Answer this question with respect to Test 4 Output posted in Canvas. Which of the following statements is true? If the right hand side of constraint 2 is changed to 102 , the new optimal solution value is 408 . This can be inferred from the dual variable for constraint 2. In the original optimal solution, X1=40 and X2=40. If the right hand side for constraint 2 is changed to 5 and the problem is re-solved, the new optimal solution value is -17 If the right hand side for constraint 2 is changed to 5 and the problem is re-solved, the new optimal solution value is -19 . Answer this question with respect to Test 4 Output posted in Canvas. Which of the following statements is true? The optimal solution value for this problem is -17 and it's a minimization problem.
