Consider the following LP problem with two constraints: 23X + 44Y >= 1012 and 15X + 21Y >= 315. The objective function is Max 15X + 44Y. What combination of X and Y will yield the optimum solution for this problem? . unbounded problem O b. 18, 2.14286 . , 15 Od infeasible problem O e 21,0 Construct the appropriate control chart for the 11 observations, and determine if the process is in control using two sigma limits. No. of defects per unit for the observations are: 11, 4, 2, 1, 5, 8, 11, 7, 5, 6, 11. O a. 3 observations out of control O b. 2 observations out of control O c. 1 observations out of control Od. Under control
