Past records indicate that 15 percent of the flights for a certain airline are delayed. Suppose flights are randomly selected on
1 answer:
Answer:
a. 0.0783
Step-by-step explanation:
For each flight, we have these following probabilities:
A 15% probability that a flight is delayed
An 85% probability that a flight is on time.
Which of the following is closest to the probability that it will take 5 selections to find one flight that is delayed?
This is the probability that the first four flights are on time and the fifth is late. So
So the correct answer is
a. 0.0783

Answer:
A. 60 degrees
Step-by-step explanation:
Solution to sin(x/2)=(/2)
By looking at this equation, I can identify that the answer must be within the first quadrant since the numerator and denominator are both positive.
Since it is in the first quadrant, the range of the value of the answer must be between 0 degrees less than or equal to x less than or equal to 90 degrees.
I can also identify that this is a 30, 60, 90 degree triangle because it has a and 2 as the numerator and denominator; in this case this tells us that we are dealing with a 30, 60, 90 degree triangle because that is the only triangle with those 2 respective sides.
Once identifying those two pieces of information, we can then determine the answer.
Since sin is equal Opposite/Hypotenuse, we can then substitute the sides of the triangle (, 2) to find the angle (unknown).
So the equation would look like this,
Sinx/2=/2 (
representing the opposite side of the angle; 2 representing the Hypotenuse of the triangle)
We can then conclude that 60 degrees is the unknown angle, due to the nature of a 30 60 90 degree triangle.

Therefore, the answer, 60 degrees, is a solution to the equation "sin(x/2)=(/2)"
