Nick, and Oscar; Diane is willing to marry Jason, Larry, Nick, and Oscar; and Elizabeth is willing to marry Jason and Matt.
a) Model the possible marriages on the island using a bipartite graph.
b) Find a matching of the young women and the young men on the island such that each young woman is matched with a young man whom she is willing to marry.
c) Is the matching you found in part (b) a complete matching? Is it a maximum matching?

- Although Pythagoras preceded William Shakespeare by 2,000 years, the philosophy of the Pythagoreans is mentioned in Shakespears The Merchant of Venice. Here is a quote from that play: Thou almost makst me waver in my faith, To hold opinion will Pythagoras, That souls of animals infuse themselves Into the trunks of men. Research the Pythagoreans. What were the main beliefs held by their society? What part of the philosophy of the Pythagoreans was Shakespeare referring to specifically with this quote? What present-day religions share a similar belief?

- No need for thorough Explanation. The research department of a five-star hotel conducted a survey. It found that among 2230 guests, 1540 tip the front desk officers, 1192 tip the bellboys, 938 tip the maids, 250 tip the maids and the bellboys, 710 tip the front desk officers and the maids, 735 tip the front desk officers and the bellboys, 195 tip all the three personnel. How many of the surveyed guests tip exactly two of the three services? How many of the surveyed guests tip only the front desk officers? How many of the surveyed guests tip only the three services? How many of the guests do not give tip to any of the services? How many of the surveyed guests tip at least two of the three services?arrow_forwardImagine a game show on television where one lucky contestant is presented with three upside-down buckets that are numbered 1, 2, and 3. Under one of the buckets is a five-ounce gold bar. Under each of the other two buckets is a lump of coal. After the game ends, the contestant receives what is under his or her bucket. The host of the game show asks the contestant to choose one of the three buckets. After the contestant makes a choice, the host lifts up one of the remaining two buckets to reveal a lump of coal under it. At this point, only two buckets remain uncovered: the bucket that the contestant originally chose and the bucket that was not uncovered by the host. The host subsequently asks the contestant if he or she would like to keep the original bucket or change buckets to the only other bucket remaining. 1. If the contestant does not change buckets and stays with the original bucket chosen, what is the probability that the contestant will win the five-ounce gold bar?

(Hint: Draw a sketch. Assume each route can pass through a city at most one time.) (a) How many routes from North Point to Star Lake pass through Beaver Dam? To answer this question, think of creating a route from North Point to Star Lake that passes through Beaver Dam as a 3-step process. Step 1: Choose a route from North Point to Select- Step 2: Choose a route from-Select- v to Beaver Dam. Step 3: Choose a route from Beaver Dam to Star Lake. There are choices for step 1, choices for step 2, and choices for step 3. Thus, the answer is (b) How many routes from North Point to Star Lake bypass Beaver Dam?arrow_forward3. Three men and three women were nominated for THREE positions on the school board. Suppose the three male are named A, B, and C, and the female are named D, E, and F. Further, suppose that the following statements are true: • There should be at least one male and at least one female to be selected; If A won a position, so did D; • If neither C nor F won a position, then E did not win a position; If A did not win a position, then both D and E won positions; • C cannot be the only male candidate to be selected; • Either E or F (or both) would win a position. There is only one way to choose three candidates to satisfy all criteria above. Please find that way and justify it to be the only valid choice.arrow_forward
