The U. S. Bureau of the Census predicted that the population of Pennsylvania would be about 12.7 million in 2010 and then would increase by about 0.24 million per year until 2018. Which of the following models predicts the population, y, of Pennsylvania (in millions) in terms of x, the number of years since 2010. y = 0.24x + 12.7 y = -12.7x + 0.24 y = -0.24x + 12.7 y = 12.7x + 0.24

Walgreens sells both kleenex and nyquil. in a random sample of 5000 purchases, it was found that 1200 contained kleenex and 540 contained nyquil. these are not independent because sick people are more likely to buy both and healthy people more likely to buy neither. in looking into that, it was found that 360 purchases contained both. a. make a two-way table to display this information. fill in the table with the missing entries, and be sure your table has row and column totals. b. if we randomly select a purchase that contained kleenex, what is the probability it also contained nyquil? c. what percent of all purchases didn’t contain either product?
