Given A = {x | x < 1}, B = {x | x ≥ 5}, and C = {x | x = 5} Select all that are true:
A U B = {x│x < 1 or x > 5}
A ∩ B = The empty set
A U C = {x│x < 1 or x = 5}
B ∩ C = {x│x=5}
B U C = {x│x = 5}

Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

(a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?
