Transcribed Image Text:**Question:**
Suppose that you are using the four-period weighted moving average forecasting method to forecast sales and you know that sales will be decreasing every period for the foreseeable future. What of the following would be the best set of weights to use (listed in order from the most recent period to four periods ago, respectively)?
**Options:**
- A. 0.25, 0.25, 0.25, 0.25
- B. 0.10, 0.20, 0.30, 0.40
- C. 1.00, 0.00, 0.00, 0.00
- D. 0.40, 0.30, 0.20, 0.10
- E. 0.00, 0.00, 0.00, 1.00
**Explanation:**
In contexts where recent trends are expected to continue, it is essential to place more weight on the most current observations. Given that sales are expected to decrease, weights should prioritize the most recent period.

"Activity D on a CPM network has predecessors B and C, and has successor F. D has duration 6. B's earliest finish is 18, while C's is 20. F's late start is 26. Which of the following is definitely true?
- A. B is a critical activity.
- B. D is critical, and has a slack of two days.
- C. C is completed before B.
- D. F is critical, and has zero slack.
- E. D has no slack but is not critical."
**Explanation:**
The image contains a multiple-choice question related to Critical Path Method (CPM) network analysis. There are no graphs or diagrams present; only textual information is provided. The question asks you to determine which statement regarding the sequence and timing of activities in a project is definitely true given the specified conditions of the activities' durations and scheduling constraints.
