Mean: 52.2 because its the average of all the numbers
Range: 2 because (60-58)
Median: 53 because its in the middle of all the numbers
Mode : None
Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the 
values in the table. In other words, we need to replace with each value in our given function and simplify.
- For x = 0
Since 
and 
, our first point is (0, -1)
- For x = 1
Our second point is (1, -4)
- For x = 2
Our third point is (2, -5)
- For x = 3
Our fourth point is (3, -4)
- For x = 4
Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
So first let’s find the area of the rectangle. The formula for finding the area of a rectangle is A=l x w.
The length is 10ft and the width is 8ft.
A=10ft x 8ft=80ft^2
The area of the rectangle is 80ft^2.
Now let’s find the area of the triangle. The formula for finding the area of a triangle is A=h x b/2. Both the height and the base of the triangle is 4ft.
A=4ft x 4ft/2=8ft^2.
The area of the triangle is 8ft^2.
Now to find the area of the entire shape. Add the area of the rectangle and the area of the triangle.
80ft^2+8ft^2=88ft^2
The total area of the shape is 88ft^2.
