The amount of time students spent studying for an test is exponentially distributed with a mean of 25 hours. Write a piece of code to compute the percentage of students who spent between 30 and 40 hours studying for the test? Your code should print out the percentage rounded to 1 decimal place.
An instructor gives a series of exams during the semester in her math class. At the end of
the semester she drops each student's lowest test score before averaging the scores. She has
asked you to design a program that will read a student's test scores as input and calculate
the average with the lowest score dropped. Here is the algorithm that you developed:
Get the student's test scores.
Calculate the total of the scores.
Find the lowest score.
Subtract the lowest score from the total. This gives the adjusted total.
Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average.
Display the average.
The test scores are in a text file named scores.txt and contains the following:
Mickey, 71.0, 42.0, 83.0
Donald, 94.0, 73.0, 72.0, 81.0
Minnie, 95.0, 85.0, 45.0, 55.0, 65.0
A sample run is as follows:
Enter a file containing floating point numbers: scores.txt
Test scores for Mickey: ['71.0', '42.0', '83.0']
Removed the lowest score of 42.0 for Mickey

Amanda and Tyler opened a business that specializes in shipping liquids, such as milk, juice, and water, in cylindrical containers. The shipping charges depend on the amount of the liquid in the container. (For simplicity, you may assume that the container is filled to the top.) They also provide the option to paint the outside of the container for a reasonable amount. Write a program that does the following:
Prompts the user to input the dimensions (in feet) of the container (radius of the base and the height).
Prompts the user to input the shipping cost per liter.
Prompts the user to input the paint cost per square foot. (Assume that the entire container including the top and bottom needs to be painted.)
Separately outputs the shipping cost and the cost of painting. Your program must use the class cylinderType (designed in Programming Exercise 3) to store the radius of the base and the height of the container. (Note that 1 cubic feet = 28.32 liters or 1 liter = 0.353146667 cubic…

- Write a program that asks for the names of three runners and the time it took each of them to finish a race. The program should display who came in first, second, and third place. Think about how many test cases are needed to verify that your problem works correctly. (That is, how many different finish orders are possible?) Input Validation: Only allow the program to accept positive numbers for the times.arrow_forwardYou arrive in front of a bridge that you must cross to reach a village before dark. Crossing the bridge is not free - the bridgekeeper asks you to roll two dice to determine the cost. You decide to write a program to verify that he is charging the right price. Your program should read two integers, between 1 and 6, representing the values of each die. If the sum is greater than or equal to 10, then you must pay a special fee (36 coins). Otherwise, you pay twice the sum of the values of the two dice. Your program must then display the text "Special tax" or "Regular tax" followed by the amount you have to pay on the next line.arrow_forwardWrite a program that reads an integer and checks whether the number is odd or even.You should use the modulus operator (%) to test if the number is odd or even.Example of user dialogue:Enter an integer: 1313 is an odd number.Testing:Try entering different integers, also try with 0 and negative integers.arrow_forward
- Write a program that prompts the user to enter an integer for today’s day of the week (Sunday is 0, Monday is 1, ..., and Saturday is 6). Also prompt the user to enter the number of days after today for a future day and display the future day of the week.arrow_forwardWrite a program that generates a plate number based on the user's answer to the following questions: 1. What is your favorite color of the rainbow (ROYGVIB)? a. Use the first letter of the chosen color as the first character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid color of the rainbow. 2. What is your month of birth? a. Use the last letter of the month as the second character of the plate number. b. Display "Invalid Input" and ask the user to re-enter his/her answer if the answer is not a valid month. 3. What is your first name? a. Use the third letter of the first name as the third character of the plate number. No need to include the second name if you have a second name. Make sure to use "cout" and "cin" to collect the necessary inputs from the user. For the number section: 1.

- f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardAirline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.
