Answer:
Step-by-step explanation:
<u>Given:</u>
- Rate per hour = $6
- Number of hours = 5
- Tips = 15%
Lets the total amount of tabs = t
<u>We have inequality:</u>
- 6*5 + 0.15t ≥ 350
- 30 + 0.15t ≥ 350
- 0.15t ≥ 320
- t ≥ 320/0.15
- t ≥ 2133.33
Part A: 65/90 because you take the given number of positive test and put it over the total number of test.
Part B: it’s dependent because it depends on the negative to get the probability/likely hood.
