Question

Is mean of the following distribution is 8 find the value of p 5, 10, p+ 3, 7, 8

Answer 1

Answer:

$\because mean = \frac{5 + 10 + p + 3 + 7 + 8}{5} \\ \\ \therefore \: 8 = \frac{33 + p}{5} \\ \\ \therefore \: 33 + p = 5 \times 8 \\ \\ \therefore \: 33 + p = 40 \\ \\ \therefore \: p = 40 - 33 \\ \\ \huge \orange{ \boxed{\therefore \: p = 7}}$
