A project has 12 activities: A through L(A,B,C,D,E,F,G,H,I,J,K, and L). This project has two critical paths: A-B-C-D-G-Land A-E-F-H-I-L. Which one of the following activities can have slack greater than zero? G none of the choices are correct K Question 14 (4 points) Cars arrive at a toll booth at a rate of 21 per hour and the toll collector can serve 27 cars per hour on average. Calculate the average number of cars in the system. [Select the appropriate range in which your answer falls.] More than 0 but less than or equal to 1.0 More than 1.0 but less than or equal to 2.0 More than 2.0 but less than or equal to 3.0 More than 3.0 but less than or equal to 4.0 More than 4.0 Project X and project Y have the same number of activities ( 500 activities each). Project X has 25 critical paths and project Y has 3 critical paths through the network. As a result, project X has several more activities in the critical paths than that of project Y. Which project will most likely be harder to manage (i.e., completing the project on-time by the due date) for the project manager? Project Y Project x
