Answer:
0.0159
Step-by-step explanation:
Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.
Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)
The plane is overbooked if more than 150 show up
i.e. less than 2 do not show up
Hence the probability that the airline overbooked this flight
=
The sum of all angles in a triangle has to be 180 so
180-90-73=17
The other non right angle is 17
Answer:
- 76.7 million
- 89.1 million
- 75 million
Step-by-step explanation:
Let x represent the arrivals and departures at the third airport. Then the number at the first airport is x+1.7, and the number at the second airport is x+14.1. The total is ...
(x+1.7) + (x+14.1) + (x) = 240.8
3x +15.8 = 240.8
3x = 225
x = 75
x+1.7 = 76.7
x+14.1 = 89.1
The first airport has 76.7 million arrivals.
The second airport has 89.1 million arrivals.
The third airport has 75 million arrivals.
