Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.3 per year. a. Find the probability that in a year, there will be 3 hurricanes. b. in a 45-year period, how many years are expected to have 3 hurricanes ? c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?
Answer:
a) 0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.
b) 5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.
c) 5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
The mean number of hurricanes in a certain area is 5.3 per year.
This means that [tex]\mu = 5.3[/tex]
a. Find the probability that in a year, there will be 3 hurricanes.
This is P(X = 3).
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = x) = \frac{e^{-5.3}*5.3^{3}}{(3)!} = 0.12386[/tex]
0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.
b. in a 45-year period, how many years are expected to have 3 hurricanes ?
0.12386 each year. So, for 45 years:
45*0.12386 = 5.57
5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.
c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?
5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.

For degrees F
Add triangles have a angle sum of 180
So you just subtract 180 by the angles in the triangle
180 - 91 = 89
89 - 43 = 46
46 is remaining so it is the missing degrees ( F )

Find the domain of f(x)= x/x-9
Answer:
Step-by-step explanation:
The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is
x=(-oo, 9),(9, +oo)
49 is 160% of what number?
Answer:
x = 30.63
Step-by-step explanation:
Answer:
30.63
Step-by-step explanation:
We have, 160% × x = 49
or, 160/100 × x = 49
Multiplying both sides by 100 and dividing both sides by 160,
we have x = 49 ×
100/160 x = 30.63
If you are using a calculator, simply enter 49×100÷160, which will give you the answer.

There are a total of 120 counters in a box.
There are only red counters and blue counters in the box.
There are three times as many red counters as blue counters in the box.
Carl takes
1
of the red counters from the box.
3
Kerry takes 80% of the blue counters from the box.
Work out the ratio of the number of red counters to the number of blue counters now in the
box.
Give your ratio in its simplest form.
Answer:
The ratio of red to blue would be 60: 6 which can be simplified to 10:1.
The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1
What is ratio ?Ratio is the comparison of two quantities in terms of same units.
Example : If a & b be two numbers, then the ratio is a/b, where b≠0
What is the required ratio ?Let Blue counters = x
Red counters would be = 3 times of blue counters = 3x
There are a total of 120 counters in a box.
First we have to find, the number of red and the number of blue counters:
3x + x = 120
⇒ 4x = 120
⇒ x = 120/4
⇒ x = 30
There are 30 blue counters.
Red counters = 3×30 = 90
Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.
Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.
The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.
