What is the solution set for StartAbsoluteValue StartFraction x Over 2 EndFraction EndAbsoluteValue = 8?
s = 4 and x = 16
x = negative 4 and s = 4
s = negative 8 and s = 8
x = negative 16 and x = 16

a) the variable is the number of fragments per 100 square meters

b) the variable is quantitative

Step-by-step explanation:

Data

a. The variable is an quantity that can be manipulated to achieve the desired result. For example, if we had the equation:

y = 2 x + 5

The variable will be x. Therefore, the output y depend on the input values of x.

In this question, the archaeologist wants to estimate the number of ferromagnetic artifacts .  He can only do that by determining the artifacts per 100 square meters.

b. The variable is quantitative. It requires physical counting.
