Answer:
30 flights are expected to be late.
Step-by-step explanation:
Consider the provided information.
A Department of Transportation report about air travel found that nationwide, 76% of all flights are on time.
That means 100-76% = 24% of all flights are not on time.
125 randomly selected flights.
We need to find flights would you expect to be late.
Flight expect to be late E(x) = nq
Here n is 125 and the probability of late is 24 or q = 0.24
Thus substitute the respective values in the above formula.
Flight expect to be late E(x) = 125 × 0.24 = 30
Hence, the 30 flights are expected to be late.
Y = 0.8
4x + 8y = 40
4x + 8*(0.8) = 40
4x + 6.4 = 40
4x = 40 - 6.4
4x = 33.6
x = 8.4
