- (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.arrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forwardThe text output of a program should be well-formatted for readability as well as displaying numbers with the proper notation and precision levels. The default output formatting in C++ is often not desirable, so one can add explicit instructions to the cout stream. These manipulators and functions are defined in the library. O setw (n): set the width (number of characters) of the next item to be at least n. • If the next item width is less than n, then pad the item with extra spaces. • If the next item width is greater than n, then the entire next item is output. • left and right: when used in conjunction with setw (), justify the item to one side forcing the padding to the other side. Note that these manipulators are persistent, i.e. remains effective until the next change occurs. • fixed: use the fixed-point notation (the decimal point notation that we are familiar with) when displaying a numerical item. Note that fixed defaults to 6 decimal points if the data type is float or…arrow_forward

The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…arrow_forwardExercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solutionarrow_forward
- Periodic compounding The total accumulated value, including the principal sum P, is given by the formula: where: nt A = P(1 + 1) "² n A is the final amount Accumulated Value P is the original principal sum r is the nominal annual interest rate n is the compounding frequency t is the overall length of time the interest is applied (expressed using the same time units as r, usually years). Using the above formula write a program that will display the following table. Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value 1000 6.00% 10 3.20% 15 2000 3000 9.25% 10 2 ** 3 8 | You must use exponent operator to compute P Exponent Operator in Python is ** Examples m=3 n=2 p= m **n (https://en.wikipedia.org/wiki/Compound_interest) 1 2 4 base = 2 exp = 4 a = base ** exp print(a) 16 print("Solving the exponent, we get Solving the exponent, we get 9 ,p ) 1790.85 3219.89 7486.33arrow_forwardneed help!arrow_forwardLIFE INSURANCE PREMIUM CALCULATOR Write a C program that calculates monthly, quarterly, half-yearly and yearly life insurance premium based on given sum assured.

- 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 gönderarrow_forwardA company of 20 employees wants to find the employee who made the highest commission so he/she can be paid a 10% bonus of the commission he/she earned for that month. The commission an employee makes is calculated by multiplying the sales amount by the commission rate. The commission rates are shown below: Sales Amount Commission Less Than 40000 No commission 40000 to 80000 inclusive 5% Greater than 80000 10% Write a program to: Prompt the user for each employee’s id (an integer value) and the sales amount For each employee, display the commission earned Display the total commission earned by all the employees Display the average commission earned by an employee Display the employee id, the commission and the bonus paid to the employee with the highest commission Must be written in c++, no arrays to be used, only use iostream libraryarrow_forwardThe monthly payment on a loan may be calculated by the following formula: N Rate * (1 + Rate)* * L/; Payment (1 + Rate)" - 1 Rate is the monthly interest rate, which is the annual interest rate divided by 12. (A 12 percent annual interest would be 1 percent monthly interest.) N is the number of payments and L is the amount of the loan. Write a program that asks for these values and displays a report similar to the following: $ 10000.00 Loan Amount: Monthly Interest Rate: Number of Payments: Monthly Payment: Amount Paid Back: 18 36 $ $ 11957.15 $ 1957.15 332.14 Interest Paid:arrow_forward
