The correct answer is D. Sample, because the collection of the number of cars for 10 households is a subset of all households in the neighborhood.
The data set "The number of cars for 10 households in a neighborhood of 30 households" is a sample.
A sample is a subset of a larger population, and in this case, the data set represents information from only 10 out of the 30 households in the neighborhood. It is not an exhaustive collection of all households in the neighborhood, but rather a smaller group selected from the larger population.
Option D is the correct answer: "Sample, because the collection of the number of cars for 10 households is a subset of all households in the neighborhood."
To further clarify, a population would encompass all households in the neighborhood, while a sample represents a smaller group of households within that population. In this case, the data set provides information from a limited number of households, making it a sample rather than a complete representation of the entire neighborhood.

What is the equation for the line in slope-intercept form?
Answer: y = 8x
Step-by-step explanation:
The line passes through points (1,8) and (2,16).
Using this, we can first find the slope.
Slope = Δy/Δx = 8/1 = 8
So the slope is 8.
The equation is now
y = 8x + b
Let's use the point (1,8) to find the value of b now.
8 = 8 +b
b = 0
Therefore, y = 8x is the answer.
(you can skip the last step by noticing that the graph passes through the origin)
Answer:
y = 8x
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
From inspection of the given graph, two points on the line are:
(0, 0)(2, 16)Substitute the points into the slope formula to find the slope of the line:
[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.
Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:
[tex]\implies y=8x+0[/tex]
[tex]\implies y=8x[/tex]
Therefore, the equation for the line in slope-intercept form is:

Write a quadratic equation in standard form that has an axis of symmetry of x=-2and y intercept of 0,6
The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.
A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.
The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.
To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.
By using above two information, we can write the quadratic equation in standard form as:
a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0
So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

What is circle ?All points on a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
The following is a list of a circle's attributes:
A closed 2D form that isn't a polygon is a circle. It has one face that curves.If two circles have the same radius, they are said to be congruent.Equal chords are always located equally from the circle's center.The center of the circle is the perpendicular bisector of a chord.The line joining the points of two overlapping circles will be perpendicular to the line joining the points of the circles' centers.The tangents drawn at the diameter's endpoints are perpendicular to one another.Look closely at the above illustration; if we divide the circle into smaller pieces and arrange them in a particular order, a parallelogram will result. The circle progressively becomes the shape of a rectangle as it is split into smaller and smaller segments. The likelihood that it will have the above-illustrated rectangle form increases with the number of parts it has.

Explain why Mary is mistaken in her conclusions about ΔABC and ΔXYZ. In writing your response, be sure to explain the difference between similarity and congruence. Also be sure to include important math concepts such as similarity, proportionality, and corresponding sides.
Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.
In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.
It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.
In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.

The value of 0.55 hectometers expressed in decimeters is 550 decimeters. The result is obtained by using the concept of unit ladder system.
How the unit ladder method works?The common length units are kilometers to milimeter. The conversion can be described in a unit ladder system as follows.
km (kilometers)
hm (hectometers)
dam (decameters)
m (meters)
dm (decimeters)
cm (centimeters)
mm (millimeters)
Every time the length unit goes down, it is multiplied by ten. Every time the length unit goes up, it is divided by ten.
We have 0.55 hectometers. Express that value in decimeters!
From hectometers to decimeters, it goes down 3 times. So,
0.55 hectometers = 0.55 × 10 × 10 × 10 decimeters
0.55 hectometers = 0.55 × 1000 decimeters
0.55 hectometers = 550 decimeters
Hence, 0.55 hectometers is equal to 550 decimeters.

The vertices of the polygons are given as B(−2, 2), C(4, −2), D(4, 4) . The polygon is reduced by using a scale factor one fourth. i.e 1/4.
This means that each coordinates of the vertices will be reduced by 4 to give the vertices of the new polygon.
A = (-4,6) , A' = ( -1, 1.5)
B = ( -2,2) B' = ( -0.5, 0.5)
C = ( 4, -2) C' = ( 1, -0.5)
D = ( 4,4) , D' = ( 1, 1)
Therefore the vertices of the new polygon is A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1)

Answer:

Step-by-step explanation:
A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left.
If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.
To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:
slope = (y2 - y1) / (x2 - x1)Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.
In this case:
y2 = 224 (goats left after 11 months)y1 = 280 (goats left after 7 months)x2 = 11 (months)x1 = 7 (months)So the slope of the line is:
slope = (224 - 280) / (11 - 7)slope = -56 / 4 slope = -14The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.
It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.
This question is incomplete and should be written as:
A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left.

What is the full table of 5?
A "full table of 5" refers to a multiplication table that includes all of the products of the number 5 multiplied by the integers from 1 to some maximum value.
Write the complete table of 5.Here is an example of a full table of 5:
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50
In this example, the maximum value for the multiplier is 10, but a full table of 5 can continue with any number of rows. This table is useful for memorizing the multiplication facts of 5, and also to see the pattern of the multiples of 5.
It's worth to mention that if you are looking for a way to calculate the products you could use a loop or a function that takes the maximum value of the multipliers as an input and prints the full table of 5.
