Answer:
is it 4.40?
Step-by-step explanation:
Answer:
16 to 4
Step-by-step explanation:
8 to 2 can be reduced to 4, so to have a ratio equivalent, it must be able to be reduced to 4 also. An example would include, 16 to 4.
Answer:800
Step-by-step explanation:
![Mean(\mu )=\$ 4300](https://tex.z-dn.net/?f=Mean%28%5Cmu%20%29%3D%5C%24%204300%20)
and ![P(X>6140)=0.0107](https://tex.z-dn.net/?f=P%28X%3E6140%29%3D0.0107)
![P(X>x_0)=0.0107](https://tex.z-dn.net/?f=P%28X%3Ex_0%29%3D0.0107)
![P\left ( \frac{X-\mu }{\sigma}](https://tex.z-dn.net/?f=P%5Cleft%20%28%20%5Cfrac%7BX-%5Cmu%20%7D%7B%5Csigma%7D%3C%5Cfrac%7Bx-%5Cmu%20%7D%7B%5Csigma%7D%20%5Cright%20%29%3D0.9893)
![P\left ( z](https://tex.z-dn.net/?f=P%5Cleft%20%28%20z%3C%5Cfrac%7Bx-%5Cmu%20%7D%7B%5Csigma%7D%20%5Cright%20%29%3D0.9893)
![\frac{x-\mu }{\sigma}=InvNormal(0.9893)](https://tex.z-dn.net/?f=%5Cfrac%7Bx-%5Cmu%20%7D%7B%5Csigma%7D%3DInvNormal%280.9893%29)
Using Z table to get InvNormal(0.9893)=2.30
![\frac{6140-4300}{\sigma}=2.30](https://tex.z-dn.net/?f=%5Cfrac%7B6140-4300%7D%7B%5Csigma%7D%3D2.30)
![\sigma =\frac{6140-4300}{2.30}=800](https://tex.z-dn.net/?f=%5Csigma%20%3D%5Cfrac%7B6140-4300%7D%7B2.30%7D%3D800)
Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)
