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:

This problem can be solved by the Thales’s theorem, which states:
<em>Two triangles are similar when they have equal angles and proportional sides </em>
It should be noted that to apply Thales' Theorem, it is necessary to establish <u>the two triangles are similar</u>, that is, that t<u>hey have the corresponding angles equal or that their sides are proportional to each other. </u>
<u />
Now, if we measure the shadow of the flagpole and the shadow of the person, <u>at the same moment</u>, we can use the first Thales' Theorem to calculate the height of the flagpole, knowing the height of the person.
In this case we have two similar triangles (Figure attached) where is the height of the flagpole,
is the height of the person,
is the length of the shadow of the flagpole and
is the length of the shadow of the person.
Having this clear, we can write the following relation with both similar triangles:
(1)
We know all these lengths except , which is the value we want to to find.
So, in order to approach this problem we have to find from equation (1):
Then:
>>>>>This is the height of the flagpole
