A particular project network has two paths through it: Path A and Path B. Path A has an expected completion time of 15 weeks and a variance in completion time of 8 weeks, while Path B has an expected completion time of 16 weeks and a variance in completion time of 4 weeks. What is the probability that this project is going to take more than 18 weeks? a. 62% b. 28% c. 38% d. 100% e. 72% PowerBright must decide between two locations on which to build a new power station to provide 60 megawatt hours of electricity a month. Location A would have a variable cost of $1,000 per megawatt hour and Location B would have a variable cost of $1,500 per megawatt hour. A power station at Location A would also require a fixed cost of $70,000 a month, although an estimate of the monthly fixed cost at Location B has not been made available yet, due to ongoing negotiations with a land owner there. At what fixed cost for Location B would PowerBright be indifferent to the choice of either of these two locations? a. $70,000 b. $10,000 c. $50,000 d. $20,000 e. $40,000
