PLEASE HELP!!!

<h3>Answer: B)  2.9  approximately</h3>

==================================================

Explanation:

The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the (x-\overline{x})^2 terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so \sum(x-\overline{x})^2 = 34

From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list

So,

s = \sqrt{\frac{1}{n-1}\sum(x-\overline{x})^2} \\\\s = \sqrt{\frac{1}{5-1}*34} \\\\s = \sqrt{\frac{1}{4}*34} \\\\s = \sqrt{0.25*34} \\\\s = \sqrt{8.5} \\\\s \approx 2.91547594742266 \\\\s \approx 2.9 \\\\

This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.

A sound receiving dish used at outdoor sporting events is constructed in the shape of a paraboloid, with its focus 8 inches from
bixtya [17]

Answer:

w≅8.46ft

Step-by-step explanation:

Data

focus=8

vertex=(0,0)

width=?

depth (y)=3ft

parabola equation: (x-h)^{2}=4p(y-k); then for V=(0,0), x^{2} =4py, be focus(f)=8in;  x^{2} =4*8*y=32y → y=\frac{x^{2} }{32}

we have that y=3ft then 3=\frac{x^{2} }{32}; but 1in≅0.083ft so x^{2} =3*32*0.083=7.968 → x=±2.82, finally w=3*2.82≅8.46ft
