When you solve the slope intercept of x + 2y = 16, and get the slope of -0.5, where does the -x come from when switching from standard to y = mx + b form? I attempted doing the problem using this:
x + 2y = 16 ---> 2y = x + 16

But apparently the correct equation to use is:
2y = -x + 16

So where does -x come from if the x is positive?

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

divide 150 by 100

divide 100 by 1.5

there you go!
