Answer:
- At least 10 hours
- No more than 7 feet
- At least $7.5
- More than 3 players
Step-by-step explanation:
1.
- 20x + 100 ≥ 300
- 20x ≥ 200
- x ≥ 200/20
- x ≥ 10
At least 10 hours
2.
- 2(8 + x) ≤ 30
- 8 + x ≤ 15
- x ≤ 15 - 8
- x ≤ 7 feet
No more than 7 feet
3.
- 8x + 20 ≥ 80
- 8x ≥ 60
- x ≥ 60/8
- x ≥ 7.5
At least $7.5
4.
- 3(p + 3) > 18
- p + 3 > 18/3
- p + 3 > 6
- p > 6 - 3
- p > 3
More than 3 players
Answer
Yes
Step-by-step explanation:
(8 roundtrips)(89 miles)(28 days) = 19,936
Y=1x+3
Using point slope form y=mx+b

D) She did not use a random sample, and she tried to show cause and effect with an observational study.
