- Table 2 shows a recent graduate’s credit card balance each month after graduation. a. Use exponential regression to fit a model to these data. b. If spending continues at this rate, what will the graduate’s credit card debt be one year after graduating?Recent data suggests that, as of 2013, the rate of growth predicted by Moore’s Law no longer holds. Growth has slowed to a doubling time of approximately three years. Find the new function that takes that longer doubling time into account.The analysis of tooth shrinkage byC. Loring Brace and colleagues at the University of Michigan’s Museum of Anthropology indicates that human tooth size is continuingto decrease and that the evolutionary process has not yetcome to a halt. In northern Europeans, for example, tooth sizereduction now has a rate of 1% per 1000 years. What will be our descendants’ tooth size 20,000 years from now (as a percentage of our present tooth size)?
- It is known to show an exponential distribution where the average lifespan of a type of CPU is ten years. What is the probability that the company that leases the server for ten years will encounter a central processing unit failure within the period of use?It is known to show an exponential distribution where the average lifespan of a type of CPU is seven years. What is the probability that the company that leases the server for five years will encounter a central processing unit failure within the period of use?It is known to show an exponential distribution where the average lifespan of a type of CPU is nine years. What is the probability that the company that leases the server for six years will encounter a central processing unit failure within the period of use?
- It is known to show an exponential distribution where the average lifespan of a type of CPU is eight years. What is the probability that the company that leases the server for five years will encounter a central processing unit failure within the period of use?A five years Business Informatics student studying at TU Wien does some temporary substitute work on the banking sector every 31 days on average, and this time follows an exponential distribution. After acquiring one of these works, its duration is also aleatoric, exponentially distributed and its mean duration is 60 daysThe money earned depends on the total number of days worked in each contract, paid at $100 daily. For unemployment periods, the student has taken out an insurance for which $50 is paid for each day on the dole. Build a queuing model to establish the mean annual income (1 year = 365 days) that the student earns. (Hint: single server, finite customer population of 1.)If the national economy shrank at an annual rate of 6% per year for three consecutive years, then the economy shrank by 18% over the three-year period. The statement is false because each year is a different reference value. The economy actually shrank ____ % over the three-year period.
- the data contained in the datafile named crudecost shows the U.S. refiner acquisition cost of crude oil in dollars per barrel (energy information administration website,February 3, 2014).a. construct a time series plot. What type of pattern exists in the data?A production plant has three machines and the two products move about among these three machines. Upon completion of the process at machine i, it moves to the next available machine out of the two remaining machines. Therefore, there are always two busy machines. If the service times of these machines follow an exponential distribution with a rate of μ1=2/min, μ2=1 /min, μ3=4 /min, respectively, what proportion of time machine 1 will be idle?For each data series, (you can creat graph with year on x axis and data series on y axis to visually see if it appear stationary or not) carefully describe what appears to be happening over the period from 1982 to 2022, and why you think it is happening. Base your answer upon your knowledge of statistics and agriculture, along with common sense. If you are not entirely sure what is happening. In some cases what is happening in one graph may affect what you see in another.
