Question

2. The mean of 8 numbers is 136.5. The sum of these numbers is (a) 1029 (b) 1209 (c) 1092 (d) 1902.

Answer 1

Answer:

n=8

Let the sum be x

Now

mean = sum/n

136.5 = x/8

or, 136.5 × 8 = x

so, x = 1092

So, (c)1092 is the correct answer.

Answer 2

1092 so it’s c the mean is adding all the numbers and dividing it by the amount of numbers so for example 1 2 3 the mean would be 1+2+3/3 since there are 3 numbers hope this helps
