Consider the following problem formulation, original tableau, and optimal tableau. Max Z = X1 + 3 X2 s. t. X1 + 2 X2 9 X1 +4 X2 11 X1, X2 0 Original Tableau Z X1 X2 S1 S2 RHS 1 -1 -3 0 00 01 21 0 9 0 1 4 0 1 11 Optimal Tableau Z X1 X2 S1 S2 RHS 100 1/2 1/2 10 01 0 2 -1 7 0 0 1 -1/2 1/2 1 *Note: Make sure you can see the entire image. The last column should be RHS. 1. The matrix B resulting from BV is: O[1,-3,-4 0,3,2 0,1,4] O[1,0,0 0,1,0 0,0,1] OAnswer not provided O[1,-3,-1 0,2,1 0,4,1] O[1,-1,-3 0,1,2 0,1,4] O[1,-3,-4 0,4,1 0,1,3] For questions 2,3, and 4: To determine the range of values for which limits on the X1's objectives function coefficient will not change the basis of the optimal solution: 2. Where do we need to introduce a variable delta to calculate the allowable range? OAnswer not provided OBV's first row, X1 column OBV's first row, Column 1 ORow 1 of RHS ORow 2 of RHS 3. Select the mathematical operation(s) that will allow you to find the allowable ranges of values for delta. OB^-1 OB^-1*RHS and B^-1 OB^-1*NBV OAnswer not provided OB^-1 * RHS OB^-1*NBV and B^-1 4. Determine X1's objectives function coefficient allowable range that will not change the basis of the optimal solution, enter the range next: OBetween -1 and 1 OAnswer not provided OBetween 4/3 and 16 OBetween 2 and 12 OBetween 0.75 and 1.5 OBetween 6 and 11 O%50%Between -0.25 and 0.5 OBetween -2 and 3.5
