Question

Find the mean of the first 10 whole numbers.

• A. True
• B. False
• C. 5
• D. 5.5

Answer 1

The correct option is A

True

First 10 whole numbers are 0, 1, 2, 3 ....10.
Their mean is the ratio of sum of all the numbers and the number of numbers.
Which is,
$\frac{0+1+2+3+4+5+6+7+8+9}{10}=4.5$
