What is the completely factored form of this polynomial? 81x4 - 16/A
A. (3x2 + 2y?)(9x+47)(9x - 4y)
B. (9x2 + 4y?)(9x2 - 4y?)
C. (9x2 + 4y713x – 2y12
D. (9x + 4y)(3x+27)(3x – 2y)

i dont understand the question? ?

step-by-step explanation:

85.560%

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
