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.

Find the 12th term of the geometric sequence 4, 8, 16, ...
Answer:
2^(n+1)
1st term ----> n=1 = 2^(1+1) = 2^2 =4
2nd term ----> n=2 = 2^(2+1) = 2^3 =8
3rd term ----> n=3 = 2^(3+1) = 2^4 =16
like this,

What is the great GCF (Greatest Common Factor)?
24x^2 and 20x
First, determine the greatest common factor between the numbers.
Remember, the greatest common factor is just the largest
factor that divides evenly into the two numbers.
In this case, 4 is the largest number so the GCF of our numbers is 4.
For the variables, however, we use the smallest power.
Since we have an x and an x², we use an x.
So our GCF is 4x.

Answer:
y=x+10
Step-by-step explanation:
y=mx+b
y=1x+b
1 because for every 10 it goes to the right, it goes up 10 as well.
b=10 because the function crosses the y-axis at 10
so
y=x+10

What is the slope of the line shown below?
Answer:
A. 2
Step-by-step explanation:
Formula for slope of a line (m) = change in y / change in x = ∆y/∆x
Using the coordinates of two points on the line, (1, -4) and (6, 6):
Slope (m) = (6 - (-4)) / (6 - 1) = 10/5 = 2
Slope (m) = 2

Shopping Two friends shop for fresh fruit. Jackson buys a watermelon for $7.25 and 5 pounds of cherries. Tim buys a pineapple for $4.15 and 4 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Jackson spent.
Answer:
Given:
Elena buys a watermelon for $8.25 and 4 pounds of cherries
Tania buys a pineapple for $4.15 and 3 pounds of cherries
Variable "p" represents the price (in dollars) per pound of cherries
To find:
Write an expression to represent the amount that Elena had spent more than Tania
Solution:
Variable "p" ← is the price of the cherries per pound
The price of cherries bought by Elena will be = $ 4p
∴ Total amount spent by Elena during her shopping for fresh fruits is,
= $ 8.25 + $ 4p
= $ [8.25 + 4p]
Also,
The price of cherries bought by Tania will be = $ 3p
∴ Total amount spent by Tania during her shopping for fresh fruits is,
= $ 4.15 + $ 3p
= $ [4.15 + 3p]
Now, we will find that how much more than Tania, Elena had spent during her shopping for fresh fruits, i.e.,
= [Total amount spent by Elena on fresh fruits] - [Total amount spent by Tania on fresh fruits]
= [8.25 + 4p] - [4.15 + 3p]
= 8.25 + 4p - 4.15 - 3p
= $ [4.10 + p]
Thus,
4.10+P
