An object in a simulation accelerates from a rest speed of 4 meters per second in 2 seconds. it then accelerates linearly for the next 3 seconds until it reaches 10 meters per second. the object remains at that speed (acceleration=0) for 3 seconds and then de-accelerates linearly until it comes to rest 2 seconds later. which graph demonstrates the speed of the object for those 10 seconds?

Using pert, adam munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 21 months, and the project variance is 4. a) what is the probability that the project will be completed in 17 months? b) what is the probability that the project will be completed in 20 months? c) what is the probability that the project will be completed in 23 months? d) what is the probability that the project will be completed in 25 months? e) what is the due date that yields a 95% chance of completion?
