Define independent variable, dependent variable, and control variable. give an example of each in a hypothetical experiment

Independent and dependent variables are commonly used variables whereas controlled variables are less used.

The variable that we can change is called Independent variable.

The dependent variable depend upon the independent variable, as we change the value of independent variable the value of dependent variable is also get changed.

And the constant term in our experiment is called the Control Variable. For example Temperature is taken constant during experiment.

Suppose we are interest to know that "Does a bean plant is grown best in shade or sun?"

Here the amount of light that plant received can be changed, so it is independent variable.

The plant's growth is dependent variable.

And, amount of water used, kind of soil is kept constant in both experiment plant grow in shade and plant grow in sun, so both variable is Control Variable.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
