Question

Find the mean of the first 7 odd prime number?​

Answer 1

Answer: 75/7 or 10.71 (rounded)

Explanation:

Mean = Average

To find the average you should add all the numbers together and then divide it by the amount of numbers.

In this question, the formula is
`(n_1+n_2+n_3+n_4+n_5+n_6+n_7)/(7)`

----------------------------------------------------------------------------------------

The list of the first 7 odd prime numbers:

3, 5, 7, 11, 13, 17, 19

Now, add them together

3+5+7+11+13+17+19=75

Divide the sum by 7

75÷7=75/7=10.71 (rounded)

Hope this helps!! :)
