@tootsi123 What is an independent variable?

alivejeremy · Answer

So you looking for independent variable?

tootsi123 · Answer

Yes @alivejeremy

tootsi123 · Answer

Independent variable is one that can be controlled or changed.

So this is English?

alivejeremy · Answer

or math

tootsi123 · Answer

It is math, specifically Algebra 2

normanc · Answer

You are correct because the other two variables (his high school and his age) depend on each other.  His diet does not depend on another variable in that example, so it would be the independent variable.

alivejeremy · Answer
