Small press publishes an unpredictable number Xof newbooks each month with probability generating function휋"푞=퐸푞"='()*+(,*).//a) Each book they publish in a given month has an 80% chanceof reaching a best-seller list. What is the probability that next month allthe books they publish will reach the best-seller list? (Hint: remember the post-testinterpretation of p?)b) Calculate the expected value and variance of the number of books they will publish next month.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
