Answer:
The probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
Step-by-step explanation:
The probability of the complement of an event <em>E</em> is the probability of it not happening.
That is,
It is provided that the probability of American Airlines flights arriving on time (<em>X</em>) is,
P(X) = 0.803
Then the event of American Airlines flights not arriving on time is the complement of the event <em>X</em>.
Compute the probability of the complement of event <em>X</em> as follows:
Thus, the probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
Given inequality:
To find:
Which values are solutions to the inequality.
Solution:
Substitute the values in the x place.
Option A: 48
6.9 ≤ 7
Therefore 48 is one solution of the inequality.
It is true.
Option B: -5
We cannot compare a complex number and a real number.
Therefore -5 is not a solution of the inequality.
it is not true.
Option C: 50
7.07 > 7
Therefore 50 is not a solution of the inequality.
It is not true.
Option D: 49
7 ≤ 7
Therefore 49 is one solution of the inequality.
It is true.
Option E: 44
6.6 ≤ 7
Therefore 44 is one solution of the inequality.
It is true.
Option F: 2401
49 > 7
Therefore 2401 is not a solution of the inequality.
It is not true.
Therefore 48, 49 and 44 are solutions to the inequality.
