The addition of the outlier will affect the distribution in that b) The distribution will become skewed left.
Why is the skew left ?When a score of 12 is added as an outlier, it shifts the distribution of data towards the left-sided direction resulting in skewness. This can be deduced from observing that the median is closer to the lower end of the range of collected data.
Additionally, the introduction of the outlier has substantially decreased the mean value, indicating that the deviation value has pulled the mean downwards and altered the symmetry of the original distribution by making it asymmetrically distributed in a leftward manner.

package. How many notepads did Ms. Garcia
buy in all?
Answers
3•5=15

9+15+24=48
Answer: red = 9, yellow = 15 green = 24, total = 48 notepads were bought.
Step-by-step explanation:
3 x 3 = 9, so 9 red. 3 x 5 = 15, so 15 yellow. 3 x 8 = 24, so 24 green. In total this is equal to 48 notepads. 9 + 15 + 24 = 48.
Given the function g(x) = -x² − 9x + 27, determine the average rate of change
of the function over the interval -9 ≤x≤-1.
Answers
The rate of change of the function g(x) in the interval -9 ≤ x ≤ -1 is 1
How to determine the rate of change?The rate of change of a function y = f(x) on the interval [a, b] is given by the formula below:
R = (f(b) - f(a))/(b - a)
Here the function is g(x) = -x² − 9x + 27 and the interval is [-9, -1], we can evaluate g(x) in both ends of our interval, then we will get the two values needed for the numerator, here we will get:
g(-1) = -(-1)² − 9*-1 + 27 = -1 + 9 + 27 = 35
g(-9) = -(-9)² -9*-9 + 27 = 27
Replacing that in the formula we can get the rate of change is:
R = (35 - 27)/(-1 + 9) = 8/8 = 1

The radius of Circle A is 8 mm. The radius of Circle B is 5 mm greater than the radius of Circle A. The radius of Circle C is 4 mm greater than the radius of Circle B. The radius of Circle D is 3 mm less than the radius of Circle C. What is the area of each circle? How many times greater than the area of Circle A is the area of Circle D?
Answers
Area of Circle A = π(8 mm)^2 ≈ 201.06 mm^2
Moving on to Circle B, we know that its radius is 5 mm greater than the radius of Circle A, which means:
Radius of Circle B = 8 mm + 5 mm = 13 mm
Using the same formula, we can find the area of Circle B:
Area of Circle B = π(13 mm)^2 ≈ 530.93 mm^2
Proceeding to Circle C, we know that its radius is 4 mm greater than the radius of Circle B, which means:
Radius of Circle C = 13 mm + 4 mm = 17 mm
Using the same formula, we can find the area of Circle C:
Area of Circle C = π(17 mm)^2 ≈ 907.92 mm^2
Finally, for Circle D, we know that its radius is 3 mm less than the radius of Circle C, which means:
Radius of Circle D = 17 mm - 3 mm = 14 mm
Using the same formula, we can find the area of Circle D:
Area of Circle D = π(14 mm)^2 ≈ 615.75 mm^2
To find how many times greater the area of Circle D is compared to the area of Circle A, we can divide the area of Circle D by the area of Circle A:
Area of Circle D / Area of Circle A ≈ 3.06
Therefore, the area of Circle D is approximately 3.06 times greater than the area of Circle A.

This has to do with the solution the quadratic equation given as: y=x² - 5x -14.
What is the solution and related quantities?
To factorize the quadratic equation - y = x² - 5x -14, we need to find two numbers that multiply to -14 and add up to -5.
We can list out the factors of -14 as follows:
-1 and 14
1 and -14
-2 and 7
2 and -7
Out of these pairs, the numbers that add up to -5 are -2 and 7.
Therefore, we can factorize the equation as:
y = (x - 2)(x + 7)
To find the zeros or x-intercepts, we set each factor equal to 0 and solve for x:
x - 2 = 0, x + 7 = 0
x = 2, x = -7
So the solutions are (2, 0) and (-7, 0).
The axis of symetry is the average of the x-intercepts
This is (2 - 7)/2 = -2.5.
Substituting this value into the equation:
y = (-2.5 )² - 5 (-2.5 ) - 14 = - 20.25
So the vertex is ( -2.5, -20.25).
The domain of the function is all real numbers, since there are no restrictions on the input x.
The range of the function is y ≥ -20.25, since the vertex is the lowest point of the parabola and the graph extends upward from there. See the graph attached.

Answers
Based on the information provided dilate triangle ABC by a scale factor of 3, with point D as the center of dilation.
To perform a dilation, each point in the original figure is transformed by multiplying its coordinates by the scale factor and then translating the figure according to the center of dilation. In this case, each point in triangle ABC will be multiplied by a scale factor of 3, with point D as the center of dilation.
To dilate the triangle by a scale factor of 3, you can follow these steps
Draw rays from point D to the vertices of triangle ABC.Measure the distance between each vertex and point D. This distance will be the radius of the dilation.Multiply the x-coordinate and y-coordinate of each vertex by 3, since the scale factor is 3.Use the measured distances as a guide to draw the dilated triangle, with each vertex located at the end of a ray from point D.Hence, if the scale factor is greater than 1, the dilated figure will be larger than the original. If the scale factor is between 0 and 1, the dilated figure will be smaller than the original. If the scale factor is negative, the figure will be reflected across the center of dilation.

The ratio of the speeds of pulleys is inversely proportional to the ratio of their diameters. The speed reduction required on a pulley and belt drive is 4 to 1. If the drive is 4 inches in diameter, what size would be required for the driven pulley?
Answers
1 inch is the diameter of the driven pulley.
Let's use D to represent the driven pulley's diameter. The speed decrease needed, according to the issue description, is a 4 to 1 reduction.
This implies that the ratio of the diameters is also 4 to 1, as the speeds are inversely proportional to the diameters:
D/4 = 1/4
Multiplying both sides by 4 gives:
D = 1

The above expression is a sine function of 310 degrees
By mathematical expression, we have
