The group of points {(0, 1), (0,5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2,7). (3, 1), (5,7)} is a function. What do you notice about the two groups of
points? What do you think it means to be a function?

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
