Question 9 The equality lines for the following constraints are shown in the graph below: 2 y -JN cty G 6 A 4 E D 6 7 X a The feasible region is the area represented by the letter ABCDEFG 0 0 0 0 0 0 0. Question 10 Maximize Z = 25x + 45y 2x + 4y 20 3x + y 15 Subject to 2 0 a) Graph the feasible region for the two constraints. Drawing the feasible region requires 3 clicks for each constraint on the graph. Use the first two clicks to draw the line and the third click to select the region satisfying the constraint. 16 14 12 10 2 10 12 Clear All Draw: b) The optimal solution occurs at r = and y = The optimal objective function value Z =Question 11 Which of the following decision-making approaches is most suitable in avoiding the "If only I had chosen.." effect? O Hurwicz @ a = 1.0 O maximin O minimax regret O maximax O EMV approach O sensitivity approach
