Its B. 2/13, becouse you do the math correctly and you will find it eventually
Answer:
$7
Step-by-step explanation:
If you use "Is over of" the equation will be ?/100*7/100, therefore after simplifying your answer is $7
Brainliest would be appreciated! :-)
The Standard deviation could only be zero if all the data points in your set are equal. If all data points are equal, there is no deviation.
Starting with ...

1) Multiply by the inverse of the coefficient multiplying the sum with M, then subtract m.

2) Multiply by g/T²

Notice that our function

is a parabola, and the vertex form of a parabola is:

where (h,k) are the coordinates of its vertex.
The first thing we need to do is find the vertex (h,k) and to do that we are going to use the vertex formula:

, and then we are going to evaluate our function at

to find

.
We know for our problem that

, and

, so lets replace those values in our vertex formula to find

:




Now, we are going to evaluate our function at -6 to find

:



Now that we have our vertex, where

and

; lets replace those values in our vertex form equation:
![f(x)=-5[x-(-6)]^{2} +(-1)](https://tex.z-dn.net/?f=f%28x%29%3D-5%5Bx-%28-6%29%5D%5E%7B2%7D%20%2B%28-1%29)

We can conclude that the vertex form of our function is

, and its vertex is (-6,-1).
