The answers to the question are are the equations
y = 0.08x²-1.6x+13
y = 0.08(x-10)²+5
<h3>How to solve for the system of equations</h3>
David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).
Vertex form of quadratic function is
y =
13 = a(x-10)²+5
let x = 20
a(20-10)²+5
13 = 100a + 5
take like terms
13 - 5 = 100a
8 = 100a
divide through by 100
a = 0.08
hence the equation would be
y = 0.08(x-10)²+5

When I use geogebra to draw the box plot, I get what you see in the attached image.
It's hard to say for sure since there are no numbers assigned to any of the boxplots, but it looks like
the answer is choice D. This is due to these things I've noticed
A) The median is closer to Q3 than it is to Q1
B) Q1 is very close to the min compared to the distance from Q3 to the max
The answer is 4
