Answer:4
Step-by-step explanation:
You multiply each term by each term when expanding double brackets, so:
-2x × 9x = -18x^2
-2x × -3y = 6xy
8y × 9x = 72xy
8y × -3y = -24y^2
Now you combine the like terms to get
-18x^2 + 78xy - 24y^2
I hope this helps!
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.
