true/ false

1)Sunk costs will not impact the objective function co-efficients of the changing cells in LP Solver.

2)Remembering how to solve two equations with two unknowns is a good rationalization for learning to solve Linear Programming models graphically.

3)The LP Solver error message "The set target cell values do not converge" occurs because of infeasibility.

4)A sensitivity report is an important part of Integer Programming.

5)If a person wanted to choose exactly one of two choices (such as choosing between two store purchase alternatives), this is modelled in Excel's LP Solver by settingthe Variable Cells as binary and have them sum to less than or equal to 1

6)Let X₁, X₂ and X₃ represent binary decision variables, where the subscript indicates the project number. The following equation represents the constraint that project 3 cannot be performed when both project 1 and project 2 are performed:

X₁ + X₂ 2 (1 - X₃)

7)Let X₁, X₂ and X₃ represent binary decision variables, where the subscript indicates the project number. The following equation represents the constraint that project 3 needs to be performed when either project 1 or project 2 (or both) is performed:

X₁ + X₂ 2 X₃
