Answer:
4) 0
5) 30.5 and 60.5
6) 30.5 through 80.5
Step-by-step explanation:
The box plot is split into 4 parts, the first 25% of it (1/4 of 100) is 0.
Q stands for quarter (1/4) so Q1=30.5 because of where the first dot hits, and Q3=60.5 because of where the 3rd dot hits.
The dot plot goes from 30.5 through 80.5.
I hope this makes sense and helps you!

Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?
your x value is your slope so the slope is 6 and your y intercept is the y value so your intercept is 3
hope this helps
