When a person requests a page from one of their hosted websites, the server must find the page and send it to the person's browser. These requests arrive at the rate of 400 per second. The coefficient of variation of the interarrival times is 2. The processing time for a server is 0.01 second with a coefficient of variation of 1. (Round your answer to 4 decimal places.) On average, how much time does a request take to be filled (i.e., include time waiting for a server and the actual processing by the server)? seconds PA 16-21 (Static) Huduko Inc. offers a number of computer... Huduko Inc. offers a number of computer services. Huduko operates with a utilization of 30 percent. The interarrival time of jobs is 8 milliseconds (0.008 second) with a coefficient of variation of 1.5. On average, there are 20 jobs waiting in the queue to be served and 60 jobs in process (i.e., being processed by a server rather than waiting to be sent to a server for processing). How many servers do they have in this system? servers PA 16-22 (Static) A pediatric practice has five physicians... A pediatric practice has five physicians. Historically, patients were assigned to one physician and these patients always were treated by the same physician. For example, Alice's patients always visited her (for "well visits" and "sick visits") and never interacted with the other physicians. However, the practice has decided to change how it sees patients. Now patients will be seen by whoever is available (i.e., not treating patients). Based on our discussion of queuing theory, which of the following three outcomes is/are likely to occur due to this change? 1. The coefficient of variation of patient interarrival times will increase. ii. The utilization of the physicians will increase. iii. The average number of patients actually with a physician (that is, "inventory in process") will increase I only Oll only O ill only Ol and Il only O I and Ill only Oll and Ill only O All of them (1,1, and III) O None of them (neither I,II, nor III)
