Explanation:
You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input
5
40.0
12.0
20.0
5. 33.
0
Output
- 18.0
10.0
2.0
17.0
-11.0
Answer:
The program in C++ is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int cars;
cin>>cars;
double weights[cars];
double total = 0;
for(int i = 0; i<cars;i++){
cin>>weights[i];
total+=weights[i]; }
double avg = total/cars;
for(int i = 0; i<cars;i++){
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
return 0;
}
Explanation:
This declares the number of cars as integers
int cars;
This gets input for the number of cars
cin>>cars;
This declares the weight of the cars as an array of double datatype
double weights[cars];
This initializes the total weights to 0
double total = 0;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This gets input for each weight
cin>>weights[i];
This adds up the total weight
total+=weights[i]; }
This calculates the average weights
double avg = total/cars;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This prints how much weight to be added or subtracted
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }

The divBySum method is intended to return the sum ofall the elements in the int arrayparameter arr that are divisible by the intparameter num. Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized. The method must use anenhanced for loop to earn full credit./** Returns the sum of all integers inarr that are divisible by num* Precondition: num > 0*/public static int divBySum(int[] arr, int num)

Answer:
c is the answer hope you get it right
The effect when one part of a system changes C. The open-loop system becomes a closed-loop system.
Systemic change is generally understood to require adjustments or transformations in the policies, practices, power dynamics, social norms or mindsets that underlie the societal issue at stake. It often involves the collaboration of a diverse set of players and can take place on a local, national or global level.
How does a systemic change happen?All systems organize individual pieces into some sort of interrelated whole. Put simply, systemic change occurs when change reaches all or most parts of a system, thus affecting the general behavior of the entire system.
Why is systems change important?A systems-change approach is more appropriate for problems that are complex, unpredictable, and context-dependent. For example, the challenge of inadequate access to educational opportunities for children from low-income neighborhoods cannot be addressed with a straightforward, logistical fix.

The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.
1 - def countdown_trigger (begin):
2 i = begin
3 while i < 0:
4 print(i)
5 i -= 1 Restore original file
Answer:
Follows are code to the given question:
def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter
i = begin#defining variable that holds parameter value
while i >= 0:#defining while loop that check i value greater than equal to0
print(i)#print i value
i -= 2 # decreasing i value by 2
print(countdown_trigger(2))#calling method
Output:
2
0
None
Explanation:
In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.
By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.

The program then prints the sum, average (arithmetic mean), maximum, and minimum of the values entered. Algorithm: Get all positive numbers from the user Terminate the list of numbers when user enters a negative
Answer:
The program in Python is as follows:
nums = []
isum = 0
num = int(input("Num: "))
while num >= 0:
isum+=num
nums.append(num)
num = int(input("Num: "))
print("Sum: ",isum)
print("Average: ",isum/len(nums))
print("Minimum: ",min(nums))
print("Maximum: ",max(nums))
Explanation:
My solution uses list to answer the question
This initializes an empty list, num
nums = []
This initializes the sum of the input to 0
isum = 0
This prompts the user for input
num = int(input("Num: "))
The loop is repeated until the user enters a negative number
while num >= 0:
This calculates the sum of the list
isum+=num
This appends the input to the list
nums.append(num)
This prompts the user for another input
num = int(input("Num: "))
This prints the sum of the list
print("Sum: ",isum)
This prints the average of the list
print("Average: ",isum/len(nums))
This prints the minimum of the list
print("Minimum: ",min(nums))
This prints the maximum of the list
print("Maximum: ",max(nums))
If a system contains 1,000 disk drives, each of which has a 750,000- hour MTBF, which of the following best describes how often a drive failure will occur in that disk farm:
a. once per thousand years
b. once per century, once per decade
c. once per year, once per month
d. once per week
e. once per day
f. once per hour
g. once per minute
h. once per second
Answer:
once per month
Explanation:
The correct answer is - once per month
Reason -
Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs
So,
750/24 = 31.25 days
⇒ approximately one in a month.
Create a script that will determine how many of each currency type are needed to make change for a given amount of dollar and cents. Input Asks the user for a dollar and cents amount as a single decimal number. Output The program should indicate how many of each of these are needed for the given amount: $20 bills $10 bills $5 bills $1 bills Quarters ($0.25 coin) Dimes ($0.10 coin) Nickels ($0.05 coin) Pennies ($0.01 coin) If a dollar or coin is not needed (its quantity required is 0), do not print it.
Answer:
The program in Python is as follows:
dollar = float(input("Dollars: "))
t20bill = int(dollar//20)
dollar -= t20bill * 20
t10bill = int(dollar//10)
dollar -= t10bill * 10
t5bill = int(dollar//5)
dollar -= t5bill * 5
t1bill = int(dollar//1)
dollar-= t1bill * 1
qtr = int(dollar//0.25)
dollar -= qtr * 0.25
dime = int(dollar//0.10)
dollar -= dime * 0.10
nkl = int(dollar//0.05)
dollar -= nkl * 0.05
pny = round(dollar/0.01)
if t20bill != 0: print(t20bill,"$20 bills")
if t10bill != 0: print(t10bill,"$10 bills")
if t5bill != 0: print(t5bill,"$5 bills")
if t1bill != 0: print(t1bill,"$1 bills")
if qtr != 0: print(qtr,"quarters")
if dime != 0: print(dime,"dimes")
if nkl != 0: print(nkl,"nickels")
if pny != 0: print(pny,"pennies")
Explanation:
This gets input for dollars
dollar = float(input("Dollars: "))
Calculate the number of $20 bills
t20bill = int(dollar//20)
Calculate the remaining dollars
dollar -= t20bill * 20
Calculate the number of $10 bills
t10bill = int(dollar//10)
Calculate the remaining dollars
dollar -= t10bill * 10
Calculate the number of $5 bills
t5bill = int(dollar//5)
Calculate the remaining dollars
dollar -= t5bill * 5
Calculate the number of $1 bills
t1bill = int(dollar//1)
Calculate the remaining dollars
dollar-= t1bill * 1
Calculate the number of quarter coins
qtr = int(dollar//0.25)
Calculate the remaining dollars
dollar -= qtr * 0.25
Calculate the number of dime coins
dime = int(dollar//0.10)
Calculate the remaining dollars
dollar -= dime * 0.10
Calculate the number of nickel coins
nkl = int(dollar//0.05)
Calculate the remaining dollars
dollar -= nkl * 0.05
Calculate the number of penny coins
pny = round(dollar/0.01)
The following print the number of bills or coins. The if statement is used to prevent printing of 0
if t20bill != 0: print(t20bill,"$20 bills")
if t10bill != 0: print(t10bill,"$10 bills")
if t5bill != 0: print(t5bill,"$5 bills")
if t1bill != 0: print(t1bill,"$1 bills")
if qtr != 0: print(qtr,"quarters")
if dime != 0: print(dime,"dimes")
if nkl != 0: print(nkl,"nickels")
if pny != 0: print(pny,"pennies")

