Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots =

</h2>
Step-by-step explanation:
The number of students participated = 30
Total audience = 150
By probability , to find the solution =
where n(E) is the number of favorable outcomes,
n(S) is the number of total outcomes.
n(S) is the number of ways any 8 students can by picked from the audience= 
n(E) is the probability of picking four students from our school and five students from another school.
n(E) =
= 
=
= 
The first one would be 9 and 1/3
the second one would be 27
To find the line of best fit, you use the equation y=mx+b which is the form of a linear equation. in order to find m, your slope you use the equation m=(y2-y1)/(x2-x1).
the answer should be
c. y=45/14x
