Question:
UP Fitness will install 3 new “trapezoidal gel-resistance toners” (“trappy” for short), the latest exercise gadget, specifically designed to contour upper back muscles. Clients who want to use these machines arrive at the rate of 72 per hour. The coefficient of variation of the inter-arrival times is 3. If all three machines are busy, UP Fitness clients use other pieces of equipment, waiting for one of the trappies to become available. The trappy experience is intense – 120 seconds of explosive exercise intensity. The standard deviation of the usage times (measured in seconds) is somewhat small – only 60 seconds. On average, how many UP Fitness clients are waiting to use a trappy?--Please show formulas
