From other source on the internet this question is:

Which absolute value expression represents the distance between 3 and - 2 on a number line?

Both are equivalent.

Explanation:

The distance between two numbers in a number line is the absolute value of the difference between the two numbers.

Thus, the distance between a number x and a number y is |x - y|, which is also equivalent to |y - x|.

In this case the distance between 3 and - 2 can be represented by either of the expressions:

Note that when you simplify them you get the same value:

B: 8%

Step-by-step explanation:

It asks for percentage of total students, so we add the male and female student totals for a total of 150 students. We also add the numbers of those that are left handed for a total of 12. We divide 12 by 150 (12/150) to get the decimal, 0.08, which is 8%.
