To receive an A grade, a student must average 100 or less but more than 93. If Emma received an A in the course and had five grades of 92, 87, 97, 83, and 100 before taking the final exam, what were the possible grades for her final if there were 100 points possible? (Assume all six grades are weighted equally and let x represent the
unknown score.)

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.
