Question

Marjorie is conducting a science experiment to measure the amount of pollution produced by cars that used gasoline containing different amounts of lead. Identify the dependent and independent variables.(1 point) Responses i= conducting a science experiment d= the amount of pollution i equals conducting a science experiment d equals the amount of pollution i= gasoline containing different amounts of lead d= type of car i equals gasoline containing different amounts of lead d equals type of car i= gasoline containing different amounts of lead d= the amount of pollution i equals gasoline containing different amounts of lead d equals the amount of pollution i= the amount of pollution d= gasoline containing different amounts of lead

Answer 1

In the context of Marjorie's science experiment, the independent variable is the gasoline containing different amounts of lead, as this is what she is manipulating to see its effect. The dependent variable is the amount of pollution produced by the cars, as this is what she is measuring in response to the changes in the independent variable.

So the correct identification would be:

• Independent Variable (i): gasoline containing different amounts of lead
• Dependent Variable (d): the amount of pollution
