Let /(20) = 3x - 1 and 9(9) 22 +3 and find g(/(x)) Select the correct response
9($(x)) = 5x + 2
9(f(x)) = 6x + 8
9(f(x)) = 6x + 1
9($(x)) = 5x - 4

6x + 1

Step-by-step explanation:

g(f(x))

f(x) = 3x - 1

g(f) = 2x + 3

= 2(3x - 1) + 3

= 6x - 2 + 3

= 6x + 1

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
