A diver earned scores of 6.5 6.5 7.5 and 8.5 on his first four competition dives this season, which inequality represents all possible scores X, the diver can earn on his fifth dive in order to have a mean that is greater than 7.5 for the season
(6.5 + 6.5 + 7.5 + 8.5 + X)/5 > 7.5
(29 + X) > 37.5
X > 8.5
Therefore, the inequality representing all possible scores X the diver can earn on his fifth dive in order to have a mean greater than 7.5 for the season is X > 8.5.
