Question

the length average (arithmetic mean) of 5,6,7 and w is 8. what is the value of w?​

Answer 1

Arithmetic means = Sum of all observations/total number of observations

Arithmetic Mean, 8 = (5+ 6 + 7 + w)/4

8*4 = (5+ 6 + 7 + w)

5+ 6 + 7 + w = 32

18 + w = 32

w = 32 - 18 = 14 ——> Answer

Answer 2

The value of w is 14

Step-by-step explanation:

$Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}$

We are given that the length average (arithmetic mean) of 5,6,7 and w is 8.

So,$8 = \frac{5+6+7+w}{4}$

32 = 18+w

32-18=w

14=w

Hence The value of w is 14
