Question

Find the mean of the first five prime numbers .

Answer 1

First five prime numbers are 2, 3, 5, 7 and 11

So mean = (2 + 3 + 5 + 7 + 11 ) / 5
      mean  = 28/5
      mean = 5.6

Answer 2

Answer:

Mean of first 5 prime numbers = 5.6

Step-by-step explanation:

2,3,5,7,11are first five prime numbers.

/* We know that,

$\boxed {Mean(x)\\=\frac{Sum\: of \: the \: observations }{Number \: of \:observations }}$ *\

Now ,

$Mean = \frac{2+3+5+7+11}{5}\\=\frac{28}{5}\\=\frac{56}{10}\\=5.6$

Therefore,

Mean of first 5 prime numbers = 5.6
