Question

If the mean of 6,4,7 p and 10 is 8 find the value of p

Answer 1

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

I hope you understood.

If you have any doubt, then you can ask me in the comments.

Answer 2

Answer:

6+4+7+10+p =

27+p/5 = 8

= 27+p =8×5 =(40)

= p=40-27

P =13
