sensitivity and PPV values. Remember to report them as probabilities, without transforming into percentages.

1 Discussion: Technology in the Media
Create one initial post and follow up with at least two response posts.
For your initial post, address the following:
Briefly describe the popular culture example (a specific television show episode, commercial, game, movie, etc.) you selected.
How does your example portray or reflect technology? Refer to specific elements of your chosen media example to illustrate this.
The television show episode that I have selected to illustrate the relationship between technology and the media is Black Mirror.
Black Mirror:
In the series, we see a plethora of devices, software, and hardware that are used to communicate, entertain, and control the environment. In particular, the episode "Nosedive" showcases the negative aspects of technology and social media in particular. The story follows a young woman named Lacie who lives in a society where social media ratings determine one's social standing. People who have high ratings enjoy numerous privileges, such as better jobs, housing, and access to exclusive events. However, those with low scores are ostracized and subjected to discrimination, similar to the caste system prevalent in India. Lacie, who has a low score, decides to make a bold move and attend the wedding reception of her former friend Naomi. She hopes to raise her score by mingling with the bride who has a high score. However, her plan backfires when she experiences a series of unfortunate events that cause her score to plummet. She ends up getting arrested and losing her freedom. However, the most significant takeaway from the episode is the use of technology in controlling the masses. People in this society are heavily reliant on their smartphones, and they use them to rate each other's social status. The ratings are then used to control their behavior, such as their purchasing habits, job opportunities, and access to facilities. The episode illustrates how technology can be used to manipulate people and create a dystopian society where the majority of the population is under control. Overall, the episode serves as a cautionary tale about the power of technology and how it can impact our lives negatively.
