Answer:
A multiple regression equation for this model can be expressed as:
Step-by-step explanation:
To model this problem as a multiple regression equation, we need to define which are the independent and dependent variables.
The dependent variable is the one which we want to predict for any set of independent variables values. This is the case of the driver's automotive insurance monthly premiums.
The driver's automotive insurance monthly premiums is the dependent variable "y".
The independent variables are the ones that explain the dependent variable variation. In this case there are: number of miles driven per week (x1); the age of the car, in years (x2); and the number of accidents in which the driver has been involved in the past 5 years (x3).
Then, a multiple regression equation for this model can be expressed as:
We need to find out how much 17 percent of 2,500 is, and then subtract that amount by 2,500. We can use proportions to use this. We can set up a fraction with x/2500 and another fraction with 17/100. Then, we need to cross multiply. This gives us 42,500. Next, we can divide by 100. This gives us 425. We know that they will save $425 if they decrease their energy use by 17%. We now need to subtract $425 from $2,500. This gives us $2,075. If the company is successful in decreasing their energy use by 17%, their bill would be $2,075.

Answer:
1020 in a day
Step-by-step explanation:
8 men will earn 8/3 what 3 men earn, so will earn ...
(8/3)(180 /day) = 480 /day
12 women will earn 3 times what 4 women earn, so will earn ...
3(180 /day) = 540/day
The total earned by 8 men and 12 women is ...
(480 +540) /day = 1020/day
8 men and 12 women will earn 1020 in a day.
