After collecting all of the data, you determine that the finishing times are normally distributed with a mean of 2.8 hours and a standard deviation of .4 hour. a. what is the probability that a randomly chosen athlete completed the walk between 2 and 3.2 hours?
b. what is the probability that two randomly chosen athletes completed the walk in 3.6 hours or more?
c. what is the probability that four randomly chosen athletes completed the walk between 2 and 2.8 hours?

answer:     true

step-by-step explanation:

24+x=y

step-by-step explanation:

triangle and cube

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
