Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high. The dispersion of the data around the mean value is measured by the standard deviation. It might be helpful when comparing data sets that may have the same mean but a different range. The means of the two numbers 15, 15, 15, 14, 16, and 2, 7, 14, 22, 30 are the same, for instance. The second, though, is unmistakably wider.

What is an angle bisector?

An angle bisector is a line or segment that divides an angle into two congruent angles. It is called an angle bisector because it bisects, or cuts in half, the measure of the angle. An angle bisector can also divide the angle into two angles of different measures if the angle is not congruent.

In order to find x, we can use the Angle Bisector Theorem which states that the ratio of the length of the segment from the vertex of the angle bisector to the sides of the angle is equal to the ratio of the length of the other two segments formed by the angle bisector.

In this case, we know that QT is an angle bisector of angle X, so we can set up the following proportion:

(ST/x) = (TR/XT)

We are given that ST = 21, TR = 32 and XT = 18

Solving for x:

x = (21*18) / (32+18) = 378 / 50 = 7.56

Hence, Rounding to the nearest tenth: x = 7.6

The scale factor used in the dilation of the triangle ABC is 3.

Dilation is a method for generating analogous figures decreasing or increasing their dimensions by some scaling factors.

By dividing distances by the scale factor, each point is stretched outward from the central point D if the scaling factor is more than 1 or inwards if the scale factor is less than 1.

Considering the triangle ABC:

The length of the side AB is 2 units

Compared with triangle DEF, the length of the similar side DE is 6 units

The scaling factor = length of side DE /length of the side AB

The scaling factor = 6 / 2

The correct statement is (D) at every vertex.

The vertex of a triangle is the intersection of two sides. Vertices is the term used to describe objects with several vertices.

The ability to write an equation for a line given two points is a prerequisite. The intersection of two lines will then need to be solved, which will give you the intersection's coordinates.

One of the triangle's vertices is at this intersection of two lines.

So, we know that 4 triangles are joined to make them horizontal.

This can be done when the vertex is attached to all 4 triangles.

The correct option is (B) The line that can be drawn through points D and E is contained in plane Y.

A point is a location in space. It has neither shape nor size. A line is a connected set of points that extends infinitely in two directions. A plane can be defined by three noncollinear points, two parallel lines, or two intersecting lines.

The planes X and Y and points C, D, E and F are shown in the given figure.

We are to select the TRUE statement about the points and the planes.

We know that, if two points lie in a plane, then the line drawn through the points will contain in the same plane.

The points C lies outside the plane Y and the point D lies on the plane Y, so the line drawn through the points C and D will not contain in plane Y.

So, option (A) is NOT correct.

The points D and E, both lie in the plane Y, so the line drawn through the points D and E will also contain in plane Y.

So, option (B) is CORRECT.

Since the plane X contain infinitely many points, so F is not the only point that can lie in plane X.

So, option (C) is NOT correct.

Similarly, there are infinitely many points in the plane Y, so the points D and E are not the only points that can lie in plane Y.

So, option (D) is NOT correct.

The graphical representation that would be most appropriate for the data, given the number of different breakfast cereals sold, is B. Histogram, because there is a large set of data.

Histograms are used for large sets of data because they provide a visual representation of the distribution of the data. They are particularly useful for understanding the distribution of continuous variables, such as measurements or time series data.

One of the main advantages of histograms is that they allow for easy comparison of large sets of data. The use of bars to represent the data makes it easy to see the overall shape of the distribution and identify patterns or outliers. Additionally, histograms can be used to compare multiple sets of data at once, allowing for easy comparison of different groups or changes over time.

Another advantage of histograms is that they can be used to identify the underlying probability distribution of a dataset, which is useful for statistical analysis and modeling.
