For each situation below, state the independent variable and the dependent variable. a. A study is done to determine if elderly drivers are involved in more motor vehicle fatalities than all other drivers. The number of fatalities per 100,000 drivers is compared to the age of drivers. b. A study is done to determine if the weekly grocery bill changes based on the number of family members. c. Insurance companies base life insurance premiums partially on the age of the applicant. d. Utility bills vary according to power consumption. e. A study is done to determine if a higher education reduces the crime rate in a population

a. Dependent variable - fatalities

   Independent variable - age of the driver

b.  Dependent variable - grocery bills

   Independent variable - number of family members

c.  Dependent variable - insurance

   Independent variable - age of applicant

d.  Dependent variable - utility bill

   Independent variable - power consumption

e.  Dependent variable - crime rate

   Independent variable - higher education

Step-by-step explanation:

The independent variable is the variable that is used to predict the other variable, while the dependent variable is the variable that is been predicted.

The simple regression model comprises of one dependent variable (y)(y) and one independent variable (x)(x). It is used to predict the value of a dependent variable based on one independent variable.

Therefore,

a. The dependent variable is fatality and the independent variable is the age of the driver.

b. The dependent variable is grocery bills and the independent variable is the number of family members.

c. The dependent variable is insurance premium and the independent variable is the age of the applicant.

d. The dependent variable is the utility bill and the independent variable is power consumption.

e. The dependent variable is the crime rate and the independent variable is higher education.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
