WebApr 22, 2024 · Answer: The utilization factor (u) is 75%, the right answer is B. Explanation: According to the given data, we have the following: Arrival rate, a = 6 per hour Service rate, s = 8 per hour Therefore, in order to calculate the utilization factor (u), we would have to use the following formula: Utilization, u = arrival rate/service rate = 6/8 = 0.75 heat network partnership scotlandWebRound to a minimum of 4 decimal places, if necessary.
