1 point Scenario B: Suppose you have a four-activity sequential process. Throughput capacities in units per minute are shown in parentheses: Task1(3)Task2(4)Task3(2)>Task4(5) No buffers exist between tasks, so an upstream task must wait if the downstream task is busy. What is the actual throughput rate for the sequential process as a whole (i.e., at what rate would units exit task 4)? Pick the closest answer. .5 1 2 3 4 5 1 point Refer to Scenario B: What would task 1's utilization be? Pick the closest answer. 0% 20% 40% 60% 80% 100%
