FestEvents is a concert organizer that is evaluating the installation of portable toilets at an outdoor venue where a concert is going to take place. In particular, it is considering an area of the venue that is far away from the existing restrooms. Assume there will be one single queue to access all the portable toilets in this area and that only one person uses a toilet at a time.   FestEvents estimates that there will be 4 arrivals per minute on average to the toilets, with a standard deviation of the time between arrivals of 15 seconds. The average time a person spends using the toilet is 3.12 minutes with a standard deviation of 2 minutes. Suppose FestEvents installs 20 portable toilets.   a) On average, what fraction of the toilets will be occupied during the event? 

CPU-on-Demand (CPUD) offers real-time high-performance computing services. CPUD owns 7 supercomputers that can be accessed through the Internet. Their customers send jobs that arrive on average every 4 minutes. The standard deviation of the interarrival times is 4 minutes. Executing each job takes on average 16 minutes on one of the supercomputers (during this time, the computer cannot perform any other work). The standard deviation of this processing time is 24 minutes.   a) What is the utilization (as a %) of the supercomputers?

You will have 1 hour and 15 minutes (75 minutes; shown in the upper right corner of your screen) to work on the exam; starting from when the questions first load.  You will be unable to make any more changes after 75 minutes from the time you start the exam AND you will be unable to start the exam after 11:59 pm (end of the day) on Thursday, Oct 31. If you lose internet access, the timer will not stop, so you will still only have 75 minutes from when you started before your exam will be over. If your normal internet connection is unreliable, please find a different place to work. You could bring your laptop to campus and use Normandale’s internet OR you could use one of the computers in Normandale’s computer labs. If you plan to work from a different location, TRY IT FIRST with the Pre-Exam Agreement, especially if it will not be at Normandale (since you will need to download Honorlock and have access to a webcam.)  Which of the following is true? (Choose any/all correct answers.)
