Answer:
Step-by-step explanation:
Given:
To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting from the left and move it to the right. We then get:
Now, we have y isolated. We now have to remove the 4 from the y. The only way to do this is divide both sides by 4. We then get our final answer:
We can clean this up by putting it in a common form, slope-intercept form:
Answer:
0.211 = 21.1% probability that 2 flights of BlueSky Air arrive late
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either they arrive late, or they do not. The probability of a flight arriving late is independent of any other flight. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
BlueSky Air has the best on-time arrival rate with 80% of its flights arriving on time.
This means that 100 - 80 = 20% are late, which means that
Randomly selecting 16 BlueSky Air flights
This means that
What is the probability that 2 flights of BlueSky Air arrive late?
This is P(X = 2).
0.211 = 21.1% probability that 2 flights of BlueSky Air arrive late
