- (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_forwardAssignment 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.

- 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.

Their "magnificence" is quantified by the rather simple process of counting the exact number of tail feathers and multiplying this by the difference in the length of the minimum and maximum lengths of tail feather. You are to write a simple program that will allow the user to enter the length of each tail feather individually and keep on entering feathers until a -1 is entered. The program will then return the quantified "magnificence" factor.arrow_forwardHomework write a program that will add the terms of an infinite geometric series.

- MATLAB QUESTION - As of 2018, the population of "A city" is 646 thousand and the population of "B city" is 269 thousand. 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_forward3. 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_forwardWrite a program that can calculate the future and present value of an investment given various parameters. When you calculate the future value of an investment, the more years you hold the investment and the higher the rate of return, the more valuable it is. For example, a $1000 investment at 7% return will give you $1070 (1000+ 0.07-1000) after one year and $1144.90 (1070+0.07-1007) after two years. However, because of inflation, that $1144.90 after two years is not worth the same as $1144.90 now. If the inflation rate is 2%, $1144.90 in two years is the equivalent of $1100.44 now-i.e- 102 More generally, the present value, p, of an investment is 1.02² 1144.90 f p= where is the inflation rate as a percentage. Typically, one would add to the investment with annual contributions. Let's say you start with a $1000 investment and add $100 every year. Therefore, after the first year, you will have $1177 - 7% return on $1100i.e. $1000 initial investment + the $100 year one contribution.…arrow_forward
- Running 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_forwardThe Café Noir Coffee Shop wants some market research on its customers. When a customer places an order, a clerk asks for the customer’s zip code and age. The clerk enters that data as well as the number of items the customer orders. The program operates continuously until the clerk enters a 0 for zip code at the end of the day. When the clerk enters an invalid zip code (more than 5 digits) or an invalid age (defined as less than 10 or more than 110), the program reprompts the clerk continuously. When the clerk enters fewer than 1 or more than 12 items, the program reprompts the clerk two more times. If the clerk enters a high value on the third attempt, the program accepts the high value, but if the clerk enters a negative value onthe third attempt, an error message is displayed and the order is not counted. At the end of the program, display a count of the number of items ordered by customers from the same zip code as the coffee shop (54984), and a count from other zip codes.
