Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

2, 2, 25, 25, 26, 26, 27, 28, 28, 30
Minimum: 2
Maximum: 30
Median: 26
Lower quartile: 25
<span>Upper quartile: 28</span><span>
The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.</span>
