A horizontal translation 4 units to the left
73 degree
This is because BC and P is parallel lines so just use the parallel rules
Using it's formula, it is found that Val's margin of error is of 9.8 pounds.
<h3>Margin of error:</h3>
The margin of error is given by the following equation:
![M = 1.96\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=M%20%3D%201.96%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
In which:
- s is the standard deviation.
In this problem:
- The standard deviation is of 50, hence
.
- Val weighed 100 cows, hence
.
Then:
![M = 1.96\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=M%20%3D%201.96%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
![M = 1.96\frac{50}{\sqrt{100}}](https://tex.z-dn.net/?f=M%20%3D%201.96%5Cfrac%7B50%7D%7B%5Csqrt%7B100%7D%7D)
![M = 9.8](https://tex.z-dn.net/?f=M%20%3D%209.8)
Val's margin of error is of 9.8 pounds.

Answer: 57
Step-by-step explanation:
28 1/2 / 1/2
make 28 and 1/2 into 57/2
so now 57/2 divided by 1/2
the same as 57/2 times 2/1
multiply straight across
(57)(2)/(2)(1)
114/2
57
A tangent line is always perpendicular to the radius that shares the point of tangency. In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.
