a) quantitative and descriptive
b) quantitative and inferential
c) qualitative and descriptive
d) qualitative and inferential

The correct answer should be D) Qualitative and inferential

That is because he does not use quantity, but rather the quality of the migraines to create an opinion on the matter. The severity helps him infer what needs to be done.

144

Step-by-step explanation:

We are given that

106 balls+_=250 balls

We have to find the  unknown  number of balls in model.

Let x be the unknown number of balls.

To find the unknown number of balls we will use subtraction property of equality.

Substitute the value

This is the algebraic expression for this model

Using subtraction property of equality

Then, we get

After simplification, we get

Hence, the unknown number=144
