A project manager must select four analysts from her group to write four different software functions. There are 9 junior and 4 senior analysts in her group. The first and fourth functions can be written by any of the analysts. The second function must be written by a senior person and the third function must be written by a junior person. How many ways are there for her to assign the analysts to the functions if no person can be assigned to more than one function?
Answer:?
Each morning during rush hour, 10,000 people want to travel from New Jersey to New York City. If a person takes the commuter train, the trip lasts 40 minutes. If x thousand people per morningdrive to New York, it takes 20 + 5x minutes to make the trip. This problem illustrates a basic fact of life: If people make their decisions individually, they will cause more congestion than is actually necessary.a. Show that if people make their decisions individually, an average of 4000 people will travel by road from New Jersey to New York. Here you should assume that people will divide up betweenthe trains and roads in a way that makes the average travel time by road equal to the travel time by train. When this “equilibrium” occurs, nobody has an incentive to switch from the road to thetrain or vice versa.b. Show that the average travel time per person is minimized if 2000 people travel by road.

Alexa interacts with users using artificial intelligence and voice recognition. It can be used to perform daily tasks such as making to-do lists, reporting the news and weather, and interacting with other smart devices in the home. In 2018, the Amazon Alexa app was downloaded some 2,800 times per day from the Google Play store.† Assume that the number of downloads per day of the Amazon Alexa app is normally distributed with a mean of 2,800 and standard deviation of 860.arrow_forwardYou may need to use the appropriate appendix table to answer this question.
