Front

What is an independent variable?

Back

An independent variable is the 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 the variable that is measured and affected in an experiment, depending on the independent variable.

In the equation C = 7.5x + 25, what does C represent?

Back

C represents the total cost of cleaning the house.

Front

In the equation y = 2x, what does x represent?

Back

x is the independent variable that affects the value of y.

Front

In the context of a game show, if c is the number of correct answers, what is m?

Back

m is the amount of prize money won based on the number of correct answers.

Front

If the weight of mushrooms (w) affects their value (v), which is the independent variable?

Back

w (the weight of the mushrooms) is 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 a wind farm, if the average wind speed (m) affects the amount of power produced (p), which variable is dependent?

Back

p (the amount of power produced) is the dependent variable.

Front

What does it mean if a variable is dependent?

Back

It means that the variable's value is determined by the changes in another variable.

Front

In the formula y = 2x, if x increases, what happens to y?

Back

y increases because it is directly proportional to x.
