The number of winners that Heather can expect is 300.
<h3>How many winners can be expected?</h3>
The first step is to determine the total number of winners to the total number of players using the information in the table.
- Total number of winners = 52 + 63 + 65 = 180
- Total number of players = 123 + 155 + 172 = 450
Ratio = 180 / 450 = 0.40
Number of winners if there are 750 players = 0.40 x 750 = 300 winners

Answer:
y=-3/16(x-8)^2+12
Step-by-step explanation:
Refer to the vertex form equation for a parabola:
y=a(x-h)^2+k where (h,k) is the vertex.
Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:
0=a(16-8)^2+12
0=64a+12
-12=64a
-12/64=a
-3/16=a
Therefore, your final equation is y=-3/16(x-8)^2+12
