Explanation:
Start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours, we would have 2000 organisms.
Write a program that takes these inputs and displays a prediction of the total population.
MY PROGRAM:
organisms=int(input("Enter the initial number of organisms:"))
growth=float(input("Enter the rate of growth [a real number > 1]:"))
numHours=int(input("Enter the number of hours to achieve the rate of growth:"))
totalHours=int(input("Enter the total hours of growth:"))
population = organisms
hours=1
while numHours < totalHours:
population *= growth
hours += numHours
if hours >= totalHours:
break
print(" The total population is ", population)
My program gives the correct answer for the original problems numbers, but when I run it through our test case checker it comes back as 3/4 correct.. the problem test case being [organisms 7, growth rate 7, growth period 7, total hours 7]... can't see where I'm going wrong...
Answer:
It looks like there are a few issues with your program.
First, the line hours += numHours should be hours += 1. This is because you want to increment the hours variable by 1 each time through the loop, not by the number of hours required to achieve the growth rate.
Second, you are only multiplying the population by the growth rate once per iteration of the loop, but you should be doing it every time hours is less than or equal to totalHours. You can fix this by moving the population *= growth line inside the loop's if statement, like this:
while numHours < totalHours:
if hours <= totalHours:
population *= growth
hours += 1
if hours >= totalHours:
break
Finally, you are using the variable numHours in your while loop condition, but it should be hours. You should change while numHours < totalHours: to while hours < totalHours:.
With these changes, your program should work correctly for the test case you provided. Here is the modified version of your program:
organisms=int(input("Enter the initial number of organisms:"))
growth=float(input("Enter the rate of growth [a real number > 1]:"))
numHours=int(input("Enter the number of hours to achieve the rate of growth:"))
totalHours=int(input("Enter the total hours of growth:"))
population = organisms

Which of the following devices can store large amounts of electricity, even when unplugged?
LCD monitor
DVD optical drive
CRT monitor
Hard disk drive
Even when unplugged, a CRT (Cathode Ray Tube) monitor can store a lot of electricity. The capacitors within CRT monitors can store enough power to be fatal, thus you should never open one.
What does CRT stand for?An electron beam striking a phosphorescent surface creates images in a cathode-ray tube (CRT), a specialized vacuum tube. CRTs are typically used for desktop computer displays. The "picture tube" in a television receiver is comparable to the CRT in a computer display.
What characteristics does CRT have?Flat screen, touch screen, anti-reflective coating, non-interlaced, industrial metal cabinet, and digital video input signal are typical features of CRT monitors. As opposed to the typically curved screen found in most CRT displays, the monitor's screen can be (almost) flat.

Answer:
CRT monitor
Explanation:
A cathode ray tube (CRT) monitor can store large amounts of electricity, even when unplugged. You should never open a CRT monitor, as the capacitors within the CRT can store enough electricity to be lethal.
LCD monitors do not use large capacitors and are much safer to work on than CRT monitors (although the CCFL backlight has mercury vapor in it, which could be harmful if the tube is broken).
DVD optical drives and hard disk drives do not store electricity in sufficient quantity to be harmful.

- int* ShiftByOne(int[], int);
This function accepts an int array and the array’s size as arguments. The
function should shift all values by 1. So, the 1st element of the array should
be moved to the 2nd position, 2nd element to the 3rd position, and so on so
forth. Last item should be moved to the 1st position. The function should
modify the input array in place and return a pointer to the input array.
- Int* GetMax(int[], int);
This function accepts an int array and the array’s size as arguments. The
function should return the memory address of the maximum value found in
the array.

This function accepts a character array (C-String) and should return the size
of the array.
The program that has the following functions is given below:
The Program#include <algorithm>
int* ShiftByOne(int array[], int size) {
int temp = array[size - 1];
for (int i = size - 1; i > 0; i--) {
array[i] = array[i - 1];
}
array[0] = temp;
return array;
}
int* GetMax(int array[], int size) {
int max_val = *std::max_element(array, array + size);

