The difference in housing prices in the fifth year is $7,125.
What is price?Price is the amount of money one has to pay for goods or services. It is also the return on an investment or the cost of borrowing money. Price is determined by the supply and demand of a product or service. It is also influenced by market forces such as competition, production costs, and availability of resources. Price is a key factor in determining the success of a business, as it can affect consumers' buying decisions and profitability.
$M(5) - G(5) = (1.7(5)³- 6.5(5)²+ 212) - (1.6(5)²- 14(5) + 165) = $7,125
Therefore, the difference in housing prices in the fifth year is $7,125.

How to find the variance of uniform distribution?
We can find the variance of a uniform distribution, using the following formula: Variance = (b - a)² / 12. Here: a is the lower limit of the uniform distribution, b is the upper limit of the uniform distribution.
The formula for the variance of a uniform distribution is based on the fact that the variance of a continuous uniform distribution is equal to the square of the range (i.e., the difference between the upper and lower limits) divided by 12.
For example, let's say we have a uniform distribution between 0 and 10. To find the variance, we would use the formula:
Variance = (10 - 0)² / 12
Variance = 100 / 12
Variance = 8.33
Therefore, the variance of a uniform distribution between 0 and 10 is 8.33.

What are the coordinates of the point on the directed line segment from (-1,-9) to (8,9) that partitions the segment into a ratio of 4 to 5
Answer: To find the point on the directed line segment that partitions it into a ratio of 4 to 5, we can use the formula for a point on a line given two endpoints and a ratio. The formula is:
(x, y) = (1 - t) * (x1, y1) + t * (x2, y2)
where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the line segment, and t is a value between 0 and 1 that determines the location of the point along the line.
In this case, (x1, y1) = (-1, -9) and (x2, y2) = (8, 9), and we want the point that partitions the line segment into a 4 to 5 ratio, so:
t = 4 / (4 + 5) = 4 / 9
Plugging in the values into the formula:
x = (1 - t) * x1 + t * x2 = (1 - 4/9) * (-1) + (4/9) * 8 = (5/9) * 8 - (4/9) * 1 = 44/9 - 4/9 = 40/9
y = (1 - t) * y1 + t * y2 = (1 - 4/9) * (-9) + (4/9) * 9 = (5/9) * 9 - (4/9) * (-9) = 45/9 + 36/9 = 81/9
So the point that partitions the line segment into a 4 to 5 ratio is (40/9, 81/9).

a cone is sliced such that the cross section is perpendicular to its base and the cross section intersects its vertex. what is the shape of the cross section?
The cross section is shaped like a circle.
A cone is a three-dimensional geometric object with a flat base and a smooth transition to the apex or vertex.
If a cone is sliced such that the cross section is perpendicular to its base and intersects its vertex, the cross section will be a circular shape. This is because the cross section cuts through the entire cone at a right angle, producing a circle that is defined by the curved surface of the cone and the slicing plane. The diameter of the circle is equal to the base diameter of the cone, and its center is located at the midpoint of the base.

What is a parabola?In mathematics, a parabola is a roughly U-shaped, mirror-symmetrical planar curve.
The same curves can be defined by a number of seemingly unrelated mathematical definitions, which all correspond to it.
A line and a point (the focus) are two components of one definition of a parabola (the directrix).
The directrix is not the main focus.
The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.
A right circular conical surface and a plane parallel to another plane that is tangential to the conical surface intersect to form a parabola, which is also known as a conic section.

He watched movies for one third of the time. He watched cartoons with his sister Ronnette the rest of the time. How many minutes did Ron watch cartoons? Show all work:
Ill try my best to "show my work" in text
First, we need to calculate the total amount of time Ron spent watching TV over the weekend.
On Saturday, he watched TV for 1 hour and 0 minutes from 9:30-10:30AM, 2 hours and 30 minutes from 1:00-3:30PM, and 2 hours from 8:00-10:00PM, for a total of 5 hours and 30 minutes on Saturday.
On Sunday, he watched TV for 1 hour and 30 minutes from 1:00-2:30PM, and 2 hours from 8:00-10:00PM, for a total of 2 hours and 30 minutes on Sunday.
The total time he spent watching TV over the weekend is 5 hours and 30 minutes on Saturday + 2 hours and 30 minutes on Sunday = 8 hours.
Next, we need to calculate the time he spent watching sports programs and movies.
He watched sports programs for half of the total time he spent watching TV, so he spent 8 hours / 2 = 4 hours watching sports programs.
He watched movies for one third of the total time he spent watching TV, so he spent 8 hours / 3 = 2 hours and 40 minutes watching movies.
Finally, we can calculate the time he spent watching cartoons with his sister.
He spent 8 hours watching TV total, and 4 hours watching sports programs and 2 hours and 40 minutes watching movies, so he spent 8 hours - 4 hours - 2 hours and 40 minutes = 1 hour and 20 minutes watching cartoons.
Since there are 60 minutes in an hour, the total time Ron spent watching cartoons is 1 hour and 20 minutes = 80 minutes.
Answer:
So Ron spent 1 hour and 40 minutes watching cartoons with his sister Ronnette.
Step-by-step explanation:
First, we need to calculate the total time that Ron spent watching TV. On Saturday, he watched TV for 1 hour in the morning, 2 hours and 30 minutes in the afternoon, and 2 hours in the evening, which adds up to 6 hours and 30 minutes. On Sunday, he watched TV for 1 hour and 30 minutes in the afternoon and 2 hours in the evening, which is a total of 3 hours and 30 minutes. So over the weekend, Ron watched TV for 6 hours and 30 minutes on Saturday and 3 hours and 30 minutes on Sunday, which adds up to a total of 10 hours.
Since Ron watched sports programs for half the time he watched TV, he spent 10 hours / 2 = 5 hours watching sports.
And since he watched movies for one-third of the time he watched TV, he spent 10 hours / 3 = 3 hours and 20 minutes watching movies.
Finally, we can calculate the time Ron spent watching cartoons by subtracting the time he spent watching sports and movies from the total time he spent watching TV:
10 hours - 5 hours - 3 hours and 20 minutes = 1 hour and 40 minutes
So Ron spent 1 hour and 40 minutes watching cartoons with his sister Ronnette.

