The dimensions of the carpet are 73 x 43. = 3139.
What is dimension explained?In mathematics, a dimension is a way to quantify the size or separation of an area, an object, or a space inside one direction. In simpler terms, It is just the measurements of an object's length, width, and height.
What is a geometric figure?Geometric figures can be created using any configuration of points, lines, or planes. Depending on their dimensions, geometric figures can be categorized as either a space figure, a surface figure, a line, another line segment, a ray, or a point.
According to the given data:The perimeter of the carpets = is 232.
The length of the carpet = 30 in.
In a rectangle, the edge is P = 2W + 2L
In this case 232 = 2W + 2L
Also, the 2nd sentence says L = W + 30
This length variable can be changed in the perimeter formula:
232 = 2W + 2(W+30)
232 = 2W + 2W + 60
232 = 4W + 60
172 = 4W
43 = W
Then, since L = W+30
L = 43+30 = 73
So the dimensions of the carpet are 73 x 43. = 3139.

The population mean of the data is 6.
How to find the population mean?The population has n = 16 scores.
The sum of all of the scores is equal to 96.
Therefore, the population mean can be found as follows:
The population mean is the mean or average of all values in the given population.
The population mean is represented mathematically as follows:
population mean = sum of terms / number of terms
Therefore,
sum of terms = 96
number of terms = 16
Hence,
population mean = = 96 / 16

What is parabola?A symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity follows a curve of this shape. A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.
Given:
The equation of parabola in vertex form is

If m< ABF=7b-24 and m< ABE = 2b, find m< EBF .
Answer:
∠ EBF = 16°
Step-by-step explanation:
note that EB is the angle bisector of ∠ ABF , then
∠ ABE = ∠ EBF = 2x and
∠ ABF = ∠ ABE + ∠ EBF , that is
7b - 24 = 2b + 2b
7b - 24 = 4b ( subtract 4b from both sides )
3b - 24 = 0 ( add 24 to both sides )
3b = 24 ( divide both sides by 3 )
b = 8
Then
∠ EBF = 2x = 2(8) = 16°

What is the shape of the distribution for the following set of data? x f 5 5 4 3 3 1 2 3 1 5
The shape of the distribution for the following set of data is: symmetrical.
What are distributions?When we study data, one of the major ways to understand it is to think about its general form, such as whether it is symmetrical, has more numbers on one side than the other, or fits a common probability distribution like the normal, binomial, or exponential.
Now,
By looking at how the data are arranged in the table, we can tell that the distribution's form is symmetrical. With 1 item at X=3, it appears that this occurs frequently. The average was calculated using the range of data from X=1 to X=5. In addition, the data contain 5 items at X=5 and X=1, respectively. Both of these occur equally often and at equal intervals from the average. We can also say that there are three items in the data at X=4, three things at X=2, and so on, all of which are equally far from the average. As a result, every piece of data is either averaged out or counterbalanced on the other side of the average. A symmetrical distribution is described here. Therefore, it is neither favorably nor negatively biased. Even though it is symmetrical, the distribution is not normal since a normal distribution contains more data at the average than at the tails, as opposed to fewer.Hence, The shape of the distribution for the following set of data is: symmetrical.

after the sails have rotated 270° clockwise about their center of rotation. What would
be the coordinates of S?
The coordinates of S are (-4,2) .
The sails' center of rotation = Origin (0,0)
Coordinates of S on the top of one of the sails, = (2,4)
Rotation :The action or process of rotating on or as if on an axis or center.
Centre of Rotation :The center of rotation is a point about which a plane figure rotates. This point does not move during the rotation.
It is given that sails have rotated 270° clockwise.
So, When we rotate a figure of 270 degree clockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.
So, the point turn (2, 4) into (-4, 2).
Thus, the coordinates of S are (-4,2).

16. <1 and <2 form a linear pair. The
measure
of <2 is six more than twice the
of <1. Find m<2.
The measure of the angle 2 is 122°.
What is referred as the linear pair?When lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to one another after the two lines intersect, they are said to be linear. The sum of the angles of the a linear pair will always be 180°. These angles are also referred to as supplementary angles.Given that angles 1 and 2 form a linear pair,
angle 1 + angle 2 = 180 degrees —— (1)
We've also been notified that angle 2 is 6 times the size of angle 1.
That is to say: angle 2 = (2×angle 1) + 6 ———- (2)
Putting the angle 2 value in (1) from (2)
180 = angle 1 + 2×angle 1 + 6
3×angle 1 = 174
1st angle = 58 degrees ———-(3)
(1) and (3) come from:
angle 2 + 58 = 180
2nd angle = 122 degrees
As a result, angle 2 has a measure of 122 degrees.
