In an experiment to see if light affected the amount of interaction, one group of students was put in a lighted room for an hour, and another group was put in a room that was totally dark. cameras recorded the n in each group. the independent variable in this experiment was?

The amount of light is an independent variable.

Step-by-step explanation:

Consider the provided information.

The independent variable is the variable that the experimenter changes or controls to test the dependent variable impacts.

A dependent variable is the variable that depends on the independent variable and that the experimenter is testing and measuring.

For example:

In a study to determine whether how long you practice affects your game, the independent variable is the time you spent on practice while the dependent variable is the affects on your game.

Now consider the provided information.

In an experiment to see if light affected the amount of interaction, one group of students was put in a lighted room for an hour, and another group was put in a room that was totally dark. Cameras recorded the n in each group.

Here, the light is controlled by the experimenter but affect of interaction is dependents on light.

Thus, the amount of light is an independent variable.

savings account is an account only used for saving money. this acts as an emergency source of funding for an individual. answer a would result in the money in his account to grow as it specifically states that interest is compounded daily at the rate of 2%

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
