BaLLatris [955]

Answer:

112.5 ft

Step-by-step explanation:

The maximum is achieved at vertex of parabola.

The x- coordinate of the vertex is determined by x = - b/(2a).

x = - 15/(-0.5*2) = 15

The maximum height is the corresponding y- coordinate

y = - 0.5(15²) + 15(15) = 112.5 ft

vova2212 [387]

Answer:

The margin of error for the 99% confidence level for this sample is ±2.23.

None of the given figures is close to the answer:

E. None of the above

Step-by-step explanation:

margin of error (ME) around the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic of the 99% confidence level (2.576)

s is the population IQ standard deviation (15)

N is the sample size (300)

Using these numbers we get:

ME= $\frac{2.576*15}{\sqrt{300} }$ ≈ 2.23