Course Project Part 4: Conducting the Experiment and Recording Data
After much preparation, you are finally ready to begin conducting your experiment. Due to all the hard work you put into your literature review and planning your procedures, the steps that you need to take to conduct your experiment successfully have already been set. While you conduct your experiment, you will need to keep a daily journal where you record the activities you undertake that are relevant to the experiment and also where you record any data that you collect. This is your experiment log and serves as a record of your work while also allowing you to make a record of any changes or modifications you may need to make during the experiment.
Conducting the Experiment and Keeping an Experiment Journal
Following the procedure that you established in the previous part of this project, set up your experiment and begin running it. Every day while your experiment is running you will make an entry in your journal. Record what activities you completed (refer to your outlined procedure to make sure you are following the procedure that you established), any modifications that had to be made to your set up or procedure, and any observations or data you collect. Even on days when you do not collect data (depending on your experiment, there may not be data collection every day), make an entry in your journal. Each journal entry should be clearly labeled with the date on which it was entered. You do not need to type up all your entries, but make sure that your journal entries are neatly written, as they will be evaluated by your instructor.
Depending on the topic and design of your experiment, the period of time during which you conduct and record your experiment may range from one to several weeks. In consultation with your instructor, you will establish a timeline for the evaluation of your journal. If you are running a shorter experiment, your journal may be evaluated several times over the course of one or two weeks. If your experiment takes longer to complete, you may have a weekly review over the course of a month. Follow the guidelines provided by your instructor.
Collecting Data
All experiments generate data. This data allows the scientist to evaluate the success of the experiment and make interpretations about the results generated by the investigation. When you record your data, you must collect it as consistently as possible. Returning to the plant experiment, it would be best to measure the plants on a set schedule. For example, you might choose to measure the plants every Thursday at 3 pm. It is important to measure the plants at the same time each week so that the difference in growth you might observe is a reflection of the experimental condition, not simply longer growing time. Additionally, it is important to use the same instruments to collect data. The plants should be measured with the same ruler or measuring tape each time. This helps reduce any error or bias that might be introduced by using different instruments to make measurements. Whatever measurements or data you collect, do so in a consistent manner. Use the same instruments, the same scales, and record the data in a standardized manner. It is also a good idea to record your experiment using photographs. This will help you later during analysis and provides information for others who might be interested in recreating your experiment. Record your data in your experiment journal, where it will be reviewed by your teacher on an on-going basis. Submit your journal to your instructor according to the schedule you have established together.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.
Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.
Answer:
In Python:
prices = []
pounds = []
print("Enter 0 to stop input")
for i in range(10):
pr = float(input("P rice: "+str(i+1)+": "))
pd = float(input("Pound: "+str(i+1)+": "))
if pr != 0 and pd != 0:
prices.append(pr)
pounds.append(pd)
else:
break
amount = 0
for i in range(len(pounds)):
amount+= (pounds[i]*prices[i])
print("Amount: $",amount)
Explanation:
These initialize the prices and pounds lists
prices = []
pounds = []
This prompts the user to enter up to 10 items of press 0 to quit
print("Enter 0 to stop input")
This iterates through all inputs
for i in range(10):
This gets the price of each item
pr = float(input("P rice: "+str(i+1)+": "))
This gets the pound of each item
pd = float(input("Pound: "+str(i+1)+": "))
If price and pound are not 0
if pr != 0 and pd != 0:
The inputs are appended to their respective lists
prices.append(pr)
pounds.append(pd)
If otherwise, the loop is exited
else:
break
This initializes total to 0
amount = 0
This iterates through all inputs
for i in range(len(pounds)):
This multiplies each pound and each price and sum them up
amount+= (pounds[i]*prices[i])
The total is then printed
print("Amount: $",amount)
