Chapter 3.2, Problem 87E

World Population One projection of the world population by the United Nations (a low-projection scenario) is given in the table below. The data can be modeled by y = − 0.36 x 2 + 38.52 x + 5822.86 million people, where x is the number of years after 1990. In what year after 1990 does this model predict the world population will first reach 6,702,000,000?

Year Projected Population (millions)
1995 5666
2000 6028
2025 7275
2050 7343
2075 6402

Please solve the following Probability Problem, please show all work and solve what is asked: HW 1.w. (Special game)The atmosphere has heated up and a fight erupted! There are n + 1players and somebody threw the first punch. Once a person is punched,they punch another person in the group at random. What are the oddsthat after m iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?Now take it up a notch: imagine the first person punched N other peopleat random, and once someone gets punched, they punch another N peoplein the group at random, and so on. Again, what are the odds that afterm iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?
