Same side interior angles CONVERSE also called consecutive interior angle CONVERSE.
IF (x - 30) + (x + 50) = 180 then, line line n || m.

x - 30 + x + 50 = 180
2x + 20 = 180
subtract 20 from both sides
2x = 160
divide both sides by 2
x = 80

IF (x - 30) + y = 180, then k || j.
(80 - 30) + y = 180
50 + y = 180
subtract 50 from both sides
y = 130

Two different airlines have a flight from Los Angeles to New York that departs each weekday morning at a certain time. Suppose t

marusya05 [52]

Answer: 0.8167

Step-by-step explanation:

Let E denotes the event that the first airline's flight is fully booked on a particular day, and F denotes the event that the second airline's flight is fully booked on that same day.

Given : P(E) = 0.7, P(F) = 0.6, and P(E ∩ F) = 0.49.

Then, by conditional probability formula , we have

$P(E|F)=\dfrac{P(\cap F)}{P(F)}\\\\=\dfrac{0.49}{0.6}=0.816666666667\approx0.8167$

Hence, the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked.= 0.8167
