Alex, Bob, Carol and Daniel must cross a rickety bridge at night before next morning; they all beginon the same side. It is known that an explosion is very likely to happen any time after 51 minutes.They have one flashlight. A maximum of two people can cross the bridge at one time. Any party thatcrosses, either one or two people, must have the flashlight with them. The flashlight must be walkedback and forth by a person until all of them cross to the other end. Alex takes 3 minutes to cross thebridge, Bob takes 6 minutes, Carol takes 10 minutes, and Daniel takes 30 minutes. A pair must walktogether at the slower person's pace. Find a way to get all of themto cross the bridge. In your answer,you must show how they cross the bridge using the most suitable notations from the lecture notes(Unit 2) and you must also show the time taken for each crossing.

An application runs two different types of advertisements, "long ads" and "short ads". A long ad costs a company 25 cents each time it is run and a short ad costs a company 17 cents each time it is run. If an advertiser ran a total of 492 long and short ads and it cost them $107.64, how many long ads did they run?
A shoe company wants to determine if the new tread on its top line of running shoes lasts longer than the original tread. The company recruits 50 runners for a study. Each runner will perform their typical workout wearing one shoe with the original tread on one foot and another shoe with the new tread on the other foot. The foot that wears the new type of tread will be decided by flipping a coin. After one month, the runner will wear the new type of tread on the opposite foot. At the end of the second month, the difference in tread wear (New - Original) will be calculated. What type of sampling is described in this study? What is the appropriate inference procedure? one-sample t-test for μ one-sample z-test for p one-sample t-test for diff two-sample t-test for new original
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Noah sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 12 visitors purchased no costume. 193 visitors purchased exactly one costume. 19 visitors purchased more than one costume. If next week, he is expecting 400 visitors, about how many would you expect to buy exactly one costume? Round your answer to the nearest whole number.
An emergency vehicle can take one of two routes from a given site to the hospital immediately after a strong rainstorm. The region is crossed by creeks that tend to flood during rainstorm events. Route A would take 20 minutes, but it has four creek intersections where the road can flood, and each time that the emergency vehicle needs to cross a flooded road there is a 5-minute delay. Route B is longer and would take 35 minutes, but it has only two creek intersections where the road can flood. Assume that the probability of flooding after the rainstorm event at any of those creek
