Answer:
(1)14.9% (2) 2.96% (3) 97.04%
Step-by-step explanation:
Formula for Poisson distribution:
where k is a number of guests coming in at a particular hour period.
(1) We can substitute k = 7 and
into the formula:


(2)To calculate the probability of maximum 2 customers, we can add up the probability of 0, 1, and 2 customers coming in at a random hours




(3) The probability of having at least 3 customers arriving at a random hour would be the probability of having more than 2 customers, which is the invert of probability of having no more than 2 customers. Therefore:
Answer:
3/8 or 0.375
Step-by-step explanation:
0.75/2 = 3/8
The percentage of animal wasted is the number of animal wasted over 100
85.7% of the wild caught animals are wasted
<h3>How to calculate the animal wasted</h3>
From the question, we have:
Animals caught = 6 pounds
Salmon = 1 pound
The total weight in the system is:
Total = 6 pounds + 1 pound
So, we have:
Total = 7 pounds
The percent of wild caught animals wasted is then calculated as:

Simplify

Hence, 85.7% of the wild caught animals are wasted

In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.
Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.
So the unknown angle is

And that's the required answer .
