32,34,35,36,38,39,40,42,44,45,46,48&49

Answer 2

Step-by-step explanation:

first , we will write all the prime nos. between 30 and 50.

prime nos. between 30 and 50 are 31,

37, 41, 43 and 47.

We know that,

Average=

Sum of observations / No of observations.

Sum of obsevations = 31, 37,41, 43, 47= 199.

Total no of observations = 5

Average (A )= sum of obsetvations / No of observations.

(A) = 199/5

(A) = 39.8

Hence, average = 39.8
