For the equation F(x) = ax² + bx + c we have:

maximum value if a<0
minimum value if a>0

F(x) = -3x² + 18x + 3 ⇒ a = -3, b = 18

a < 0 ⇒ the function has a maximum value

Quadratic function has the maximum value (or minimum) at vertex of its parabola.

The maximum value is k at x=h where: $h=\dfrac{-b}{2a}$ and k = F(h)

$h=\dfrac{-18}{2\cdot(-3)}=3\\\\F(3)=-3\cdot3^2+18\cdot3+3=-27+54+3=30$

Therefore:

<h3> The function has a maximum value of 30 at x = 3</h3>

Considering the middle 95% of the data, determine the margin of error, to the nearest hundredth, for the simulated results. In t

The 95% margin of error simony states that there is a 95% probability that the confidence interval contains the true population mean.

<h3>What is a margin of error?</h3>

It should be noted that the margin of error simply means a measurement that accounts for the difference between the actual result and the projected result in a survey sample.

In this case, the 95% margin of error simply states that there is a 95% probability that the confidence interval contains the true population mean. This is the radius of the 95% confidence interval.
