Aaron, Bob, and Carl are the proud owners of Three Brothers Motorcycles. During business hours, customersarrive at a rate of 0.49 customers per hour. Business hours are from 8am until 6pm, with a lunch hour from noonuntil 1pm, during which the shop is closed. Let Y be the time (in hours) that passes from 1pm (when they reopenfrom lunch) until the next customer enters the shop.Then Y has an Exponential distribution with parameter A =Do not round. Use 2 decimal places in your answer.

Introduction: It is given that customers arrive at the rate of 0.49 customers per hour.

Answered: Aaron, Bob, and Carl are the proud…

The figure below is a time-series graph showing overall death rates (from all causes) in a country for 1900 to 2015. The spike in 1919 was due to a worldwide epidemic of influenza. Write a few sentences summarizing the overall trend, describing how much the death rate changed over this period of time and putting the 1919 spike into context in terms of its impact on the population.

The death rates have increased by about 30% since the 1920s. The death rate during the influenza epidemic was about half of its current rate. O B. The death rates have decreased by about 50% since the 1920s. The death rate during the influenza epidemic was over four times its current rate. C.

The probability that a student passes an exam is 0.92, given that he studied. The probability that he passes the exam without studying is 0.15. As he is a diligent student, we know that the probability that the student studies for an exam is just 80%. Given the student passed the exam, determine the probability that he studied. Use a calculator to simplify your answer, and round it to three decimal places.
