First, let's make a two-way table using a matrix:
![\left[\begin{array}{cccc}&Tennis&No&Total\\Male&7&5&12\\Female&9&6&15\\Total&16&11&27\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%26Tennis%26No%26Total%5C%5CMale%267%265%2612%5C%5CFemale%269%266%2615%5C%5CTotal%2616%2611%2627%5Cend%7Barray%7D%5Cright%5D%20)

Hello,
Answer C
center (0,0)
a²=58
b²=9
c²=a²-b²=49
f(x)=1/2x^2-2x+20
h = -b/2a is the axis of symmetry
h = - (-2)/ (2 * 1/2)
h = 2 /1
the axis of symmetry is x=2
D.
The flight of the bird is symmetric about the line x = 2 feet, which indicates that the bird is at the same height when it is horizontally 1 foot and 3 feet away from where it began its flight.
$29.96 because 7% of 28 is 9.96 and 28+29.96 if you want to check my answer get a calculator and do 28x107%
Since we are adding two positive numbers here, their sum could be found by writing either
8
+4
---
12
or
4
+8
---
12
