Use this data for the exercises that follow: In 2013, there were roughly 317 million citizens in the United States, and about 40 million were elderly (aged 65 and over).[34] 60. It is predicted that by 2030, one in five U.S. citizens will be elderly. How much greater will the chances of meeting an elderly person be at that time? What policy changes do you foresee if these statistics hold true?
An average of 40 jobs/day arrive at a factory; and the factory can process an average of 45jobs/day. Assume that both the inter arrival and process times are exponentially distributed. A. Find the probability that exactly 180 jobs arrive at the factory in a 5-day periodB. Measuring from the time a job arrives at a factory, on the average how long does it takebefore the job is completed?C. What fraction of the time is the factory idle?
On average, 40 jobs arrive per day at a factory. The time between arrivals of jobs is exponentially distributed. The factory can process an average of 42 jobs per day, and the time to process a job is exponentially distributed. a. On average, how long does it take before a job is completed (measured from the time the job arrives at the factory)? b. What fraction of the time is the factory idle? c. What is the probability that work on a job will begin within two days of its arrival at the factory?
