A programmer notices that the following code snippet uses the same algorithm forcomputing cost after taxes, but with different variables, in the two places as shownbelow, and in several other places in the program. What could be done to improvethe program?final double TAXRATE1 =final double TAXRATE2 = 5.5;double subtotal = price (1 + TAXRATE1) / 100;10;double total= subtotal + shipping *(1 + TAXRATE2) / 100;Declare the tax rates as variables, not constants.Define a method that looks up tax rates for goods and shipping charges.Define a method that computes the cost after taxes from arguments for the costbefore taxes and the tax rate.Define a method that prompts the user for an amount and a tax rate, thenreturns the total amount including the tax.

ANSWER:Define a function that computes the interest earned from an amount and a rate of interest.

What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)? Use a Monte Carlo Simulation and a frequency table to write a program that calculates this probability, where the number of people (x) in the simulated class is given by the user. The probability for a class of size 23, should be right around 50%. PLEASE use the code outline given below to answer this question: import mathimport random # create and initialize frequency table:ft = []k = 0while(k < 365) : ft.append(0) k = k+1 # Allow the user to determine class size:print("Please type in how many people are in the class: ")x= int(input()) success = 0 # Simulate:c = 0while(c < 10000) : # Step 1: re-initialize birthday frequency table (it must be re-initialized for each play-through (why?): k = 0 while(k < 365) : ft[k] = 0 k = k+1 # Step 2: randomly get x birthdays and update frequency table: k = 0 while(k < x): # your code…
Let's modify the program from this section so that the user can supply the interest rate. For very small interest rates, it may take a very long time for the balance to double. Assume the user can't wait for more than twenty years. Stop adding interest when the balance has doubled or twenty years have elapsed. 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 finaldoubleTARGET=2*INITIAL_BALANCE; doublebalance=INITIAL_BALANCE; intyear=0; Scannerin=newScanner(System.in); System.out.print("Interest rate in percent: "); doublerate=in.nextDouble(); // TODO: Count the years required for the investment to double // but no more than 20 years /* Your code goes here */ System.out.println("Year: "+year); System.out.printf("Balance: %.2f%n", balance); }

hi! i am a newbie in python. please help me on this problem. also, please send a screenshot for a proof that the codes works. thanks~
The body mass index, BMI, is a measure used to determine if a person is overweight or not. We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greater
This software has me a little perplexed as to where to begin. Is it possible that the information I'm receiving is causing me confusion? I don't know for sure. The program must be written in pseudocode. "Seating is divided into three parts in a theater. Section A tickets cost $20 each, section B seats cost $15 each, and section C seats cost $10 each, according to the price list. Three sections of seating are available: Section A has 300 seats, 500 seats, and 200 seats. For each section, design a program that asks for the number of tickets sold, and then displays the total amount of money earned from ticket sales for each part. The numbers in each part should be checked by the software." Assuming I'm correct, I'm not sure where to begin the software. I'm not sure what variables to declare or whether I even need to declare any before the "While" loop if any are required.
Please find the running time of the program below. See attached photo for example. int exam_1(int n) { int i, j, k, sum = 0; for(i=3; i<=n * 3; i+=3) { for(j=1; j<=n; j++) { for(k=2; k<=j; k* =2) { sum = sum + k * i; if(sum > j) { sum = sum + 1; } } } }}
Write a program that reads student scores, gets the best score, andthen assigns grades based on the following scheme:Grade is A if score is ≥ best -5Grade is B if score is ≥best -10;Grade is C if score is ≥best -15;Grade is D if score is ≥best -20;Grade is F otherwise.The program prompts the user to enter the total number of students, and thenprompts the user to enter all of the scores, and concludes by displaying the grades.Here is a sample run: Enter the number of students: 4 ↵EnterEnter 4 scores: 40 55 70 58 ↵EnterStudent 0 score is 40 and grade is FStudent 1 score is 55 and grade is CStudent 2 score is 70 and grade is AStudent 3 score is 58 and grade is C
You are working as a teaching assistant at a local university, you gave your students a mathematics exam. The test result appears in as shown in table (1) below. The head of the department asked to write the code that accomplishes the following three tasks using Matlab: Table (1): show the test result for a mathematics exam Number of 1 2 3 4 5 8 9. student Grades 35 50 70 63 66 90 30 27 89 aUniversity 1. Draw the flowchart for the previously requested tasks and the two that follow. 2. The number of students who got greater than or equal to 50. 3. If the mark is greater than or equal to 50, then the output is “pass" otherwise the output is "fail" 4. The number of even marks and the number of odd marks.
Please answer it in Python Offer a program that knows how to find the solution of the jackpot price game in a way effective. it's up to you to choose a number at random, and it's up to your program. to guess it. You must write him 'g' if the number he guessed is too large, 'p' if the number is too small and 'b' if he guessed the right number. The number of trials is not limited. The program should always be able to guess the right number fast enough Example 1: Think of a number and I'll try to guess! Ready? Press Enter... Hmm.. Is it 15? p Hmm.. Is it 35? g Hmm.. Is it 31? g Hmm.. Is it 24? g Hmm.. Is it 20? g Hmm.. Is it 19? g Hmm.. Is it 17? p Hmm.. Is it 18? b I won! Example 2: Think of a number and I'll try to guess! Ready? Press Enter... Hmm.. Is it 4? p Hmm.. Is it 69? g Hmm.. Is it 49? g Hmm.. Is it 7? p Hmm.. Is it 19? p Hmm.. Is it 38? g Hmm.. Is it 25? g Hmm.. Is it 20? b I won! Example 3: Think of a number and I'll try to guess!
