Answer:
Some unit fractions can be written as a sum of two different unit fractions in more than one way. Here are the ways to write 1 6: 1 6 = 1 7 + 1 42. 1 6 = 1 8 + 1 24. 1 6 = 1 9 + 1 18. 1 6 = 1 10 + 1 15. ( 1 6 = 1 12 + 1 12, but this has a repeat so it doesn't count.)

A cruise ship has a large, circular window. It has a radius of 6 meters. What is the window's area?
Answer:
The area of the window is approximately 112.1 meters^2
Step-by-step explanation:
The formula to find the area of a circle is A=πr^2
A = πr^2 = π · 6^2 ≈ 113.09734
A ≈ 113.1
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

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.

a model for a famous statue is 2 1/2 inches tall. The actual statue is 3 1/3 feet tall. What is the ratio of the height of the model to the height of the actual model in simplest form?
Answer:
Ratio [Model : Actual] = 1:16
Step-by-step explanation:
Given:
Height of model = [tex]2\frac{1}{2}[/tex] inches = 5/2 inches = 2.5 inches
Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet
Find:
Ratio [Model : Actual]
Computation:
Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet
Height of actual status = [10 / 3] x 12
Height of actual status = 40 inches
Ratio [Model : Actual] = 2.5 / 40
Ratio [Model : Actual] = 1:16

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.
