Line ab contains points a(4, 5) and b(9, 7). what is the slope of ab?

Step-by-step explanation:

We know that slope of a line that passes through P(a,b) and Q(c,d) is given by :-

Given points : A(4, 5) and B(9, 7).

Then, the slope of line AB that contains points A(4, 5) and B(9, 7) is given by :-

Hence, the slope AB =

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
