given ƒ(x) = x+1 and g(x) = x^2, what is (g o f) (x)? (g o f) (x) = x^2 + x + 1
(g o f) (x) = x^2 (x+1)
(g o f) (x) = x^2 + 1
(gof) (x) = (x + 1)^2

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.
