When Jacob Steinberg began his trip from California to Vermont, he filled his car’s tank with gas and reset its trip meter to 0. After traveling 324 miles, Jacob stopped at a gas station to refuel; the gas tank required 17 gallons. Jacob wants a program that calculates and displays his car’s gas mileage at any time during the trip. The gas mileage is the number of miles his car can be driven per gallon of gas. Desk-check your solution’s algorithm using 324 as the number of miles driven and 17 as the number of gallons used; then desk-check it using 280 and 15.

(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
When 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.)
Airline 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. Geri bildirim gönder
Instructions A local biologist needs a program to predict population growth. The inputs would be: 1. The initial number of organisms, as an int 2. The rate of growth (a real number greater than 1), as a float 3. The number of hours it takes to achieve this rate, as an int 4. A number of hours during which the population grows, as an int For example, one might 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. An example of the program input and output is shown below: Enter the initial number of organisms: 10 Enter the rate of growth (a real number › 1]: 2 Enter the number of hours to achieve the…
A movie in a local theater is in great demand. To help a local charity, the theater owner has decided to donate a portion of the gross amount generated from the movie to the charity. This example designs and implements a program that prompts the user to input the movie name, adult ticket price, child ticket price, number of adult tickets sold, number of child tickets sold, and percentage of the gross amount to be donated to the charity. The output of the program is as follows: ** The input to the program consists of the movie name, adult ticket price, child ticket price, number of adult tickets sold, number of child tickets sold and percentage of the gross amount to be donated to the charity.

Phyton The program that you create for this exercise will begin by reading the cost of a meal ordered at a restaurant from the user. Then your program will compute the tax and tip for the meal. Use your local tax rate when computing the amount of tax owing. Compute the tip as 18 percent of the meal amount (without the tax). The output from your program should include the tax amount, the tip amount, and the grand total for the meal including both the tax and the tip. Format the output so that all of the values are displayed using two decimal places.
Exercise 2: Because of the high price of petrol, you are concerned with the fuel consumption of your car. As a result, you have a record of the kilometers driven and liters used for each tank of petrol you purchase. Write a program that will display the kilometers driven, liters used, and consumption (in liters/100km) for each tankful. After processing all the input information, the program should calculate the overall average consumption: Enter the liters used (-1 to end): 57.6 Enter the kilometers driven: 459 The liters/100km for this tank was 12.5 Enter the liters used (-1 to end): 45.3 Enter the kilometers driven: 320 The liters/100km for this tank was 14.2 Enter the liters used (-1 to end): -1 The overall average consumption was: 13.4 Code: Output:
