Repeat
- a. Sedentary
- b. Somewhat active (exercise occasionally)
- c. Active (exercise 3-4 days per week)
- d. Highly active (exercise every day)
If the user answers “Sedentary.” then increase the calculated BMR by 20 percent. If the user answers “Somewhat active.” thon increase the calculated BMR by 30 percent. If the user answers “Active.” then increase the calculated BMR by 40 percent. Finally, if the user answers “Highly active,” then increase the calculated BMR by 50 percent. Output the number of chocolate bars based on the new BMR value.

TASK
" Write a program that grades students' exam. The exam
has 20 multiple choice questions. Here are the correct
answers:
1- A 6- B 11-C 16- D
2- A 7- B 12- C 17- D
3- А 8- В 13-С 18- D

"A student must correctly answer 15 of the 20 questions to
pass the exam.
" Write a class named StudentExam that holds the correct
answers to the exam in an array.
TASK (CONT.)
" The class should also have an array that holds the student's
answers. The class also should have the following methods:
I passed. Returns true if the student passed the exam, or false if the
student failed
" totalCorrect. Returns the total number of correctly answered
questions
I totallncorrect. Returns the total number of incorrectly answered
questions
" questionsMissed. An int array containing the question numbers of the
questions that the student missed.

his answers and display the results returned from the
StudentExam…
A student took four quizzes in a term and would like to compute their average. He also would like to know what will be the remarks. Follow the range of grades and its equivalent remarks, and then fill-up the table below:100-95 - Excellent94-90 – Very Satisfactory89-85 - Satisfactory84-80 - Fine79-75 - Fair74 and below – Poor
. What statement in the program that determines that the average is passing? 2. What was the condition applied to satisfy the requirement?3. What have you observed in using if-else statement in this program?4. What have you observed in using nested if statement in this program?
The objective of this program is to demonstrate your proficiency with the if-elif-else construct.
Your program will consist of a simple guessing game. Using the random module, generate an integer
between 1 and 10. This will be the secret.
You will then ask the user for a guess between 1 and 10.
. If the guess is greater than the secret respond, "Too high".
• If the guess is less than the secret respond, "Too low".
. If both numbers are equal respond, "Success!".
Remember to test your program to ensure that all of the comparisons work.
Please note that a loop is not required. The images below shows the program being run multiple
times to display the three different possible output messages.
Your display should look like this. User input is highlighted in green.
Please enter your guess: 10
Too high!
Please enter your guess: 5
Too low!
Please enter your guess: 1
Success!

- MATLAB The Mach number is a critical quantity in aerodynamics. It is the ratio of the speed of an object (e.g., an aircraft) to the speed of sound. If the Mach number is less than 1, the flow is subsonic; if the Mach number is between (0.8-1.2), the flow is transonic; if the Mach number is equal to 1, the flow is sonic; if the Mach number is between (1.2 and 5), the flow is supersonic; if the Mach number is greater than 5, the flow is hypersonic. Write a script that will prompt the user for the speed of an aircraft and the speed of sound at the aircraft's current altitude and will print whether the condition is subsonic, transonic, sonic, supersonic or hypersonic.arrow_forwardPlease answer in matlab code.arrow_forwardpython solution please Task 1Description let's consider a case when you need a lot of coffee. Maybe you're hosting a party with a lot of guests! In these circumstances, it's better to make preparations in advance.So, we will ask a user to enter the desired amount of coffee, in cups. Given this, you can adjust the program by calculating how much water, coffee, and milk are necessary to make the specified amount of coffee.Of course, all this coffee is not needed right now, so at this stage, the coffee machine doesn't actually make any coffee yet. ObjectivesLet's break the task into several steps:First, read the numbers of coffee drinks from the input.Figure out how much of each ingredient the machine will need. Note that one cup of coffee made on this coffee machine contains 200 ml of water, 50 ml of milk, and 15 g of coffee beans.Output the required ingredient amounts back to the user.

- 1. Write a program that converts miles to feet. If the distance is more than 15,000 feet, tell the user it might be beneficial to drive the distance. Print the distance in both regular and scientific notation (Note: 1 mile = 5280 feet).arrow_forwardWhen you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forward60.
