Answer:
a) Attached
b) P=0.60
c) P=0.80
d) The expected flight time is E(t)=122.5
Step-by-step explanation:
The distribution is uniform between 1 hour and 50 minutes (110 min) and 135 min.
The height of the probability function will be:
Then the probability distribution can be defined as:
b) No more than 5 minutes late means the flight time is 125 or less.
The probability of having a flight time of 125 or less is P=0.60:
c) More than 10 minutes late means 130 minutes or more
The probability of having a flight time of 130 or more is P=0.80:
d) The expected flight time is E(t)=122.5
Answer:
<u>18 waves</u> hit the beach in 49 s.
Step-by-step explanation:
Given:
The frequency of the waves that were coming into the beach is 0.367347 Hz.
Now, to find the number of waves that hit the beach in 49 s.
Let the number of waves be
The frequency of waves () = 0.367347 Hz.
The time it takes to hit the beach () = 49 s.
Now, we put formula to get the number of waves:
<u><em>The number of waves = 18.</em></u>
Therefore, 18 waves hit the beach in 49 s.
