(1)
we are given
U is the midpoint of RS
and we have
so, we can use formula
we can plug values
............Answer
(2)
V is the midpoint of ST
so, we get
now, we can plug values
divide both sides by 2
.........Answer
(3)
now, we can find y
W is the midpoint of TR
so, we get
we can plug value
divide both sides by 3
(4)
we can see that
triangles URW and RST are similar
so, their sides ratios must be equal
so, we get
we can plug values
...........Answer
(5)
we can see that
triangles SUV and RST are similar
so, their sides ratios must be equal
so, we get
now, we can plug values
.............Answer

Step-by-step explanation:
1. It is the subset of a group - Group sample.
2. It equally favors all members of a group sample
- Random sample.
3. It collects data on members of a group - Survey.
4. It does not equally favor all members of a group - Biased sample.
5. It includes all members of a group
- Population.

I have matched all concepts in accordance with statistical use, hope it helps.
That's a funky problem... :/ I mean it would depend on how much she earns weekly. If she were working 40 hours each week and earning 10$ an hour then yes, she would have enough. Even is she were per say a student on a part time working 30 hours and earning 8$ per hour, she would still have enough.
Consider triangle XYZ with vertices at points X(1,-3), Y(3,0) and Z(-1,-1). If triangle XYZ is reflected across the line y = 1, then the rule of reflection is
(x,y)→(x,-y+2).
The image X' of point X will have coordinates according to the given rule:
X(1,-3)→X'(1, -(-3)+2)=X'(1,5).
Answer: correct choice is D.
