Answer 2

Complete step by step answer:

Let us first define the mean. Mean is also called the Arithmetic Mean n the average of the numbers also called a central value of a set of numbers. To calculate mean,

1. Add up all the numbers

2. Then divide by how many numbers there are.

Example: Calculate the mean of the first 5 natural numbers. The first five natural numbers are 1, 2, 3, 4, 5.

Mean=Sum of first 5 natural numbers5

⇒Mean=1+2+3+4+55

⇒Mean=155

⇒Mean=3

Similarly, we will calculate the mean of 6, 4, 7, p and 10. Using the formula of mean, we have,

Mean=Sum of all termsNumber of the terms

⇒Mean=6+4+7+p+105

⇒Mean=27+p5

Given that the mean of 6, 4, 7, p and 10 is 8.

⇒Mean=8=27+p5

Considering the RHS of the above equation, we have,

⇒8=27+p5

Multiplying by 5 on both the sides, we get,

⇒40=27+p

⇒27+p=40

⇒p=40−27

⇒p=13

So, the value of p is 13.
