Answer:
The x coordinate is 2
Step-by-step explanation:
Given
![A = (-2,5)](https://tex.z-dn.net/?f=A%20%3D%20%28-2%2C5%29)
![C = (6,-1)](https://tex.z-dn.net/?f=C%20%3D%20%286%2C-1%29)
Required
Determine the x coordinate of B
Since B is the bisector of AC, then B is the midpoint and will be calculated using;
![B(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})](https://tex.z-dn.net/?f=B%28x%2Cy%29%20%3D%20%28%5Cfrac%7Bx_1%20%2B%20x_2%7D%7B2%7D%2C%5Cfrac%7By_1%20%2B%20y_2%7D%7B2%7D%29)
Considering the x coordinates alone;
![x = \frac{x_1 + x_2}{2}](https://tex.z-dn.net/?f=x%20%20%3D%20%5Cfrac%7Bx_1%20%2B%20x_2%7D%7B2%7D)
Where
and ![(x_2,y_2) = (6,-1)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%286%2C-1%29)
Substitute values for x1 and x2
![x = \frac{-2 + 6}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-2%20%2B%206%7D%7B2%7D)
![x = \frac{4}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4%7D%7B2%7D)
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
<em>Hence;</em>
<em>The x coordinate is 2</em>
<span>Mean -to-MAD ratio is the division of the Mean by the Mean Absolute Deviaion (MAD). For the set 1, mean / MAD is 10.3 / 1. 6 = 6.4375; and for the set 2, Mean / MAD is: 12.7 / 1.5 = 8.467. This is a measure of disperssion of a set of values. MAD is calculated as the sum of the absolute differences of the values and the mean.</span>
