Which inequality is represented by this graph?

y≤-1/3x+1

Step-by-step explanation:

Rise/run, aka the slope, would be 1/3 because you move down/up one, and to the side 3. It is -1/3 because the line is going up to down.

Since the y-intercept is 1, you would be adding 1 to the end of the equation.

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
