To find the mean, add up at the numbers and divide by the number of numbers in the set (6)
9 + 4 + 7 + 3 + 10 + 9 =
9 + 11 + 12 + 10
20 + 22
42
42 / 6 = 7
the mean is 7.
6 x 9 = 54
He has a total of 54 pages to grade.
54 - 12 = 42 pages
He still has to grade 42 pages.
Hope I helped!!
Uhh uhh this might not be right so don’t listen but I think the answer is 46 or sum I’m sorry
The mean of the data is 8
0.3x = 48
So x is 48/0.3
Therefore, 0.5 times 48/0.3 is the answer
