Two angles are supplementary if the sum is 180 the larger angle measures 8° more than three times the measure of a smaller angle if X represents the measure of the smaller angle and needs to angles are supplementary find the measure of each angle

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.
