Answer: 89.7
Step-by-step explanation:
The mean of a data set is the average of all the information given. Therefore, the total combined score is the number of students multiplied by the mean
The total score of the first 44 students: 96.6*44 = <em>4250.4</em>
The total score of the later 13 students: 66.3*13 = <em>861.9</em>
(4250.4 + 861.9)/(44 + 13) = 89.7

=440
Step-by-step explanation:
the number is 440

they're on a ratio of 3:2, so if the small is 2, the large one is 3, and if the small one is 120, the large one is 180.
on a 3:2 ratio, 3 is larger than 2 by 1 unit, 1 is 50% of 2, or half, so the longer side is 50% larger.
