- (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_forwardInterest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.arrow_forward
- The 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_forwardProgram by using C # C sharp My student number :1910206534arrow_forwardTransient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. 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_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.

- solve using paython language and take screenshot contains the codearrow_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_forwardBody Mass Index (BM) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Interpretation Underweight Write a program which prompts the user to enter the weight in kgs (integer value) and height in feet and inches (both integers) and then calculates the BMI of the person. Your program first need to convert inches to meters (L.e. inches 0.0254) and then use the following formula to calculate BM weight kilogram/ (height meter) 2 5 Your program displays the BMI value in two decimal places and the corresponding status as shown in the examples below. Note that one inch is 0.0254 meters and 1 foot is 12 inches. For example: Input Result 62 10 89 6 45 BMI BMI < 18.5 185 BMI <25.0 25.0 < BMI <30.0 30.0 s BMI 5 7 Normal Overweight Obese 82 2 Enter weight (kg): Enter height (feet): Enter height (inches): BMI is 19.61, Normal Enter weight (kg): Enter height (feet): Enter height (inches): BMI is 26.61,…arrow_forward
