2. You are again working for the census bureau and they need some statistics regarding the distributionof ages. Write a program to read in a number of ages. (You do not know upfront how many entriesyou have, so you need to keep track of it.) Compute the average age and the age that occurs mostfrequently (some of the ages might be the same). Ages should be read in as integers, the averageshould be a real number. Calculate the population standard deviation using the formula:2n.ai/n-(/n)Standard deviation =11

Write an improved version of the futval . py program from Chapter 2.Your program will prompt the user for the amount of the investment, theannualized interest rate, and the number of years of the investment. Theprogram will then output a nicely formatted table that tracks the value ofthe investment year by year. Your output might look something like this: Year Value----------------0 $2000 . 001 $2200 . 002 $2420 . 003 $2662 . 004 $2928 . 205 $3221 . 026 $3542 . 127 $3897 . 43
You are conducting a linguistic study and are interested in finding words that contain the letter 't' or 'T' in the first half of the word (including the middle letter if there is one). Specifically, if the first half of the word does contain a 't' or a 'T', your program should output a 1. If the first half does not contain the letter 't' or 'T', but the second half does, then your program should output a 2. Otherwise, if there is no 't' or 'T' in the word at all, your program's output should be -1. You may assume that the word entered does not have more than 50 letters.
CODE USING C++ Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah". Let's try this out now! Input A line containing two integers separated by a space. 777·7 Output A line containing a string. Jackpot!
C++ Programming Exercise: A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.
You can find out how many seconds have elapsed since Jan 1, 1970 using the time() function. #include <time.h> now = time(NULL); // now is more than a billion seconds (which data type should you use?) Write a program that estimates how many years, months, weeks, days, and hours have gone by since Jan 1 1970 by calculations with the number of seconds that have passed. The number of months must be less than 12, i.e., take out how many years have gone by first, then how many months are left, then weeks, etc. Assume that all years have 365 days, and all months have 30.42 days. Don’t use a calculator, or any web site that reports the number of seconds in a month, etc. – your C program can calculate anything that you need. Notice that this is an assignment on using arithmetic in C. Hints. How many seconds are in a minute? hour? A day? A week? A month? A year?
An oil slick occurs when an underwater refinery pipe ruptures, pumping oil into the water. The spilled oil sits on top of the water and causes a natural disaster. For simplicity, suppose that the oil sits on top of the water in the form of a circle. Write a program that prompts the user to enter the rate at which the ruptured pipe pumps oil (in gallons) per minute, the thickness of the oil on top of the water, and the number of days for which the area is covered by the spilled oil. The program outputs the spilled area (in kilometer) and the volume of oil (in gallons) on top of the water after each day.
(Modify) a. Modify the program you wrote for Exercise 7 to provide the mass of a person as an output, given his or her weight as an input to the program. Use your program to determine the mass of a person who weighs 140 lbf on Earth. b. Modify the program written for Exercise 7a to also output the person’s weight on Mars and the moon. The pull of gravity on Mars is 12.54ft/sec2=3.728m/s2,andonthemoonis5.33ft/sec2=1.625m/s2.
(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.
Use C++ Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. Ex: If the input is: 0 (or less than 0), the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimes
A university recently conducted a survey with regards to demographics and programmes in which students are enrolled. To this end, they asked 15 students the following questions:  In what programme are you enrolled? Responses are C for Civil Engineering, I for ICT, M for Mechanical Eng., P for Process & Utilities. Note that the response could be in any case.  What is your age? Write a C program to input this data for the 15 students and to output (a) the percentage of students who enrolled in ICT, and (b) the percentage of students who are enrolled in Civil Eng. and who are under the age of 30. Use the switch statement in your program.
Use C++ Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: heads tails heads For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to call srand() before each call to rand(). But seeding should only be done once, at the start of the program, after which rand() can be called any number of times. Your program must define and call the following function that returns "heads" or "tails".string HeadsOrTails()
Hi, I need help with the following assignment. Implement a program that reads in a year and outputs the approximate value of a Ferrari 250 GTO in that year. Use the following table that describes the estimated value of a GTO at different times since 1962. Year Value 1962-1964 $18,500 1965-1968 $6,000 1969-1971 $12,000 1972-1975 $48,000 1976-1980 $200,000 1981-1985 $650,000 1986-2012 $35,000,000 2013-2014 $52,000,000
