F(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
Answer:
31/40
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 270, number of total outcomes = 1200
Probability (the number of people from the suburbs attending the concert is 270) = 270/1200 = 9/40
Probability (the number of people from the suburbs attending the concert is fewer than 270) means that the number of people from the suburbs attending the concert is not 270 = 1 - 9/40 = (40-9)/9 = 31/40
