Answer:
Hello!
In the study, there are two separate groups: "Women whose mothers took the drug DES during pregnancy" and "Women whose mothers didn't take the drug during pregnancy" these two groups represent the populations of interest.
I hope it helps!

Answer:
about 189
Step-by-step explanation:
because out of 34 is 9 so 714 divided by 34 is 21 and 21 multiply by 9 is 189.
The problem statement gives a relation between the amount removed from one bag and the amount removed from the other. It asks for the amount remaining in each bag. Thus, there are several choices for variables in this problem, some choices resulting in more complicated equations than others.
Let's do it this way: let x represent the amount remaining in bag 1. Then the amount removed from bag 1 is (100-x). The amount remaining in bag 2 is 2x, so the amount removed from that bag is (100-2x). The problem statement tells us the relationship between amounts removed:
... (100 -x) = 3(100 -2x)
... 100 -x -3(100 -2x) = 0 . . . . . . subtract the right side
... 5x -200 = 0 . . . . . . . . . . . . . . eliminate parentheses and collect terms
... x -40 = 0 . . . . . . . . . . . . . . . . .divide by 5
... x = 40 . . . . . . . . . . . . . . . . . . . add 40
- 40 kg is left in the first bag
- 80 kg is left in the second bag
_____
<u>Check</u>
The amount removed from the first bag is 60 kg. The amount removed from the second is 20 kg. The amount removed from the first bag is 3 times the amount removed from the second bag, as described.
Neither.
Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.
Rewriting the 2nd equation to solve for y,
You get:
Y=1/5x + 1/2
The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.
Hope that helps!
