f(x)= - 3x^3 - 6x^2 + 3x + 6
graph the function. show your work with the following: fundamental theorem of algebra to know how many roots you’ll discover; descartes rule of signs to determine how many will be positive, negative or imaginary; rational root theorem to know the possible roots; and synthetic division with upper and lower bounds to find the roots.
f(x)=-3x^3-6x^2+3x+6

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
