Answer the following statement with TRUE or FALSE: the correct way to implement a sensitivity analysis for the second coefficient of the objective function is to vary not only the second coefficient but also the first one (at the same time).
False
Answer the following statement with TRUE or FALSE: the optimal solution for a company that is able to produce two different products (x1 and x2) is x2 = 0 and x1 = 6. The best strategy for this company is to produce only x2.
False

false
The constraint x1 + x2 ≤ 1 is named as "conditional constraint" in 0-1 integer programming problems.
false

Answer the following statement with TRUE or FALSE: If one of the coefficients of the objective function is changed to a value outside of its respective sensitivity range (greater than the upper limit or lower than the lower limit), the optimal solution will be different than the one originally obtained before the change is implemented.
true
For a "Primal maximization problem" with Z equal to 2,570, its respective "Dual minimization problem " would also have a Z of 2,570.
true
Random numbers are equally likely to occur.
true
Random numbers generated by a mathematical process instead of a physical process are pseudorandom numbers.
true
