Question

The mean of 15 numbers is 27. If each number is divided by 8,
the new mean?​

Answer 1

Answer:

3.375

Step-by-step explanation:

Let the sum of all the 15 numbers be x

Then, from the mean formula

27 = x / 15

x = 27 × 15

x = 405

Now, if each number is divided by 8 then their new sum is x/8

New mean = (x/8) / 15

= x/(8 × 15)

= 405 / (8 × 15)

= 3.375
