Question 4 Not yet answered A single server queuing system with a Poisson arrival rate and exponential service time has an average arrival rate of 10 customers per hour and an average service rate of 12 customers per hour. What is the probability that a customer waits 2 minutes or more in the line? Marked out of 1.00 P Flag question a. 0.1667 O b. 0.2204 O c. 0.7796 O d. 0.8333 Determine which delivery alternative would be most economical for 130 boxes of parts. Each box costs $421 and the annual holding cost is 32% of the cost. Assume 365 days per year. Overnight delivery option costs $300, and eight-day delivery option costs $125 a. The eight-day option is at least $320 cheaper than overnight O b. The overnight option is at least $160 cheaper than eight-day O c. The eight-day option is at least $160 cheaper than overnight O d. The overnight option is at least $320 cheaper than eight-day Customers arrive at a video rental desk at the rate of 11 per minute(Poisson).Each server can handle 3.667 customers per minute(Poisson). There are 4 servers in the system. What is the probability that a customer has to wait for the service? a. 0.127 O b. 0.491 O c. 0.123 O d. 0.509 O e. 0.038
