Question

the mean of 16 numbers is 8 if 2 is added to every number what will be the new mean​

Answer 1

Answer:

16

Step-by-step explanation:

16/2=8 if 8×2 as 2 added to every no. therefore new mean is 16

Answer 2

Answer:

Given,  there are 16 numbers

Mean = 8.Let their sum be x.

So mean = x/16 =8.

If two is added to each number then the  sum increases by 16*2 = 32.So, for finding the new mean we'll divide it  by 16

∴ Mean = (x+32)/16 ⇒ 8+2 =10.

So, the required new mean is 10.
