Question

Can anyone help me please?!
Principle is the independent variable and interest is the dependent variable of this relation.

Principle 10 100 1,000 10,000
Interest 2 20 200 2,000
True
False

Answer 1

"Principle is the independent variable" means it dosnt depend on other values
"interest is the dependent variable " means it depends on other values ie the principle
so as the principle goes up does the interest follow in an explainable way

Answer 2

That sounds like "True."

Answer 3

I'm thinking this way:

When you know the principal amount, the rate and the time. The amount of interest can be calculated by using the formula: I = Prt

Answer 4

What is earned in interest depends upon the amount of the invested principal. Of course, there are other variables. In the example you posted, you are given the Principal and the Interest depends upon that (as well as interest rate and time).
