Answer 1

Answer:

Step-by-step explanation:

All prime numbers between 20 and 40 are as follows

23,29,31 and 37

Hence, the mean can be calculated as below

Mean = Sum of numbers / Number of numbers

(23+29+31+37)/4

We get,

=120/4

=30

Therefore, mean=30

Hi there! ☃️

First let's list all the prime numbers between 2 and 40 :

3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37

Therefore total number of prime numbers are 11.

=> $\:\boxed{\frac{3\: +\: 5\: +\: 7\: +\: 11\: +\: 13\: +\: 17\: +\: 19\: +\: 23\: +\: 29\: +\: 31\: +\: 37}{11}}$

=> $\:\sf{{195}{11}}$

=> $\:\sf{17.72}$
