Harley Boyle · Answer 1

Reaction time

Explanation:

Dependent variables are the actual variables being measured during the course of an experiment whose values depends on the independent variables. In other words, dependent variables are those whose values varies as a result of change in the values of independent variables during an experiment.

In this case, the independent variable is the amount of alcohol intake while the dependent variable is the reaction time. As the amount of alcohol taken varies, the reaction time will also vary as the case may be.

Giovani Rangel · Answer 2

Answer: b. Braking speed.

Explanation:

The options are:

a. amount of alcohol

b ... braking speed

c. red light

d. degree of intoxicatio

The correct option is option B, braking speed.

Considering the dependent variable, this is the braking speed, which is measured for all participants.
