3. What is the average (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive?
viktelen [127]
Hello!

The average mean (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive would be C. 100.

Explanation:

10 and 190 inclusive would mean that there are 19 terms.

To find the arithmetic mean, we must add all the numbers and divide by the amount of numbers.

If you add up all the terms, you will get 1,900. Now, divide that by the number of terms.

1,900 ÷ 19 = 100

Therefore, your answer is C. 100.

Have a wonderful day!
