What is the slope of the line through (-9,6) and (-3,9)?

1/2

Step-by-step explanation:

To find the slope of a line through 2 point we use the formula

m = (y2-y1)/ (x2-x1)

    = (9-6)/(-3--9)

    = 3 /(-3+9)

    = 3 /6

    = 1/2

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
