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.
Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and
Sum of values =
=
We want the value of
to give mean between 85 and 90 inclusive
Hence, the value of
is between 84 and 99 inclusive
Answer:
3x
Step-by-step explanation:
Use inverse proportion ratio: xy=k
(124)(7)=k
k=868 (this is our constant)
now substitute the constant into the inverse proportion ratio knowing the number of workers
28x=868
solve for x by dividing both sides by 28 to find the time it takes to build the house
x=31 days
so it will take 31 days for 28 workers to build the house
