Wizard, a popular brand of electric garage door opener, includes two 40-watt bulbs that go onwhen the garage door is opened. A bulb will generally last about one year in normal operation.Three neighbors, James, Smith, and Walker, each has a Wizard opener in their respectivegarages. Each time a bulb burns out, James replaces both bulbs. Smith, on the other hand, replaces only the bulb that has burned out, and Walker replaces both bulbs only after both haveburned out. Assume that light bulbs fail according to an exponential law.b. What percentage of the time will Walker have only one bulb burning?

Assume that light bulbs fail according to an exponential law.c. Is there any advantage of James’s strategy over Smith’s?

Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration.

The model is created first because a simulation needs models to run. They are created at the same time because they are pretty much the same thing. The two are unrelated and can be created in any order. Simulation should come first because the model can only be developed using simulation.arrow_forward
- Six thousand light bulbs light a large hotel and casino marquee. Each bulb fails completely at random, and each has an average lifetime of 3,280 hours. Assuming that the marquee stays lit continuously and bulbs that burn out are replaced immediately, how many replacements must be made each year on the average?arrow_forwardA robbery has just been committed at the Corner Market in the downtown area of the city (black rectangle in the city map). The market owner was able to activate the alarm, and the robber fled on foot. Police officers arrived a few minutes later and asked the owner, "How long ago did the robber leave?" "He left only a few minutes ago," the store owner responded. "He's probably ten blocks away by now", one of the officers said to the other. "Not likely," said the store owner. "He was so stoned on drugs that I bet even if he run ten blocks, he's still only within a few blocks of here! He's probably just running in circles!"Perform a simulation experiment that will test the store owner's hypothesis. Assume that at each corner of a city block there is an equal chance that the robber will go in any one of the four possible directions, north, south, east or west. Simulate for ten steps and five trials, and then indicate in how many of the trials the robber is within three blocks of the store.arrow_forwardOne player is assigned the number 10 and another player is assigned the number 5.

The department believes that an employee’s time is worth $15 per hour. The slow copier rents for $4 per hour, and it takes an employee an average of 10 minutes to complete copying. The fast copier rents for $15 per hour, and it takes an employee an average of six minutes to complete copying. On average, four employees per hour need to use the copying machine. (Assume the copying times and interarrival times to the copying machine are exponentially distributed.)
