Create a C++ program that meets the following requirements:
1. It is necessary to read TotalUnits and ratePerUnit.
2. The computeTuition function will return the totalTuition based on the input parameters.There are two parameters: totalUnits and ratePerUnit.
3. Function computeFamilyDiscount – this function computes a 5% family discount.Let x denote the number of biased die with the following probability mass function p(x)
X: 1 2 3 4 5 6
P(x): 1/6 1/6 1/5 y 1/5 1/6
a) find the value of y
b) find the cdf of x

1. Solve the exact differential equation (𝗑 − 2𝑒𝑦)𝑑𝑦 + (𝑦 + 𝗑 sin 𝗑)𝑑𝗑 = 0.
2. Solve the differential equation 𝗑 𝑑𝑦 + 2𝑦 = 𝗑4.
a. Create a class called Rectangle with data members: width, length and area. The class should have functions to allow for setting of both length and width, calculate the area, and retrieve the width, length and area. (13 marks)
b. Write a main function that declares an object from the class above, and use the methods in that class to input the length and width, calculate the area and, retrieve and display those values (width, length and area).
A proposed system intends to store the student data (Student Number, Student Name and Phone Number) and also allow for the access of the same data. The data should be hidden and not prone to direct manipulation. The data is read and written using methods.
Required:
(i) Create a class called Student for the above scenario in C++ (6 marks)
(ii) Write a main function in the same C++ program to instantiate an object from the class Student, and allow for student data to be inputted though the keyboard and then display that student data.
