Question

The average of 8 numbers is 16. If each of the numbers is multiplied by 5, what is the new average?​

Answer 1

Answer:

128

Step-by-step explanation:

Let eight numbers be x1 ,x2 ,x3, …….. x8.

To take average we add all numbers an divide by the total numbers we have

So avg is

(x1 + x2+x3+………..x8)÷8= 16

Now all numbers are multiplied by eight

So eight we will be taking as common

Therefore average is

8 (x1+ x2+ x3………..x8)÷8

Now we know (x1+ x2+ x3………x8)÷8= 16

So it becomes

8×16

Which is equal to 128.
