It costs $3000 to reserve the room, hire the instructor, bring in the equipment, and advertise. Assume it costs $25 per student for the organizers to provide the course materials. How many students would have to attend for the company to break even? 23 2. Which of the following will increase the breakeven point? A Increase selling price B. Increase fixed cost Decrease variable cost D. Decrease fixed cost A mini project consists of 4 activities A, B, C, and D. Suppose A must be completed before B can start, B must be completed before C can start, and C must be completed before D can start. Which activities are on the critical path? . . CD All A, B, C 4. If P(AB) = 4, then P(BA) = 6 P(A)*P(B) = 4 P(A) P(B) = 4 None of the alternatives is correct A 22 VULL HODUL HALL HADDLE EEE E T Caption... Emphasis Heading 1 11 Normal Strong Paragraph Styles 5. A project consists of 150 jobs and the expected time for each job is given in days. The project only has three paths through it, called A, B and C, and the duration of path A is four days shorter than path B, but equal to the duration of path C. In order to finish the project one day early, the completion time should be reduced one day for each of the three paths. B. path A only C. path A and C only. D. path B only A. 6. Larger values of the standard deviation result in a normal curve that is A shifted to the right B. shifted to the left C narrower and more peaked D.. wider and flatter 7. For a maximization problem, the conservative approach is often referred to as the A minimax approach B. maximin approach C maximax approach D m inimin approach 8. The manager of a manufacturing company is trying to figure out how many products need to be produced for the coming quarter. Suppose the beginning inventory of the quarter is 800 units and the management predicts that the sales volume in the coming quarter would be 3200 units. The company also requires 1500 units ending inventory for the coming quarter. What should be the production volume for that quarter? A. 2400 B 3200 C 3900 4700 CE B 20 JO 1 Paragraph DY D 4700 9. A solution that satisfies all the constraints of a linear programming problem except the nonnegativity constraints is called A optimal B. feasible. C infeasible. D. semi-feasible. asible. 10. In the classic Economic Order Quantity (E0Q) associated with inventory under the assumptions of constant demand, what happens if the holding cost per unit increases from $10 to $20? A. The EOQ increases and the reorder point increases. B.' The EOQ decreases and the reorder point decreases. The EOQ decreases and the reorder point remains the same. The EOQ decreases and the reorder point inoreases. : 9 A A Aa 1 * ADA 2 - c l | c| c] 1 Caption... Emphasis Heading 1 1 Normal Strong ! Paragraph ont Styles 11.
