Answer 2

Answer:

The mean of 6, 4, 7, p and 10 is 8, according to your question. So, let's write this statement as an equation. Then, solve the equation and find the value of p. See this whole procedure to understand.

Mean of 6, 4, 7, p and 10 = 8

=> 6 + 4 + 7 + p + 10

_____________ = 8

5

=> (6 + 4 + 7 + 10) + p

______________ = 8

5

=> 27 + p

_____ = 8

5

=> 27 + p = 8 × 5

=> 27 + p = 40

=> p = 40 - 27

=> p = 13

I have used this formula:

Sum of observations

Mean = __________________

Number of observations
