Answer:
-2 2/7, -1 5/7, -5/7, -1/7, 5/7, 1 2/7, 2 5/7
Your answer is unlikely. That would be a 1 out of 10 chance.
3. is C, 4. is B, 5. is A, 6. is D
16.99 every 30 minutes
3 hours = 180 minutes + 45 minutes
225 minutes.
225/30 = 7.5
16.99(7.5) = 127.43
For #9 the answer would be C.
#10 would be A.
I can't figure out #11
#12 would be C.
