Write the command and explain about each formula in MS Excel
1. SUM
2. AVERAGE
3. MAx
4. MIN
5. COUNT
Answer:
1. SUM --- The SUM function is used to sum all the values that are in a given range. Thus, for example, if you want to add the values between cells A1 and A3, you must write the following command: =SUM(A1:A10)
2. AVERAGE --- The AVERAGE function allows you to average a range of values, throwing the average of these values in the cell where the function is typed. For example, if you want to average the values included between B1 and B3, you should write the following function: =AVERAGE (B1: B3).
3. MAX --- The MAX function, for its part, returns the maximum value of the values included in the function. For example, if the maximum value included between the values C1 and C3 is known, the following function must be written: =MAX (C1: C3).
4. MIN --- The MIN function, in turn, allows to identify the minimum value of the range of values included in the function. For example, if the minimum value included between the values D1 and D3 is known, the following function must be written: =MIN (D1: D3).
5. COUNT --- The COUNT function, finally, is used to count all the cells that have numbers, which have been included in the range of the function. For example, if you want to count all cells that contain numbers between the values E1 and E3, you must write the following function: =COUNT (E1: E3).

Organizations can use dictionaries to disallow passwords during the reset process and thus guard against easy-to-guess passwords.
a) true
b) false
Answer:
a) true
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
With cybersecurity theory, security standards, frameworks and best practices we can guard against cyber attacks and easy-to-guess passwords.
An example of best practices in cybersecurity is the use of alphanumeric password with certain composition and strength, such as a minimum of eight (8) characters. This would ensure there's a formidable wall to protect data and an unauthorized access or usage of the system network.
A dictionary attack typically involves accessing a list of commonly used passwords by end users rather than a random guess.
Hence, organizations can use dictionaries to disallow passwords during the reset process and thus guard against easy-to-guess passwords.

Explanation:
State what’s printed for each println in the code below:
public static void main(String args[ ])
{
MyClass theObj = new MyClass( );
theObj.gravy = 107.43;
String s = "hello";
int xray[] = {1, 2, 3, 4, 5};
double floozy = 97.4;
myMethod(floozy, theObj, xray, s );
System.out.println(floozy); // Problem 1:
System.out.println(theObj.gravy); //Problem 2:
System.out.println(xray[2]); //Problem 3:
System.out.println(s); //Problem 4:
}
public static void myMethod(double floozy, MyClass anObj, int a[ ], String s)
{
floozy = 13.1;
anObj.gravy = 10.001;
a[2] = 100; s = "good bye";
}
Answer:
Explanation:
Each of the following println statements will print the following values
ystem.out.println(floozy); // Problem 1: 97.4
System.out.println(theObj.gravy); //Problem 2: 107.43
System.out.println(xray[2]); //Problem 3: 100
System.out.println(s); //Problem 4: Hello
This is because out of all of the variables that the myMethod gives a value to, the only variable that is being saved back to the global variable in the main method is a[2]. The other variables are being saved as instance variables and not being returned. Therefore, when the println statements are called they target the local variables in the main method.
What is the recommended solution if a computer performs slowly?
Answer:
Not sure what the class/context is, but here's what I'd do to diagnose a problem like that:
- Check to see what programs have high utilization of system resources in task manager and end them
- Prevent background startup processes from occuring on restart or from running in the background during normal use
- Figure out what hardware component is bottlenecking the system and upgrade it (HDD to SSD would be one example)
- If the issue is malware related, I would "flatten" the PC by wiping the entire system and reinstalling the OS (though some malware can persist even across this)
Source: I've worked as labs support
If a computer is performing slowly, there are several recommended solutions one can try to improve its performance, such as closing unnecessary programs, restarting the computer, etc.
Reviewing the programs that automatically start when the computer boots up and disabling unnecessary startup programs to reduce the time it takes for the computer to start and free up system resources. The specific solution may vary depending on the computer's operating system, hardware, and specific performance issues. It's always a good idea to back up important files before making any changes to your computer's configuration. If the performance issues persist, seeking assistance from a computer technician or IT professional may be necessary.

