$.$ True or False $($Mark $"\sqrt[\phantom{2}]{?}"$ when you think the statement is true, otherwise

use $"x",2$ points for each question, $2**5=10$ points in total$)$

Each constraint boundary is a line that forms the boundary of what is

permitted by the corresponding constraint. The points of intersection are $()$

the corner$-$point solutions of the problem.

The number of nonbasic variables equals the total number of variables

minus the number of functional constraints

The coefficients in the objective function of the primal problem are the

right$-$hand sides of the functional constraints in the dual problem.

Sensitive parameters are the parameters whose values can be changed

without changing the optimal solution.

Graphical method for linear programming can be used to solve any

linear programming problem with any decision variables.
