Hey there! :D
Remember that the question said estimate.
So
47% rounds to 50%
.5 and 1/2 are equal to 50%
89 rounds to 90.
You could say that:
1/2*90
0.5*90
90/2
These will all work and will give you the same answer.
I hope this helps!

Answer: The vertex is located at (2, 2)</h3>
====================================================
Explanation:
The general vertex form is
y = a(x-h)^2 + k
When we compare the function your teacher gave you to this template, then we see that
The vertex is therefore (h,k) = (2,2)
The value of 'a' has no role in the vertex's location. This value determines how vertically stretched or compressed the parabola will be. Also, it determines if the parabola opens upward or downward (a > 0 for upward; a < 0 for downward).
The mean is 23 because it is the middle number
