Answer:

n=9/4

Step-by-explanation:

Equate the equation to zero

n+3-5n+6=0

Collect like terms

n-5n+3+6=0

-4n+9=0

Add 4n to both sides

9=4n

Divide both sides by 4

n=9/4

Answer:

George believes the Art Club students at his school have an unfair advantage in being assigned to the art class they request. He

Whitepunk [10]

Answer:

class assignment seems to discriminate against Art Club members

Step-by-step explanation:

The probability of getting the requested assignment given that the student was in Art Club was ...

P(got class | art club) = P(got class & art club)/P(art club)

P(got class | art club) = (100/500)/(165/500) ≈ 60.6%

P(got class | not club) = P(got class & not club)/P(not club)

P(got class | not club) = (265/500)/(335/500) ≈ 79.1%

It looks like George's theory may be incorrect, as a significantly greater percentage of non-club students got their requested class than did club students. The class assignment process and art club membership are not independent, suggesting an unfair disadvantage for club students.
