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]

Answer:
Y = 9
Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
2 + 4 ( y - 1 ) = 2y + 16
step 1 distribute the 4
4 * y = 4y
4 * -1 = -4
we now have 2 + 4y - 4 = 2y + 16
step 2 combine like terms
2 - 4 = - 2
we now have - 2 + 4y = 2y + 16
step 3 add 2 to each side
-2 + 2 cancels out
16 + 2 = 18
we now have 4y = 2y + 18
step 4 subtract 2y from each side
2y - 2y cancels out
4y - 2y = 2y
we now have 2y = 18
step 5 divide each side by 2
2y / 2 = y
18 / 2 = 9
we're left with y = 9

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.
Answer:
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

Answer:
B. 6^6
Step-by-step explanation:
the fraction can be flipped to get rid of the negative exponents. this leaves you with 6^8/6^6 which is equal to 6^2. if you multiply that by 6^4 you can add the exponent values together. So you get 6^6
Answer:
6^6 (Six to the power of six)
Step-by-step explanation:
Step one: Since you are using the power over a power rule, when it comes to dividing an exponent, it gets subtracted by the one below, so that results in 6^2
Step 2: Another power rule is that when you are multiplying exponents, you are actually adding exponents, so it would end up being 6^6

The diameter of a wheel of a car is 77 cm. How many revolutions will it make to cover 242 m? (Take π≈22/ 7)
This value is approximate because pi = 22/7 is approximate.
===========================================================
Explanation:
Let's find the perimeter of the wheel, aka the circumference
C = pi*d
C = (22/7)*77
C = 242
The distance around the tire is approximately 242 cm
At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.
We can say the following
1 meter = 100 cm
242 meters = 24200 cm .... multiply both sides by 242
One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.
1 revolution = 242 cm
100 revolutions = 24200 cm ... multiply both sides by 100
---------------------------
We could also use a proportion to solve
(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)
1/242 = x/24200
1*24200 = 242x
242x = 24200
x = 24200/242
x = 100

For bases of solid figures, a lateral face is to a polygon what a lateral surface is to a circle.
What is the base of a solid figure?The base of a solid figure is one of its faces that has been distinguished from the others in some way. The solid figure is usually oriented so that the base is situated at the bottom.
What solid figure has a base of any polygon?A pyramid is a three-dimensional figure with only one base. The base can be any polygon. The other faces are triangles. A pyramid is named according to the shape of its base.

Graph BChoice C) y = 0.13x - 0.19===========================================
Explanations:
Notice how all of the points in graph B are near to a single line. This is the regression line. We don't have every point on the same line, but it's close enough. Graph A seems to suggest an exponential growth curve could work as the regression curve. Graph C seems to be randomly scattered points, so perhaps no function would work as the regression curve.I used technology to get the regression line. Specifically, I used GeoGebra. Any spreadsheet program or graphing calculator should be able to find the regression line. You can do so by hand, but I don't recommend it because it's tedious busy work in my opinion.school guidelines require that there must be at least 2 chapereones for every 25 students going on a school trip.

Which of the following is the solution to the following system of inequalities?
Let the green region represent the answer region.
x + 2y <4
3x – y > 2
Answer:
D
Step-by-step explanation:
for example point (2,0) is one of the solutions.
=> x + 2y <4
2+ 2(0) = 2 => 2< 4 (true)
=> 3x – y > 2
3(2)-0= 6 => 6>2 (true)
so, the option D is the correct one
The solution to the following system of inequalities is option D.
How to estimate the system of inequalities?There exist two inequalities drawn on a graph.
x + 2y ≤ 4 .............(1)
3x - y ≤ 2 .............(2)
Here solution set of the inequality (1) will be described by the shaded area below the solid line (in blue) characterized by "x + 2y = 4".
⇒ x + 2y < 4
⇒ x + 2y = 4
⇒ 2+ 2(0) = 2
⇒ 2< 4 (true)
(Line x + 2y = 4 will have the slope slanting down and y-intercept as 2)
Second inequality will designate the shaded area on the left of the solid red line characterized by "3x - y ≤ 2".
⇒ 3x – y > 2
⇒ 3(2)-0= 6
⇒ 6>2 (true)
(Line 3x - y = 2 will have the slope upwards and y-intercept as -2)
The solution area to these inequalities will be the common area shaded in green.
Therefore, the correct answer is option D.

7 ft., 24 ft., 21 ft.
scalene
isosceles
equilateral
not a triangle
Answer:
A
Step-by-step explanation:
Remark
The largest angle is going to be opposite the longest side. Use the Cosine Law to find the angle.
Equation
a^2 = b^2 + c^2 - 2*b*c * cos(A) and you are solving for A
Givens
a = 24
b = 21
c = 7
Solution
24^2 = 21^2 + 7^2 - 2*21 * 7 * cos(A)
576 = 441 + 49 - 294 * cos(A)
576 = 490 - 294 * cos(A)
I can see by looking at it that the angle is obtuse and the triangle is scalene.
576 - 490 = - 294 * cos(A)
86 = - 294 * cos(A)
86/-294 = cos(A)
- 0.2925 = cos(A)
A = cos-1(-0.2925)
A = 107 degrees
I just noticed that you did not have to go through all that. Sorry.

Just look at the givens. The side lengths are all different. The lengths all are larger than the two remaining lengths so D (not a triangle) is not correct.
No sides are equal, the the triangle is neither isosceles or equilateral. Both B and C are wrong.
