Answer:
<h2><u><em>
36 - x</em></u></h2>
Step-by-step explanation:
A woman buys 3 dezen eggs. Later she discovers that x of them are broken. How many mang eggs are not broken
3 = 3
Dozen = 12
x = broken eggs
3 * 12 - x =
36 - x
-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.

Answer:
n=-19
Step-by-step explanation:
-37+n=-56
-37+37+n=-56+37
n=-19
In order to find the standard deviation you must find the mean, then subtract the mean to the square, then find the mean of the square, then take the square root of that and you have you're answer.
Hope this helps!
Good luck.
