The equation of a parabola in its vertex form is y=a(x-h)²+k, <span>where (h, k) is the </span>vertex<span> of the </span>parabola<span>.
in this case, h=3, k=-2, so y=a(x-3)-2
plug (4,3) in the equation: 3=a(4-3)</span>²-2, a=5
so the coefficient of the squared expression is 5.

Answer:
166. 5
Step-by-step explanation:
Given the following :
Mean weight (m) = 142 lbs
Standard deviation (sd) = 14 lbs
Renne = 96 percentile, what is Renne's weight
Using the equation :
Zscore = (score - mean) / standard deviation
96 percentile = 0.96 is equivalent to a Zscore of
1.75
Hence,
1.75 = (score - 142) / 14
14 * 1.75 = score - 142
24.5 = score - 142
24.5 + 142 = score
Score = 166.5