Use the factorial operation to evaluate 10!.
A) 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
B) 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1
C) 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1
D) 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Answer:
D
Explanation:
The definition of n! is n x (n-1) x (n-2) x ... x 1.
So 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 i.e. D.
Answer:
D) 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Explanation:
The problem here is to use the factorial method to find;
10!
The factorial of any number is given as:
a! = (a - 1) x (a - 2) .........(a - n)
It is the product of any integer from 1 to that number.
So;
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
The solution is therefore 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Write a public static method named insert. The insert method should have the signature insert(String[] words, String newWord, int place), should return a boolean, and should function as described below.
When called, if place does not represent a valid index for words, then the method will return false to indicate the insertion could not be performed and do nothing else. Otherwise the method will insert the String newWord into the array words at the index place, moving each subsequent entry one place further and losing the final String in the array. The method will then return true to indicate the insertion has taken place.
Use the runner class to test this method: do not add a main method to your code in the U6_L4_Activity_One.java file or it will not be scored correctly.
Here is the runner code:
import java.util.Scanner;
public class runner_U6_L4_Activity_One{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Enter array length:");
int len = scan.nextInt();
scan.nextLine();
String[] wordList = new String[len];
System.out.println("Enter values:");
for(int i = 0; i < len; i++){
wordList[i] = scan.nextLine();
}
System.out.println("Enter new String:");
String insWord = scan.nextLine();
System.out.println("Enter place:");
int pos = scan.nextInt();
System.out.println("Method return: " + U6_L4_Activity_One.insert(wordList, insWord, pos));
System.out.print("Array contents: {");
for(int i = 0; i < len-1; i++){
System.out.print(wordList[i] + ", ");
}
System.out.println(wordList[len-1]+"}");
}
}
Answer:
Explanation:
The following code was written in Java and performs the exact requirements listed in the question. It has also been tested by the runner code and works perfectly.
public static boolean insert(String[] words, String newWord, int place) {
if (place > words.length) {
return false;
} else {
for (int x = words.length - 1; x >= 0; x--) {
if (place == x) {
words[x] = newWord;
break;
} else {
words[x] = words[x-1];
}
}
return true;
}
}
Methods are group of code segments that are executed when evoked or called.
The insert public static method in Java, where comments are used to explain each line is as follows:
//This defines the method
public static boolean insert(String[] words, String newWord, int place) {
//This returns false, if the place value is less than the word length
if (place > words.length) {
return false;
}
//If otherwise
else {
//This iterates through the characters of the word, in reverse order
for (int i = words.length - 1; i >= 0; i--) {
//This inserts the new word into the array
if (place == i) {
words[i] = newWord;
break;
} else {
words[i] = words[i-1];
}
}
//This returns true
return true;

1.16 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int currentPrice;
int lastMonthsPrice;
currentPrice = scnr.nextInt();
lastMonthsPrice = scnr.nextInt();
/* Type your code here. */

In this exercise, you will need to create a static method called findString in the MatchingString class that should iterate over String[] arr looking for the exact match of the String that is passed as a parameter.
Return the index of the array where the String is found; if it does not exist in the array, return -1.
For example, if the word “Karel” is passed in, your method would return 1.
Answer:
Explanation:
The following code is written in Java. It is a static method that takes in a String parameter and loops through the String array called arr comparing each element in the array with the word parameter that was passed. If it finds a match the method returns the index of that word, otherwise it will return -1
public static int findString(String word){

Write a program that takes a first name and a major as the input and outputs a message with that name and major as shown below Ex. If the input is Nithya and Art the output is Nithya 18 majoring in Art. Use the names and majors of students in your breakout room to test your code. Note that to separate the name from the major as part of the input, you need to place these inputs on separate lines. For the example above, we would provide the input as follows: Nithya Art Hint If you directly add the names and majors inside the print statement, then the code would not work correctly since it is relying on the contents of the provided variables. You need to use these variables inside your print statement, so that regardless of the provided input, the output will always use those values and be as expected Hint.

A) cout <
B) ofstream
C) dataFile << salary;
D) payroll.dat <
Answer:
dataFile << salary;
Explanation:
To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:
ofstream dataFile;
myfile.open ("payroll.dat");
myfile <<salary;
myfile.close();
This line creates an instance of ofstream
ofstream dataFile;
This line opens the file payroll.dat
myfile.open ("payroll.dat");
This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat
myfile <<salary;
This closes the opened file
myfile.close();

A user reports slow performance on a computer. A technician checks the computer and finds the RAM utilization Is very high. The technician restarts the computer, and the RAM use is still high. The technician discovers a program running in the background Is using most of the RAM. The user only uses this program once at the end of the year to produce a report. What steps should the technician take to improve the computer's performance?
Answer:
The answer is "disable the program on startup"
Explanation:
The technician simply disables the program on the startup, at this the utilization of the RAM is low. The startup tab is also known as an alternative in the initialization process of the system software, which is automatically started whenever the device boots. There has been an error. If you boot, the more applications you want to load the longer it will take to operate the computer.
