Multiple-step cаlculаtiоn prоblem: Pleаse shоw your work to receive full credit. Input the numerical answer in each blank. The Peachtree Airport in Atlanta serves light aircraft. It has a single runway and one air traffic controller to land planes. It takes an airplane 12 minutes to land and clear the runway. Planes arrive at the airport at the rate of 4 per hour. (Assume Poisson processes for both arrivals and services). Determine the average number of planes that will stack up waiting to land. (Round to the nearest 1 decimal place 0.0) [A] Find the average time (in hours) a plane must wait in line before it can land. (Round to the nearest 1 decimal place 0.0) [B] Calculate the average time (in hours) it takes a plane to clear the runway once it has notified the airport that it is in the vicinity and wants to land. (Round to the nearest 1 decimal place 0.0) [C]
Multiple-step cаlculаtiоn prоblem: Pleаse shоw your work to receive full credit. Input the numerical answer in each blank. Suppose a single-server queueing system has a Poisson input at a mean rate of 5 customers per hour. Service time is exponentially distributed with a mean of 10 minutes. Determine the following. The mean number of customers in the system. Round to the nearest whole number. [A] The mean time in the system (in hours). Round to the nearest whole number. [B]
