Answer:
32. ∛((x-7)/4) = f^(-1)(x)
33. -10x - 9
Step-by-step explanation:
32. We want to switch f(x) and x, and then solve for f(x) to get the inverse.
x = 4f(x)³ + 7
subtract 7 from both sides
x -7 = 4f(x)³
divide both sides by 4
(x-7)/4 = f(x)³
cube root both sides
∛((x-7)/4) = f(x)
make f(x) f^(-1)(x) because this is now the inverse
∛((x-7)/4) = f^(-1)(x)
the second answer is correct
33. for composition, we can treat (f · g) (x) as attached picture (content filter!), so we plug g(x) into f(x). This results in
2(-5x-7) + 5
expand
-10x - 14 + 5
add
-10x - 9
the second answer is correct
Answer: Our required probability is 0.515.
Step-by-step explanation:
Since we have given that
Probability that the respondents voted in favor of Scot Walker P(F) = 56%
Probability that the respondent voted in not favor of Scot Walker = 100-56 = P(F')=44%
Probability of those who did vote in favor had a college degree = 36% = P(C|F)
Probability of those who did vote against had a college degree = 44% = P(C|F')
So, we will use "Conditional Probability":
probability that he voted in favor of Scott Walker given that they had a college degree is given by
Hence, our required probability is 0.515.
