An airline has 81% of its flights depart on schedule. It has 69% of its flights depart and arrive on schedule. Find the probability that a flight that departs on schedule also arrives on schedule. Round the answer to two decimal points.

Given:

81% flight departs on schedule

69% flight departs and arrive on schedule

Probability that a flight that departs on schedule also arrives on schedule.

Probability that flight departs on schedule * Probability that flight arrives on schedule = Probability that flight departs and arrives on schedule

0.81 * x = 0.69

x = 0.69 / 0.81

x = 0.8519 or 85.19%

The probability that a flight that departs on schedule also arrives on schedule is 85.19%.

Step-by-step explanation:

the answer is b to that quesiton

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2
