Answer:
He made a reasonable inference.
Step-by-step explanation:
Rodriguez asked 60 randomly chosen students about their favorite types of reading materials.
Of those 60 students, 12 chose science fiction.
In percent this is about 
%
Mr. Rodriguez drew an inference that about 20% of middle school students prefer to read science fiction.
We can see that this inference is correct. He made a reasonable inference as his sampling was non biased and completely random.
Answer:
Step-by-step explanation:
Find the slope = -2/1
Find the y-intercept = 5
Go to graph
put a dot at (0,5)
since it's a negative slope you will go up 2 and left 1
draw your line
_________________________________________________
Find the slope = 3/1
Find the y-intercept = 0
go to graph
Put a dot at (0,0)
Since it is a positive slope you will go down 3 and left 1.
To find the slope and y-intercept use this formula=
y=mx+b
m=slope
b=y-intercept
I'm sorry I don't know how to do a check equation for these.

Answer:
4
Step-by-step explanation:
Area=pi (radius^2) Plug in numbers.
206=3.14 (r^2) Divide both sides by 3.14
65.61=r^2 Then square root both sides.
8.1ft =r Then round to the nearest foot.
r=8ft
