Design for flexure a simple span beam 26’ long to carry P_D = 1000# and P_L = 2000# at the center of the span. f’_c = 4,000psi and f_y = 60,000psi. show all work

Determine the necessary sample size for the following examples:

A) A senator wants an estimate of the proportion of the population who support her education views. She wants the estimate to be within .013 of the true proportion. Assume a 95 percent level of confidence.

B) 45 percent of tourists going to Las Vegas go to a concert. The Las Vegas tourism board wants to update this percentage. For the new study, the estimate should be within 2% of the population proportion with a 98 percent confidence level.

This assignment will test your knowledge and skills in C++.

1. Create a class named employee and have the data members of:
   1. Name
   2. ID
   3. Salary
2. Create a class named manager that inherits the employee class and adds the data members:
   1. Managed_Employees (Array of up to 3 employees)
   2. Department
3. Create methods to update each data member in the employee class.
4. Create a method to print out the managed employees sorted by their salary in the manager class. (You can use one of the sorting algorithms we learned)
