Assume that a study of 500 randomly selected airplane routes showed that 482 arrived on time. Select the correct interpretation of the probability of an airplane arriving late. Interpret an event as significant if its probability is less than or equal to 0.05.
Answer: We are given that out of 500 randomly selected airplanes, 482 arrived on time.
Therefore, the probability of airplane being on time 
And the probability of airplane being late

Since the probability of airplane being late is 0.036, which is less than 0.05, therefore the event is significant at 0.036
Answer:
Step-by-step explanation:
y∞x
then
y=kx (with k as constant)
y=5 when x=8
⇒Putting this in the first equation
⇒5=k×8
⇒k=5/8
Now
y=? when x=64
Putting x=64 in the first equation
y=kx
⇒y=(5/8)×64
We get
y=40
Hope u understand
Answer:
$200
Step-by-step explanation:
Half of $800 is $400, and a quarter of $800 is $200. $800-$400-$200=$200
Answer: 2x²-√3
Step-by-step explanation:
Another way to say the conjugate is the opposite. All you have to do is to change the sign in the binomial, which is 2x²+√3. When you change the sign, it becomes 2x²-√3.
