Answer:
5/9
Step-by-step explanation:
If you draw the triangle out on a grid papar and draw a line across the 2 marker point from XY up of the YZ side, you will see that the line from that marker point across to the hypotenuse is actually 8. Then you find the area of the little triangle with legs 8 and 4 (since 6-2 is 4), and the area is 16. After that, find the total area of the big triangle, which is 12x6/2=36. Since we want to know the area of the quadrilateral at the bottom of the big triangle seperated by the 2 marker point, we subtract 16 from 36, which equals to 20. 20/36=5/9. And that is my final answer. I tested it and it is correct. I hope this helps.

Students who won the lottery to students who lost the lottery
Step-by-step explanation:
Suppose a state institutes a voucher program. Schools that have too many applicants use a lottery to randomly determine who can attend.
The best approach to determining the effect of a voucher on student achievement is to compare the achievement of students who won the lottery to the achievement(s) of students who lost the lottery.
