The solutions to the inequality y s 2x - 4 are shaded on the graph. Which point is a solution?
(-1, 1)
(1, -1)
(3, 2)
(2, 3)

Step-by-step explanation:

Refer to the attached figure.  Note that the solution set is shaded, and includes all points on the solid boundary line.

black point (-1,1) is outside of the solution set

Red point (1,-1) is also outside of the solution set.

Yellow point (3,2) is on the solid boundary line, so it is part of the solution set

Blue point (2,3) is outside of the solution set.

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
