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:
130mm
Step-by-step explanation:
I'm pretty sure you mean each of the sides is this length... so I'll go off of that. 20+10+20+60+20 is the addition for this problem.
20+10+20+60+20=130 is the answer.
Answer:
x² - 20 = 0
Using the quadratic formula
a = 1 b = 0 c = -20
So we have
Hope this helps you.
ANSWER
EXPLANATION
From the mnemonics SOH-CAH-TOA.
We want to find the cosine of y
CAH means cosine ratio involves adjacent over the hypotenuse.
From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.
