63
The mean (average) of 76, 63, 79, 63, and 74 is 71.
-16 - 63 = -79
63/79 it can't be simplified any further
63
It is: 9 times 7 = 63
30
The factors of 13 are: 1, 13 The factors of 21 are: 1, 3, 7, 21 The factors of 63 are: 1, 3, 7, 9, 21, 63 because these are the positive integers that divide evenly into 63 with no remainder. The factors of 79 are: 1, 79
7*9 = 9*(10 - 3) = 90 - 27 = 63
The product is the answer. 7 x 9 = 63 63 is the product.
9 x 7 =63 pretty simple there
Average = (50%+89%+79%+63%+63%+61%+21%) ÷ 7 = 426 ÷ 7 = 60.86%
