Question

The mean of 16 number is 8.if 2 is added to every number,find the new mean

Answer 1

Answer:

The new mean will be 10.

mean of 16 number = 8

Answer 2

Step-by-step explanation:

n= 16

assume sum of all 16 num is S

mean = S/16

S/16 = 8

If 2 is added to every num then 16 *2 = 32

then

new mean = (S + 32)/16

new mean = (S/16) + (32/16) = 8 + 2 = 10

new mean = 10.
