Q.3
The
mean of first prime number​

Answer 1

Answer:

Solution: First five prime numbers are 2, 3, 5, 7 and 11. The mean or the average formula is = Sum/no. = (2 + 3 + 5 + 7 +11)/5 = 5.6.

Step-by-step explanation:

Answer 2

Prime numbers are those which are only divisible by ONE or by the number itself.

First 10 prime numbers are as follows:

1.2

2.3

3.5

4.7

5.11

6.13

7.17

8.19

9.23

10.29

Now we will add all the numbers: 2+3+5+7+11+13+17+19+23+29=  129

Now, we will divide the answer by 10, s they are total 10 prime numbers:

129/10= 12.9

12.9 is the mean of first 10 prime numbers.
