Day 79 - 8.PFA.3 Flashcard: Independent & Dependent Variables

Front

What is a dependent variable?

Back

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

Front

What is an independent variable?

Back

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

Front

In the formula 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

If w represents the weight of mushrooms and v represents their value, which is the dependent variable?

Back

v is the dependent variable because its value depends on the weight of the mushrooms (w).

Front

In the context of a wind farm, what does m represent?

Back

m represents the average wind speed, which is the independent variable affecting the power produced.

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

Solve for y: 5y + 34 = -2(-7y + 1)

Back

y = 4.

Front

What is the formula for finding the total cost in Mary's cleaning service scenario?

Back

C = 7.5x + 25.

Front

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

Back

y also increases, showing a direct relationship.
