write a program that prompts the user to input the ages of 4 friends. the program should allow the user to input these ages,find and print the average age using suitable labels.


(Repetition structure, while loop)



You are to write a program in C++ that will perform several conversions. The program should display a menu that will have the following options:


1. Convert Kilobytes to Megabytes.



2. Convert Megabytes to Gigabytes.



3. Convert Gigabyte to Terabytes.



4. Quit.



The program should receive the amount to convert to a specific unit and return the result of that conversion. The program should run several times until the user decides to quit it. Make sure that the program is well indented, free of bugs and logical errors.

A customer in a store is purchasing five items. Design a pseudo code argorithm that asks for the price of each item, and then displays the subtotal of the sale, the amount of sales tax, and the total. Assume sales tax is 6%

Some algorithms used in Artificial Intelligence can be differentiated as white-box and black-box machine learning algorithms. The former are those algorithms that provide results that are understandable for experts in the domain whereas the latter can hardly be understood even by domain experts.

Requirement: Read the relevant literature and suggest how the present black-box machine learning algorithms can be made transparent, interpretable and explainable.

Draw a flowchart that will asks for the amount purchased by the customer. If the customer purchases more than 2,000 then 5%discount is given, Display net amount to be paid by the custom


Consider now the function f(x) = x^4-2x^3− 12x^2 + 16x − 4 which has four distinct roots.



Question 10


Choose the appropriate option:



(1) The secant method and Muller’s method are similar in the sense that they both start with two


points.



(2) The regula falsi and the secant methods are the same and convergence for the regula falsi is


guaranteed because the next approximation is bracketed.



(3) Muller’s method determines the next approximation by considering the intersection of a parabola


and the x-axis through three given points.



(4) Statements (2) and (3) are correct.



(5) none of the above statements

Consider now the function f(x) = x^4−2x^3 − 12x^2 + 16x − 4 which has four distinct roots.



Question 8


Which of the following options is FALSE?


(1) f'(x) has a local minimum at 2.



(2) f'(x) has a local maximum at −1.



(3) f(x) has no singularities and no obvious symmetries and the y-intercept is −4.



(4) f"(x) has a local maximum at x = 0.5.



(5) the two zeros of f"(x) are −1 and 2.





Question 9


Which of the following results is FALSE when applying the various methods as indicated:



(1) p = 0.88338140 when applying the secant method with starting points p0 = 0 and p1 = 1.



(2) p = 0.34170924 when applying the bisection method with the starting points p0 = 0 and p1 = 1.



(3) p = 0.34170924 when applying Newton’s method with starting point p0 = 0.



(4) p = 0.88338140 when applying Muller’s method with starting points p2 = 0, p0 = 1 and p1 = 5.



(5) p = 4.04823531 when applying the regula falsi method with starting points p0 = 1 and p1 = 5.

(For Questions 6 to 7 )


Consider the nonlinear equation sin x − e


−x = 0, which has a roots in the intervals [0, 1], [3, 4] and


[6, 7].



Question 7


Consider again the nonlinear equation sin x − e


−x = 0. Applying the regula falsi method, with


starting point p0 = 3 and p1 = 4 and a tolerance of 10−5 yields the following result :



(1) 0.589117 after at least three iterations



(2) 0.588641 after at most three iteration



(3) The method does not converge to a solution.



(4) 3.096308 after exactly three iterations



(5) None of the above is true.


Consider now the function f(x) = x


4 − 2x


3 − 12x


2 + 16x − 4 which has four distinct roots.
