Answer:
Population parameter
Step-by-step explanation:
Since the average price of a whole town at a new dealership is described. A random sample from a town was not isolated for study. In fact the entire statistics of the town was considered in the mean price of a car. Hence, the average price given in our case will be a population parameter.

Answer:
437mm²
Step-by-step explanation:
First we need to find the total area of the rectangle. The area of a rectangle can be found by using the formula:
A = L x W
L = 15mm
W = 38mm
So now we plug it into our formula.
A = 15mm x 38mm
A = 570mm²
Now that we have the total area, we now need to solve for the area of the triangle.
The area of a triangle can be found by using the formula:
![A=\dfrac{1}{2}bh](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7Dbh)
To find the height of the triangle we take the total height and subtract it to the measurement given in the figure.
h = 15mm - 8mm
h = 7mm
b = 38mm
Now that we have both the base and height we can use the formula for the triangle.
![A=\dfrac{1}{2}38*7](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D38%2A7)
![A=\dfrac{1}{2}266](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D266)
![A=0.5*266](https://tex.z-dn.net/?f=A%3D0.5%2A266)
![A=133mm²](https://tex.z-dn.net/?f=A%3D133mm%C2%B2)
Now that we have the area of both the triangle and the rectangle, we simply subtract the area of the triangle to the area of the rectangle.
Shaded Area = 570mm² - 133mm²
Shaded Area = 437mm²
The area of the shaded area is equal to 437mm².
Passes through (3, 0) and is perpendicular to 2x - y = 5
Turn our given equation into y=mx+b form.
2x - y = 5
Subtract 2x from both sides.
-y = -2x + 5
Divide both sides by -1.
y = 2x - 5
So, our slope is 2.
However, because our equation is perpendicular, we must find the negative reciprocal of 2.
Slope₁ = 2
Slope₂ = -1/2
y - y₁ = m(x - x₁) (3, 0)
Plug everything in.
y - 0 = -1/2(x - 3)
y = -1/2x + 3
