Step-by-step explanation:
A real estate agent in the coastal area of Georgia wants to compare the variation in the selling price of homes on the oceanfront with those one to three blocks from the ocean. A sample of 21 oceanfront homes sold within the last year revealed the standard deviation of the selling prices was $45,600. A sample of 18 homes, also sold within the last year, that were one to three blocks from the ocean revealed that the standard deviation was $21,330. At the .01 significance level, find the F-value. Leave your answer in 2 decimal places
Answer:
The F-value is approximately 4.57
Step-by-step explanation:
The given parameters are;
The number of oceanfront homes in the sample, n₁ = 21 homes
The standard deviation of the selling prices, s₁ = $45,600
The number homes in the sample of homes one to three blocks from the ocean, n₂ = 18 homes
The standard deviation, s₂ = $21,330
The level of significance, α = 0.01
The F-test is given as follows;
[tex]F = \dfrac{s_1^2}{s_2^2}[/tex]
Therefore, we get;
F = 45,600²/21,330² ≈ 4.57
The F-value ≈ 4.57
The critical value from the F-table = 1.86236.
In this exercise we have to use the knowledge about force to calculate the critical force, in this way we find that:
[tex]F-value: 4.57[/tex]
We know that the information given by the text is:
The number of oceanfront homes in the sample: [tex]n_1 = 21 homes[/tex] The standard deviation of the selling prices: [tex]S_1 = $45,600[/tex] The number homes in the sample of homes one to three blocks from the ocean: [tex]n_2 = 18 homes[/tex] The standard deviation: [tex]S_2 = $21,330[/tex] The level of significance: [tex]\alpha= 0.01[/tex]The F-test is given as follows:
[tex]F=(S_1^2)/(S^2_2)[/tex]
So we have:
[tex]F=(45.600^2)/(21.330^2)=4.57\\[/tex]

im horrible at math so can some one write down the value to x
Answer:
x = 134 degrees
Step-by-step explanation:
The two angles are alternate interior angles, therefore they equal.
I hope this helped!
It can definitely be a bit tricky to remember all of the different types of angles! But let's see what we've got here.
Our given measures/variables, 134 and x, are both on the inside of the parallel lines (clue: INTERIOR). Then, we can see that they are on opposite sides (clue: ALTERNATE). Therefore, these are alternate interior angles.
Alternate interior angles are congruent, which means that x = 134 degrees.
Hope this helps!! :)

Answer:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
Triangle with angle X
50+70=120180-120=60X=60°To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
60+50=110180-110=70Blank angle=70°We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!

Answer:

Answer:
9cm
Step-by-step explanation:
a square has 4 equal sides, so to find out the area you do width x height
the area is 81cm², which means that the side length is 9cm as 9 x 9 = 81

99% + 99% - 99% × 99% ÷ 99%
Add 99% and 99%198% + 99% - 99% × 99% ÷ 99%
Divide 99% × 99% by 99%198% - 99%
Subtract 99% from 198%99%

Step-by-step explanation:
99% + 99% - 99% × 99% ÷ 99%
Add 99% and 99%
198% + 99% - 99% × 99% ÷ 99%
Divide 99% × 99% by 99%
198% - 99%

The foundation of a house has 1200 termites. The termites grow at a rate of about 3% each day. How many termites are there after one week (round to the nearest termite?
Answer:
1476 termites after 7 days.
Step-by-step explanation:
initial population, P = 1200
rate of growth, r = 1.03
time, t = 7 days
Final population
= Pr^t
= 1200 (1.03^7)
= 1475.8
You roll a 6-sided die.
What is P(odd)?
i need someone to explain this to me please.
Write your answer as a percentage.
Answer:
50%
Step-by-step explanation:
In total, there are six things that can happen when you roll a 6-sided die: you either roll a 1, 2, 3, 4, 5 or a 6.
Three of these numbers are odd, therefore meaning the chances of you rolling an odd number is [tex]\frac{3}{6}[/tex] (because there are 6 events which could occur, 3 of which are odd)
Converting this into a fraction can be made easier by simplifying the fraction. As both the numerator and denominator can be divided by 3, you can simplify the fraction to [tex]\frac{1}{2}[/tex]
To turn this into a percentage, first divide 100% by your denominator (2) to get 50%, and then multiply it by your numerator (1). Therefore, P(odd) is 50%.

A line goes through the points (8,9) and (-2,4)
(B) Write the equation of the line in point-slope form. Show your work.
Please only answer if you know the answer.
Please explain. :)
Answer:
[tex]\displaystyle y-9=\frac{1}{2}(x-8)\text{ or } y-4=\frac{1}{2}(x+2)[/tex]
Step-by-step explanation:
Point-slope form is given by:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where (x₁, y₁) is a point and m is the slope.
So, first, we will find the slope using the two points (8, 9) and (-2, 4). We can use the slope formula:
[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{4-9}{-2-8}=\frac{-5}{-10}=\frac{1}{2}[/tex]
Next, pick either of the two points and substitute it into the point-slope formula. Using (8, 9), we acquire:
[tex]\displaystyle y-9=\frac{1}{2}\left(x-8\right)[/tex]
And using (-2, 4), we acquire:
[tex]\displaystyle y-4=\frac{1}{2}\left(x -(-2)\right)\Rightarrow y-4=\frac{1}{2}\left(x+2\right)[/tex]
Both of these are valid answers.
Answer:
y-9=1/2(x-8)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-9)/(-2-8)
m=-5/-10
m=1/2
y-y1=m(x-x1)
y-9=1/2(x-8)
