Answer:
b < 10
Step-by-step explanation:
-b - 2 > 8

-b > 10
Divide both sides by -1. When dividing by a negative, flip the inequality sign.
b < 10.

<h3>Explanatory and response variables:</h3>
- The variables of an experiment are divided into explanatory and response.
- The response variable is the one that is the focus of the study, that is, the one that can be changed.
- The explanatory is the one that explains the reason of the change in the response variable.
In this problem, the <u>age can effect the political party preference</u>, hence:
