2. You are again working for the census bureau and they need some statistics regarding the distribution of ages. Write a program to read in a number of ages. (You do not know upfront how many entries you have, so you need to keep track of it.) Compute the average age and the age that occurs most frequently (some of the ages might be the same). Ages should be read in as integers, the average should be a real number. Calculate the population standard deviation using the formula: Standard deviation = E/n - (ti/n)

f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…
Transient 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…
You are working for a lumber company, and your employer would like a program that calculatesthe cost of lumber for an order. The company sells pine, fir, cedar, maple, and oak lumber.Lumber is priced by board feet. One board foot equals one square foot that is one inch thick. Theprice per board foot is given in the following table: (image 1) The lumber is sold in different dimensions (specified in inches of width and height, and feet oflength) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which whendivided by 12 = 5.333 board feet). An entry from the user will be in the form of a letter and fourinteger numbers. The integers are the number of pieces, width, height, and length. The letter willbe one of P, F, C, M, O (corresponding to the five kinds of wood) or T, meaning total. When theletter is T, there are no integers following it on the line. The program…

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

(This is a better version of an exercise from Chapter 1.) A government research lab has concluded that an artificial sweetener commonly used in diet soda pop causes death in laboratory mice. A friend of yours is desperate to lose weight but cannot give up soda pop. Your friend wants to know how much diet soda pop it is pos- sible to drink without dying as a result. Write a program to supply the answer. The input to the program is the amount of artificial sweetener needed to kill a mouse, the weight of the mouse, and the desired weight of the dieter. Assume that dietsoda contains 1/10th of 1% artificial sweetener. Use a named constant for this fraction. You may want to express the percent as the double value 0.001.
A-Write a program to compute the drag force F, (in Newton) When a body swims through fluid, the drag force is given by 1 F₁ =pV²ACD Take: p= 1000 kg/m3 is the density of fluid, V 1.25 (m/s) is the swimming speed, A=0.25 m² is the frontal area of the body, Cp=0.09 is the coefficient of drag. Matlap
How do I write my computer program that shows the current population at 78,000. And there are 365 days in a year. A baby born every 7 seconds, someone dies every 13 seconds and an one new immigrant every 45 seconds. Print the next 5 years population
