- (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_forwardExercise 6: Write a program that reads from the user three pieces of information: The current population of a country, the annual birth rate of the country, and its annual death rate. The program should then calculate the expected population for the following year and display the results as shown in Figure 6. Please note that population for the following year is calculated as sum of the current population, and the number of births by the end of the year minus the number of deaths by the end of the same year. Name your program Lab3_Id_ex6.py, where Id is your university Id. Include the design of your solution as comments at the beginning of your program. Test your solution with different input data. Please enter the current population of the country: 1800000 Please enter the birth rate: 0.017 Please enter the death rate: 0.005 Current Population Number of Number of Deaths Next Year Births Population 1800000 30600 9000 1821600 Figure 6: Sample Runarrow_forwardPython questionarrow_forward
- Assignment Write a program that tracks how much steps the user walks in total in a day and reports if the daily target is reached or not. The program will keep reading double values, each representing steps walked during an individual activity within a day (stepsWalked) until either the user enters a negative value or the daily target of 5000 steps is met. If the user enters a negative number, the program should print total steps walked as a double. Otherwise, if the target is exactly reached, the program should simply print "Target is reached", finally if the target is surpassed the program should print the text "Target is surpassed by", followed by the excess amount above the target as a double, and finally printing the text "steps". NOTE: YOU MUST use a repetitive statement in this question. NOTE: Each stepsWalked value will be given as a non-negative value. You do NOT need to check this.

The bar chart displays one asterisk for each 10 points scored by a player. For example, if a player has scored 48 points, then display 4 asterisks. An example of the program is shown below: Enter points earned for the season by Art >> 10 by Bob >> 20 by Cal >> 30 by Dan >> 40 by Eli >> 50 Points for Season (each asterisk represents 10 points) Art * Bob ** Cal *** Dan **** Eli ***** import java.util.Scanner; public class BarChart2 { public static void main (String[] args) { Scanner input = new Scanner(System.in); int artPoints; int bobPoints; int calPoints; int danPoints; int eliPoints; final int AMT_EACH_ASTERISK = 10; System.out.println("Enter points earned for the season"); System.out.print(" by Art >> "); artPoints = input.nextInt();…arrow_forward
- Homework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop.

While the population of "A city" decreases by 7.1% every year, the population of "B city" increases by 12.9%. According to this information, write a program that calculates the year in which the population of "B city" passed the population of "A city".arrow_forward
- 3. The formula for determining compound interest is: A represents the amount to earn; P is the principle that is initially invested; r is the interest rate earned; n is the number of times the interest is compounded; and t is the number of time periods for the investment. Write a program that prompts the user to enter P, r, n and t. The program should output the amount earned on the investment. 4. Look up the Pythagorean theorem if you are not already familiar with it. Use the following formula to solve for c in the formula: c = √a2 + b2. Use the proper functions from the cmath header file. Be sure to output the result.larrow_forwardRunning the program Your program should take 5 arguments: start annual years return inflation where start is the initial investment amount annual is the amount that is added to the investment every year years is the number of years that the investment is held return is the annual investment return expressed as a percentage inflation is the annual inflation rate expressed as a percentage So, to calculate the future and present value of $1000 investment after 10 years where you add $100 every year with a 7% return and 2% inflation, you give the following arguments and get this output: $ ./fv 1000 100 10 7 2 Future Value: $3445.51 Present Value: $2826.52 Writing the code Starter code is provided for you below int main(int arge, char **argv ) { int a, n double value, present, I, is value= atof(argv[1]); a = atoi (argv [2]); natoi (argv[3]); r = atof (argv[4])/100; i = atof(argv[5])/100; // TODO write your code here printf("Future Value: $%.2f\n", value) printf("Present Value: $%.2f\n",…arrow_forwardRunning the program Your program should take 5 arguments: start annual years return inflation where start is the initial investment amount annual is the amount that is added to the investment every year years is the number of years that the investment is held return is the annual investment return expressed as a percentage inflation is the annual inflation rate expressed as a percentage So, to calculate the future and present value of $1000 investment after 10 years where you add $100 every year with a 7% return and 2% inflation, you give the following arguments and get this output: $ ./fv 1000 100 10 7 2 Future Value: $3445.51 Present Value: $2826.52 Writing the code Starter code is provided for you below int main(int arge, char **argv ) { int a, n double value, present, I, is value= atof (argv[1]); a = atoi (argv[2]); natoi (argv[3]); r = atof (argv[4])/100; i = atof(argv[5])/100; // TODO write your code here printf ("Future Value: $%.2f\n", value) printf("Present Value: $%.2f\n",…arrow_forward
