Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9
vertex is at (5,-9)
the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever
verrtex is at (5,-9)
The frequency distribution chart of the math quiz has a data that is skewed left.
<h3>How to interpret the shape of the histogram?</h3>
From the complete question (see attachment for histogram), we have the following highlight:
The dataset on the right-hand side is taller than those on the left.
This means that the dataset is skewed left.
Hence, the statement that best describes the data is (a) The data is skewed left.

Answer:
A. 115°
Step-by-step explanation:
180° - 65° = 115°
$20.25 because 8.50 and 8.50 equal 17 and then subtract 2.00 makes 15, and then add 5.25 and you end up with 20.25
