It is difficult to make a budget that spans several years, because prices are not stable. If your company needs 200 pencils per year, you cannot simply use this year’s price as the cost of pencils 2 years from now. Because of inflation the cost is likely to be higher than it is today. Write a

- In various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (z - mean) z+z3+ *** +zn deviation = mean = n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation (double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input…arrow_forwardImagine you are working for a lumber company, and your employer would like a program that calculates the cost of lumber for a customer order. The company sells pine, fir, cedar, maple, and oak lumber. The lumber is priced by board feet. One board foot equals one square foot that is one inch thick. The price per board foot is given in the following table: Pine 0.89 Fir 1.09 Cedar 2.26 Maple 4.50 Oak 3.10 The lumber is sold in different dimensions (specified in inches of width and height, and feet of length) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4 inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which when divided by 12 = 5.333 board feet). Create a blank c++ Give the customer instructions and then ask the user (customer) to identify the items they wish to purchase by inputting the type of wood, the length, width, & heights of the board, and the number of boards they desire. Allow the user to…arrow_forwardWrite a program that computes the rent in five years and the total rent for one year starting five years from nowarrow_forward
- Your team was asked to program a self-driving car that reaches its destination with minimum travel time. Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car current speed and the distance to the target destination. Assume that both distances and car speed are given.

They are exhibiting this amoeba in a national. conference. They want to know the size of the amoeba at a particular time instant. If a particular month's index is given, write a program to display the amoeba's size. For Example, the size of the amoeba on month 1, 2, 3, 4, 5, 6,... will be 0, 1, 1, 2, 3, 5, 8.... respectively.arrow_forward
- Suppose you have an investment plan where you invest a certain fixed amount every year. Modify futval.py to compute the total accumulation of your investment. The inputs to the program will be the amount to invest each year, the interest rate, and the number of years for the investment. Please step by steparrow_forwardWrite a program that will read an executive's job number, level number, and basic pay and then compute the net salary after withholding income tax. Problem analysis: Gross salary = basic pay + house rent allowance + perks Net salary = Gross salary - income tax. The computation of perks depends on the level, while the income tax depends on the gross salary. The major steps are: 1. Read data. 2. Decide level number and calculate perks. 3. Calculate gross salary. 4. Calculate income tax. 5. Compute net salary. 6. Print the results.

The grade is calculated as: If average is 80 or greater than 80, grade is ‘A’. If average is less than 80 and greater then 50, grade is ‘B’. If average is less than 50 and greater then 33, grade is ‘C’. If average is less than 33, grade is ‘F’arrow_forward
- A supermarket is doing a sales promotion for soft drinks. If one day you buy soft drinks and bring the empty bottles the next day, they exchange each set of K empty bottles for a full one. A customer wants to make the most of this offer and therefore bought several bottles on the first day of the promotion. Now he wants to know how many bottles he will have at the end of the second day of the promotion if he use it to the fullest. Make a program to calculate this. Input The first input line contains integer T (1 ≤ T ≤ 10000), which indicates the number of test cases. In each of the following T lines come two integers N and K (1 ≤ K, N ≤ 10000), respectively the number of soft drinks bought and the number of empty bottles to gain a full. Output For each test case print the number of bottles that the customer will have on the second day, if he makes the most of the offer.arrow_forwardWrite a program that computes taxes for the following schedule. If your status is Single and if the taxable income is over but not over $0 $8,000 $32,000 If your status is Married and if the taxable income is over $0 $16,000 $64,000 $8,000 $32,000 but not over $16,000 $64,000 the tax is 10% $800 + 15% $4,400 + 25% the tax is 10% $1,600 + 15% $8,800 + 25% of the amount over $0 $8,000 $32,000 of the amount over $0 $16,000 $64,000arrow_forwardWrite a program that computes how much a customer has to pay after purchasing two items. Make the lower-priced item half price. If the two items have identical prices, you can make one or the other half price. The price is calculated according to the following rules:• Buy one get one half off promotion: the lower price item is half price.• If the customer is club card member, additional 10% off.• Tax is added. Inputs to the program include:• Two items’ prices• Have club card or not (User enters ‘Y’ or ‘y’ for “yes”; ‘N’ or ‘n’ for “no”)• Tax rate (User enters the percentage as a number; for example, they enter8.25 if the tax rate is 8.25%) Program displays:• Base price - the price before the discounts and taxes• Price after discounts - the price after the buy one get one half off promotionand the member’s discount, if applicable• Total price – the amount of money the customer has to pay (after tax)printed with the precision of 2 decimal digits.