Draw a triangle with vertices A(0, 4), B(2, -2), and C(-2, -2). Apply a dilation centered at the origin with scale factor to this triangle and draw the resulting triangle,A'B'C'. In complete sentences, describe the following:
a,The relationship between corresponding sides in terms of their lengths.
b.The relationship between corresponding sides in terms of their orientations.
c.The relationship between corresponding angles in terms of their measures.
a) Relationship between corresponding sides: the corresponding sides are parallel and have a ratio of k in length.
b) Relationship between corresponding sides' orientations: The corresponding sides will still be parallel to the original sides.
c) Relationship between corresponding angles:the corresponding angles are congruent.
What do you mean by congruent angles?
Congruent angles are angles that have the same measure or size. In other words, if two angles have the same number of degrees or radians, they are said to be congruent. When we say that two angles are congruent, it means that they are exactly the same shape and size, and they can be superimposed on each other without any rotation or scaling. Congruent angles play an important role in geometry, as they allow us to prove that two figures are similar or congruent.
To apply a dilation with scale factor k centered at the origin, we multiply the coordinates of each vertex by k. So, to find the coordinates of A', B', and C', we will multiply the coordinates of A, B, and C by the scale factor.
a) The relationship between corresponding sides in terms of their lengths:
Let's denote the scale factor by k. The distance between two points (x1, y1) and (x2, y2) is given by the distance formula, which is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
When we multiply each coordinate by k, the distance between the two points is multiplied by k as well. So, if AB has length dAB and A'B' has length dA'B', we have:
dA'B' = k * dAB
Similarly, we can find the relationship between the lengths of BC and B'C', as well as between the lengths of AC and A'C'.
b) The relationship between corresponding sides in terms of their orientations:
The orientation of a line is given by its slope. If two lines have the same slope, they are parallel or collinear. If they have slopes that are negative reciprocals of each other, they are perpendicular. When we multiply the coordinates of a point by k, the slope of any line passing through that point is multiplied by k as well. So, if the slope of AB is mAB and the slope of A'B' is mA'B', we have:
mA'B' = k * mAB
We can use this to find the relationship between the slopes of BC and B'C', as well as between the slopes of AC and A'C'.
c) The relationship between corresponding angles in terms of their measures:
The measure of an angle is determined by the slope of the line that contains the angle. When we multiply the coordinates of a point by k, the slope of any line passing through that point is multiplied by k as well. This means that the measure of any angle that includes the origin is unchanged by the dilation. However, the measure of any angle that does not include the origin is multiplied by a factor of k. So, if angle ABC has measure x and angle A'B'C' has measure y, we have:
y = k * x
We can use this to find the relationship between the measures of angles BAC and B'A'C', as well as between the measures of angles CBA and C'B'A'.

XYZ: side lengths of 6x−1, 5, and y+6
Enter the correct values in the boxes.
Answer: Two triangles are congruent if and only if all corresponding sides are equal in length. So, to find the values of x and y for which ΔABC and ΔXYZ are congruent, we need to equate the corresponding side lengths:
4x + 3 = 6x - 1
5 = 5
8y - 1 = y + 6
Solving the first equation for x:
4x + 3 = 6x - 1
2x = -4
x = -2
Solving the third equation for y:
8y - 1 = y + 6
7y = 7
y = 1
So, the values of x and y that make ΔABC and ΔXYZ congruent are x = -2 and y = 1.

What is cluster sampling?
Cluster sampling is a sampling technique used in statistics and research methodology where a population is divided into groups, or clusters, and a sample is randomly selected from each cluster to be included in the study.
This method is often used when it is difficult or impractical to obtain a simple random sample of individuals from a large and diverse population. For example, in a study of public schools in a state, it may be easier to randomly select a sample of schools and then include all students in those schools in the study, rather than attempting to randomly select individual students from the entire state.
The advantages of cluster sampling include lower costs and greater efficiency than other sampling techniques, particularly when working with large populations. However, it can also increase the risk of sampling bias and decrease the precision of estimates if the clusters are not representative of the larger population. Therefore, it is important to carefully choose clusters that are as heterogeneous as possible within and as similar as possible between clusters.
