Well, the picture is cut off below choice-C, and the whole thing is
very confusing to try and read because of trying to do all of your
work in the holes and spaces around the choices. So I'm just
going to ignore all of that, take the question, and work with it.
-- price of one book = k
-- total income if 1 book is sold = 1 · k
-- total income if 2 books are sold = 2 · k
-- total income if 100 books are sold = 100 · k
-- number of books for sale = 2b
-- total income if they're all sold = 2b · k
-- actual number that were sold = (2b - y)
-- actual total income = (2b - y) · k
the equation would be k(2b-y): he has 2b books, they sell for k each--> k*2b, but y books did not sell for k, so it's now k(2b-y)
the answer is A but I hope you understand the process now.

y=3-2cos(3x+pi)
Answers
The 3 isn't part of the function's amplitude ... the function wiggles between 2 under it
and 2 over it.
The period of the function is the change in 'x' that adds (2 pi) to the angle.
When x=0, the angle is pi
When the angle is (3 pi) . . .
3 pi = 3x + pi
2 pi = 3x
x = 2/3 pi The period of the function is 2/3 pi .
When x=0, the function is cos(pi) rather than cos(0).
So the function is a cosine with a phase shift of +pi.
It could also be described as a sine with a phase shift of -pi/2 or +3pi/2 .
Josh believes the Spanish club students at his school have an unfair advantage in being assigned to the Spanish class they request. He asked 500 students at his school the following questions: "Are you in the Spanish club?" and "Did you get the Spanish class you requested?" The results are shown in the table below. Received Spanish class requested 265 100 365 Total 335 165 500
Did not get Spanish class requested 70 65 135
Help Josh determine if all students at his school have an equal opportunity to get the Spanish class they requested. Show your work and explain your process for determining the fairness of the class assignment process.

So he asked 500 students for the questions:
The result was
=> got the Spanish class = 265 100 365
=> did not = 70 65 135
=> The total was 335 165 500
Thus, this show that only 335 students were able to get the Spanish class they requested and there are still 165 students do not received any Spanish class.
Thus, this is not fair to the other students.
Answer:
We have the given the data of 500 students and it is required to see whether every student got an equal opportunity to get the Spanish class they requested.
Now, we have,
Number of students in the Spanish class who got the class they requested = 265
Number of students not in the Spanish class that got the class they requested = 100
Total number of students in Spanish class = 335
Total number of students not in Spanish class = 165
Therefore, we get that,
Probability of students in the Spanish class who got the class they requested = = 0.791
Probability of students not in the Spanish class who got the class they requested = = 0.606
This shows that all students do not get the equal chance of getting into the Spanish class they requested.
