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.
Answer:
x is approximately 48.2.
Step-by-step explanation:
Use the trig function of cosine, or adjacent over hypotenuse.
cos theta = adjacent / hypotenuse
Substitute variables.
cos x = 10 / 15
Apply inverse cosine to both sides.
x = cos^-1(10/15)
Evaluate.
x ≈ 48.2
Answer:
Step-by-step explanation:
2x + 4 = 6x - 10
Minus 2x on both sides
4 = 4x - 10
Add 10 on both sides
14 = 4x
Divide by 4 on both sides
14/4 = x
x = 14/4
Simplify fraction
x = 7/2 or x = 3 1/2