A deferred annuity is an annuity which delays its payouts. This means that the payouts do not start until after a certain duration. Notice that a deferred annuity is just a deposit at the start, followed by an annuity. Your task is to define a Higher-order Function that returns a function that takes in a given interest rate and outputs the amount of money that is left in a deferred annuity.
Define a function new_balance(principal, gap, payout, duration) that returns a single-parameter function which takes in a monthly interest rate and outputs the balance in a deferred annuity. gap is the duration in months before the first payment, payout is monthly and duration is just the total number of payouts.
Hint: Note that duration specifies the number of payouts after the deferment, and not the total duration of the deferred annuity.
def new_balance(principal, gap, payout, duration):
# Complete the function
return
# e.g.
# test_balance = new_balance(1000, 2, 100, 2)
# result = test_balance(0.1)
Test Case:
new_balance(1000, 2, 100, 2)(0.1) 1121.0
Answer:
def new_balance(principal, gap, payout, duration):
def calculate_balance(interest_rate):
balance = principal
for i in range(gap):
balance *= (1 + interest_rate/12)
for i in range(duration):
balance *= (1 + interest_rate/12)
balance -= payout
return balance
return calculate_balance
Explanation:
Answer:
def new_balance(principal, gap, payout, duration):
# convert monetary amounts to cents
principal_cents = principal * 100
payout_cents = payout * 100
def balance(rate):
# calculate the interest earned during the deferment period in cents
interest_cents = principal_cents * (1 + rate) ** gap - principal_cents
# calculate the balance after the first payout in cents
balance_cents = interest_cents + principal_cents - payout_cents
# loop through the remaining payouts, calculating the balance after each one in cents
for i in range(duration - 1):
balance_cents = balance_cents * (1 + rate) - payout_cents
# convert the balance back to dollars and round it to the nearest cent
balance_dollars = round(balance_cents / 100)
return balance_dollars
return balance
test_balance = new_balance(1000, 2, 100, 2)
result = test_balance(0.1)

A sequential circuit has one flip-flop Q, two inputs X and Y, and one output S. The circuit consists of a D flip-flop with S as its output and logic implementing the function D = X ⊕ Y ⊕ S with D as the input to the D flip-flop. Derive the state table and state dia- gram of the sequential circuit.
To derive the state table and state diagram of the sequential circuit, we first need to determine the possible states of the flip-flop Q, and the next states based on the input values X and Y and the current state of Q.
The state table for the sequential circuit would look like this:
Q(t) X Y Q(t+1) S
0 0 0 0 0
0 0 1 1 1
0 1 0 1 1
0 1 1 0 0
1 0 0 1 1
1 0 1 0 0
1 1 0 0 0
1 1 1 1 1
The state diagram for the sequential circuit would look like this:
S=0 S=1
------------ ------------
| 0 | | 1 | | 1 | | 0 |

What is flip-flop Q?
A flip-flop is a circuit that is used to store binary data in digital electronic systems. It is a type of latch circuit that is used as a memory element in digital logic circuits. Flip-flops can be either positive edge-triggered or negative edge-triggered, and can be either level-sensitive or edge-sensitive. The most common types of flip-flops are SR flip-flops, JK flip-flops and D flip-flops.
In this case, Q is a flip-flop that is used as a memory element in the sequential circuit. It stores the current state of the circuit and is used in the logic implementation of the circuit's function. The output of this flip-flop is used as an input to the next state of the circuit, and it's also the output of the circuit.

One constructor must be a default.
One constructor must be an x and y only constructor.
One constructor must be an x, y, and speed constructor.
Provide all accessor and mutator methods needed to complete the class.
Add a increaseSpeed method to make the Ship speed up according to a parameter passed in.
Provide an equals method to determine if 2 Ships are the same(i.e. in the same location).
You also must provide a toString() method.
The toString() should return the x, y, and speed of the Ship.
In order to test your newly created class, you must create another class called ShipRunner. There you will code in the main method and create at least 2 Ship objects (although you can create more if you like), using the constructors you created in the Ship class. Then you will print them out using the toString method and compare them with the equals method.

Suppose that you have a list of numbers, and you need to normalize the list, i.e., the sum of all numbers in the list is equal to 1.
Tam came out with an implementation:
def normalize(lst):
s = sum(lst)
return list(map(lambda v: v / s, lst))
This code works correctly for normalize([1, 2, 5, 4]) but fails for normalize([1, 2, -7, 4]). What causes the second test case to fail?
Find out the error message and keep the list as it is when the error occurs by simply return the list. So without modifying the normalize function, implement this strategy in the safe_normalize function. Complete safe_normalize. You may assume that the normalize function has already been defined for you.
def safe_normalize(lst):
# handle the error
return normalize(lst)
Test Cases:
safe_normalize([1, 2, 2, 3]) [0.125, 0.25, 0.25, 0.375]
safe_normalize([1, 2, -5, 2]) [1, 2, -5, 2]
Here is an implementation of the safe_normalize function that catches the error and returns the original list if an error occurs:
def safe_normalize(lst):
try:
return normalize(lst)
except ZeroDivisionError:
return lst
This function calls the normalize function, which takes a list as input and returns a normalized list. However, if an error occurs (in this case, a ZeroDivisionError), the function will catch the error and return the original list instead.
To test the safe_normalize function, you can use the following test cases:
print(safe_normalize([1, 2, 2, 3])) # Expected output: [0.125, 0.25, 0.25, 0.375]
print(safe_normalize([1, 2, -5, 2])) # Expected output: [1, 2, -5, 2]
The first test case should return the normalized list, while the second test case should return the original list, since the normalize function would fail with a ZeroDivisionError if passed a list with a negative sum.

answer
The MRS y,x = 12 means that the ratio of marginal utilities between two goods (y and x) is 12. This means that for every 12 units of good y the consumer will give up 1 unit of good x. This holds true if the consumer has constant marginal utility.
