What is a statistical dispersion?A statistical dispersion is also referred to as degree of dispersion and it can be defined as a measure of the extent to which a numerical value (data) is likely to vary about a mean or an average value.
In Mathematics, there are four measures of dispersion for a data set and these include the following:

By applying the equation of dilation, the coordinates of the vertices of the triangle ABC are A'(x, y) = (-12, 0), B'(x, y) = (0, -9) and C'(x, y) = (-12, -9).
How to find the image of a triangle
A dilation is a type of rigid transformation. Rigid transformations are transformations applied to geometric loci such that Euclidean distances are conserved.
There is a triangle and its image must be a triangle, the new triangle is found by transforming the three vertices of the prior one following this formula:
A'(x, y) = P(x, y) + k · [A(x, y) - P(x, y)] (1)
Where:
P(x, y) - Center of reflection.A(x, y) - Original vertexA'(x, y) - New vertexk - Dilation factorIf we know that P(x, y) = (0, 0), A(x, y) = (-4, 0), B(x, y) = (0, -3) and C(x, y) = (-4, -3), then the new vertices of the triangle are, respectively:
Point A
A'(x, y) = (0, 0) + 3 · [(-4, 0) - (0, 0)]
A'(x, y) = (-12, 0)
Point B
B'(x, y) = (0, 0) + 3 · [(0, -3) - (0, 0)]
B'(x, y) = (0, -9)
Point C
C'(x, y) = (0, 0) + 3 · [(-4, -3) - (0, 0)]
C'(x, y) = (-12, -9)
Lastly, we draw the two triangles, which are presented in the image attached below.

AB is tangent to circle O at B. The diagram is not drawn to scale. If AB =15 in and AO =20, what is the length of the radius (r)? Round the answer to the nearest tenth.
The length of the radius (r) to the nearest tenth is 13.2
What is Pythagoras theorem?The theorem states that the square of the longest side is equal to the sum of the square of other two sides.
In order to determine the radius of the circle, we will use the theorem above to have:
AO² = AB² +r²
Given
AB = 15
AO = 20
Substitute
20² = 15² +r²
r² = 400 - 225
r² = 175
r = 13.2

Answer:
mean for data set 1 is 41
data set 1 MAD is 16.4
data set 2 MAD is 16.8
mean for data set 2 is 38
Step-by-step explanation:
Finding the mean:
Data set 1:formula: sum of the data set / total number of terms
sum of the data set: 18 + 29 + 35 + 58 + 65 = 205
total number of terms: there is 5 numbers in the data set
mean = 205 / 5
mean = 41
MAD (Mean Absolute Value):
step 1: Find the mean of the data (above)
step 2: Find the distance between each data and mean.
18, 29, 35, 58, 65
Distance between 18 and 41 is 23 (41 - 18 = 23)
Distance between 29 and 41 is 12 (41 - 29 = 12)
Distance between 35 and 41 is 6 (41 - 35 = 6)
Distance between 58 and 41 is -17 (41 - 58 = -17)
Distance between 65 and 41 is -24 (41 - 65 = -24)
step 3: take the absolute value of any negative numbers
|-17| and |-24| is 17 and 24
step 4: add all the distances
23 + 12 + 6 + 17 + 24 = 82
step 5: divided it by the number of data
82 / 5 = 16.4
Data set 2:
formula: sum of the data set / total number of terms
sum of the data set: 19 + 26 + 27 + 45 + 73 = 190
total number of terms: there is 5 numbers in the data set
mean = 190 / 5
mean = 38
MAD (Mean Absolute Value):
step 1: Find the mean of the data (above)
step 2: Find the distance between each data and mean.
19, 26, 27, 45, 73
Distance between 19 and 38 is 19 (38 - 19 = 19)
Distance between 26 and 38 is 12 (38 - 26 = 12)
Distance between 27 and 38 is 11 (38 - 27 = 11)
Distance between 45 and 38 is -7 (38 - 45 = -7)
Distance between 73 and 38 is -35 (38 - 73 = -35)
step 3: take the absolute value of any negative numbers
|-7| and |-35| is 7 and 35
step 4: add all the distances
19 + 11 + 12 + 7 + 35 = 84
step 5: divided it by the number of data
84 / 5 = 16.8

What is probability?The percentage of favorable events to the total number of occurrences.
The probability of spinning green will be
Toial event = 4 {R, G, B, Y}
Favorable event = 1 {G}
P(G) = 1/4
The probability of an even number on dice will be
Toial event = 6 {1, 2, 3, 4, 5, 6}
Favorable event = 3 {2, 4, 6}
P(E) = 3/6
P(E) = 1/2

Which factor pair of 36 has a sum that is - 20?
The factor pair of 36 whose sum is -20 are -2 and -18.
What are Factors?Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Let x and y be the two factors of the number 36.
Then we have,
x × y = 36
Write the factors of the number 36 as the product.
36 = 1 × 36, sum = 1 + 36 = 37
36 = -1 × -36, sum = -1 - 36 = -37
36 = 2 × 18, sum = 2 + 18 = 20
36 = -2 × -18, sum = -2 - 18 = -20
Hence the factor pair of 36 whose sum is -20 are -2 and -18.
