Answer:
11+(2+y)
Step-by-step explanation:
The associative property says that you can move numbers inside the parentheses around if all the numbers are the same operation in a simple sense
So that means in this case: 2+(11+y)
We can switch the 2 and the 11 around since they are both the same, addition.
11+(2+y)
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.
The product of the sum of the their rates and the time it took them to finish the job should be equal to one whole job. This may be expressed by the equation,
(1/9 + r) x 6 = 1
Solving for the value of r gives an answer of r = 1/18. Thus, Hector does 1/18 of the job in 1 hour.
