F(x)=x+2 g(x)=3x^2-5 find (f x g)(x)

(f · g)(x) = 3x³ + 6x² - 5x - 10

General Formulas and Concepts:

Step-by-step explanation:

Step 1: Define

f(x) = x + 2

g(x) = 3x² - 5

Step 2: Find (f · g)(x)

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
