lets say theres a problem that goes like this, brandy persuaded her teacher to let her retake the missed test that had a 0% and scored a 75 , her original scores were 80 92 91 75 89 84 0 and 85, what would be her new mean
80 92 91 75 89 84 75 and 85 so we have
(80 + 92 + 91 + 75 + 89 + 84 + 75 + 85) / 8 = [671 ] / [8 ] = about 83.9
