Question

the mean of 16 number is 8 if 2 is added to every number find the new mean​

Answer 1

Answer:

Step-by-step explanation:

There are 16 numbers, and their mean is 8.

Let their sum be S. So mean = S/16 =8.

If two is added to each number , the sum increases by 16 x 2 = 32.

To find the mean we divide by 16, so mean = (S+32)/16 =8+2 =10

Hence the new mean is 10

Answer 2

Answer:

There are 16 numbers, and their mean is 8. ... So mean = S/16 =8. If two is added to each number , the sum increases by 16 x 2 =32.
