E: A randomly selected person accidentally killing a spider. F: A different randomly selected person accidentally swallowing a spider. A. E cannot affect F and vice versa because the people were randomly selected, so the events are independent. B. E cannot affect F because "person 1 accidentally killing a spider" could never occur, so the events are neither dependent nor independent. C. E can affect the probability of F because the people were randomly selected, so the events are dependent. D. E can affect the probability of F, even if the two people are randomly selected, so the events are dependent.

Automobile repair costs continue to rise with the average cost now at $367 per repair (U.S. News & World Report website, January 5, 2015). Assume that the cost for an automobile repair is normally distributed with a standard deviation of $88. Answer the following questions about the cost of automobile repairs. What is the probability that the cost will be more than $450? What is the probability that the cost will be less than $250? What is the probability that the cost will be between $250 and $450? If the cost for your car repair is in the lower 5% of automobile repair charges, what is your cost?

The distance a train travels between 2 cities is 540 miles. The train travels at a speed of 80 miles per hour. Matt set up these rates to find the time it took the train to travel between the 2 cities. 80 miles 1 hour = ? hours 540 miles What was Matt’s error? The first rate should be written as 80 hours to 1 mile. The second rate should be written as a rate of distance to time. The first rate should compare miles to miles. Matt did not make an error.
