UNUL QUESTION 10 You solved an LP model to determine the optimal product mix that maximizes a manufacturer's profit. You solved the model and found that the optimal solution is to make 12 units of product 1, 17 units of product 2 and 21 units of product 3. One of your constraints was 3P1 +4P2 + 6P3 S 560 P1, P2, P3 are the number of units of cach product to make What is the lack of this constraint? QUESTION 11 In the Forward and Backward passes that we do to determine the Early Start (ES), Early Finish (EF), Late Start (LS) and Late Finish (LF) of the activities, which one of the following statements is FALSE? To start the backward pass, we set LF of the ending nodo equal to its ES To start the forward pass, we set es of the starting node equal to nero The EF of an activity is equal to the Es of this activity plus its duration The LS of an activity is equal to the LF of this activity minus its duration SHU U HUE HUHI THIU LCH 4 An Ht HHHV UHD MacBook Air
