M7HN/Prealgebra- Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is a variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is a variable that is measured and affected in an experiment. It depends on the independent variable.

Front

In the equation m = 75d, which variable is dependent?

Back

m (the amount of money Sarah will raise) is the dependent variable.

Front

In the equation m = 12h, which variable is independent?

Back

h (the number of hours Ty works) is the independent variable.

Front

What does the term 'variable' mean in mathematics?

Back

A variable is a symbol used to represent a number that can change or vary.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable directly affects the dependent variable, as the dependent variable's value is determined by the independent variable.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

In an experiment, if the height from which a ball is dropped is increased, what happens to the height it bounces?

Back

The height that the ball bounces (dependent variable) is likely to increase as the height from which it is dropped (independent variable) increases.

Front

What is the formula for the volume of a sphere?

Back

V = 4πr³, where V is the volume and r is the radius.

Front

In the context of the volume of a sphere, which variable is dependent?

Back

V (the volume of the sphere) is the dependent variable.
