What is the slope of the line that passes through points (-4, 5) and (3, -2)?

-1

Step-by-step explanation:

Complete y2 - y1 over x2 - x1 with your given points:

-2 - 5     =        -7

3 - (-4)    =        7

= ⁻⁷⁄₇ = -1   Simplify to lowest term

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
