Question

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

Answer 1

(6+6+4+p+10)/5=8
26+p=40
p=14

Answer 2

$mean = \frac{sum \: of \: observations}{number \: of \: observatons}$


Here,


$8 = \frac{6 + 4 + 7 + p + 10}{5} \\ \\ 8 \times 5 = 27 + p \\ \\ 40 = 27 + p \\ \\ 40 - 27 = p \\ \\ 13 = p$



I hope this will help you
