- Task 2: Multiply of two fractions The formula to find the Multiply of two fractions is: 6a 4a+20 Multiply: 3a +15 2a² Write a program that ask user to enter (a) for the numerator and denominator of each fraction and displays the Multiply in fractional form.arrow_forwardPeriodic compounding The total accumulated value, including the principal sum P, is given by the formula: where: nt A = P(1 + 1) "² n A is the final amount Accumulated Value P is the original principal sum r is the nominal annual interest rate n is the compounding frequency t is the overall length of time the interest is applied (expressed using the same time units as r, usually years). Using the above formula write a program that will display the following table. Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value 1000 6.00% 10 3.20% 15 2000 3000 9.25% 10 2 ** 3 8 | You must use exponent operator to compute P Exponent Operator in Python is ** Examples m=3 n=2 p= m **n (https://en.wikipedia.org/wiki/Compound_interest) 1 2 4 base = 2 exp = 4 a = base ** exp print(a) 16 print("Solving the exponent, we get Solving the exponent, we get 9 ,p ) 1790.85 3219.89 7486.33arrow_forwardfloat variables are called single precision variables Select one: O True O False 17arrow_forward

This is the formula for calculating the value, v, of the nth term: v=a+(n1)d a is the first number in the sequence. d is the difference between any two numbers in the sequence.arrow_forward(Conversion) Write an assignment statement to convert temperature in degrees Fahrenheit to degrees Celsius. The formula for this conversion is Celsius=5/9(Fahrenheit32).arrow_forward
- (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_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forwardA structure that allows repeated execution of a block of statements is a(n) _____________. sequence selection array looparrow_forward
