Which of the following is the most appropriate unit to describe the rate at which people are entering a theme park

a. hours per person because the dependent quadquantity is the hours

b. hours per person because the dependent quantity is the people

c. people per hour because the dependent quantity is the hours

d. people per hour because the dependent quantity is the people

D. people per hour because the dependent quantity is the people

Step-by-step explanation:

The variable that we can be change is called the Independent variable.

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

Here people is the dependent variable and hours is independent variable as time passes the number of visitors of the park will be change.

And, Number of people can be calculate according to the hours. So, the word use here should be "hours per person".

Thus, Option (D) is the correct option only.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
