Question

if the mean of 7,4,x and 10 is 8, the value of x is​

Answer 1

Answer:

x = 11

Step-by-step explanation:

We know mean is the average of all these numbers in this given set. We also know to find what the sum of all numbers of the set is, we multiply the mean by the number of numbers. We get

8 × 4 = 32

So, we get this equation:

7 + 4 + 10 + x = 32

We simplify getting

21 + x = 32

We subtract both sides by 21 to get our answer:

x = 11
