Step-by-step explanation:
Using the section formula , if a point ( x , y ) divides the line joining the points ( x1 , y1 ) and ( x2 , y2 ) into the ratio m : n , then
( x , y ) = ( mx2 + nx1 / m + n , my2 + ny1 / m + n)
Let the points be A(-8,−2) and B(6,19). Let a point P(x,y) divides AB in the ratio 5:2
Therefore, we have
![P(x,y) =( \frac{5 \times 6 + 2 \times - 8}{5 + 2} , \: \frac{5 \times 19 + 2 \times - 2}{5 + 2})](https://tex.z-dn.net/?f=P%28x%2Cy%29%20%3D%28%20%20%5Cfrac%7B5%20%5Ctimes%206%20%2B%202%20%5Ctimes%20%20-%208%7D%7B5%20%2B%202%7D%20%2C%20%5C%3A%20%20%5Cfrac%7B5%20%5Ctimes%2019%20%2B%202%20%5Ctimes%20%20-%202%7D%7B5%20%2B%202%7D%29%20)
![P(x,y) = ( \frac{30 + ( - 16)}{7} , \: \frac{95 + ( - 4)}{7} )](https://tex.z-dn.net/?f=P%28x%2Cy%29%20%3D%20%28%20%5Cfrac%7B30%20%2B%20%28%20-%2016%29%7D%7B7%7D%20%2C%20%5C%3A%20%20%5Cfrac%7B95%20%2B%20%28%20-%204%29%7D%7B7%7D%20%29)
![P(x,y) = (2, 13)](https://tex.z-dn.net/?f=%20P%28x%2Cy%29%20%20%3D%20%282%2C%2013%29)
Answer:
0.36 = 36/100 = 9/25
so the simplest form is 9/25
Using sampling concepts, it is found that the sample would not support a valid inference, as both alphabetized and non-alphabetized students should be sampled.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
The school has both alphabetized and non-alphabetized students, and both groups should be sampled for a valid inference to be made. Since only alphabetized students are sampled, the sample would not support a valid inference.

Answer:
X-intercept: (1.5,0)
y-intercept: (0,-2)
the 1.5 can also be written as 3 over 2 in fraction form.
Hope this helps! :)
The correct answer would be C
