Given:
The data set is 13, 14, 15, 6, 17, 16, 3.
To find:
The mean absolute deviation for the data set.
Solution:
We have,
13, 14, 15, 6, 17, 16, 3
Mean of the data set is:
[tex]\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]
[tex]\overline{x}=\dfrac{13+14+15+6+17+16+3}{7}[/tex]
[tex]\overline{x}=\dfrac{84}{7}[/tex]
[tex]\overline{x}=12[/tex]
The formula for mean absolute deviation is:
[tex]MAD=\dfrac{\sum_{i=1}^n|x_i-\overline{x}|}{n}[/tex]
Using this formula, the mean absolute deviation for the data set is:
[tex]MAD=\dfrac{|13-12|+|14-12|+|15-12|+|6-12|+|17-12|+|16-12|+|3-12|}{7}[/tex]
[tex]MAD=\dfrac{1+2+3+6+5+4+9}{7}[/tex]
[tex]MAD=\dfrac{30}{7}[/tex]
[tex]MAD\approx 4.29[/tex]
Therefore, the mean absolute deviation for the data set is about 4.29.

The Fudd family is attending a family reunion. They plan to rent a
car from the ABC Car Rental Company. Let m represent the number
of miles the family will drive. Let c represent the cost for renting a
car. Complete problems
The complete problem equation will be c = k*m + b
The cost equation for renting a car from the ABC Car Rental Company in terms of the number of miles driven, m, and the cost, c, would likely take the form of:
c = k*m + b where k is the rate of cost per mile and b is the fixed cost for renting the car independent of the miles driven.
It is important to note that this is a general equation and the specific cost equation of the ABC Car Rental Company is not provided. Also, this equation assumes that the cost of renting a car is linear to the miles driven, which may not be the case in practice. Other factors such as the type of car and duration of the rental period could also be included in the cost equation.
Therefore, the problem equation will be c = k*m + b

Each key feature can be used more than once, but not all key features will be used.
Which key features are present in these three functions?
Answer:
See screenshot attached that shows it is correct
Step-by-step explanation:
f(x) has a domain of (-infinity, 6) U (6, infinity). Horizontal asymptote of y= -2
g(x) has a domain of (-infinity, -3) U (-3,2) U (2,infinity). Horizontal asymptote of y=1.
h(x) has a domain of (-infinity, 6) U (6, infinity). Function has a oblique asymptote.
The function [tex]f(x)=\dfrac{\left(-2x+4\right)}{x-6}[/tex] will have a domain of [tex](-\infty,6)\cup(6,+\infty)[/tex], the function [tex]g(x)=\dfrac{\left(x^{2}-2x\right)}{x^{2}+x-6}[/tex] will have a domain of [tex](-\infty,-3)\cup(-3,2)\cup(2,+\infty)[/tex], and the function [tex]h(x)=\dfrac{\left(x^{2}-2x\right)}{x-6}[/tex] will have a domain of [tex](-\infty,6)\cup(6,+\infty)[/tex].
Given information:
The given functions are:
[tex]f(x)=\dfrac{\left(-2x+4\right)}{x-6}[/tex]
[tex]g(x)=\dfrac{\left(x^{2}-2x\right)}{x^{2}+x-6}[/tex]
[tex]h(x)=\dfrac{\left(x^{2}-2x\right)}{x-6}[/tex]
For a rational function, the denominator should not be equal to zero.
So, the domain of the first function will be,
[tex]x-6\neq0\\x\neq6\\(-\infty,6)\cup(6,+\infty)[/tex]
The function [tex]f(x)=\dfrac{\left(-2x+4\right)}{x-6}[/tex] will form a vertical asymptote at [tex]x=6[/tex].
The domain of the second function will be,
[tex]x^2+x-6\neq0\\x^2+3x-2x-6\neq0\\(x+3)(x-2)\neq0\\x\neq2, -3\\(-\infty,-3)\cup(-3,2)\cup(2,+\infty)[/tex]
The function [tex]g(x)=\dfrac{\left(x^{2}-2x\right)}{x^{2}+x-6}[/tex] will form a vertical asymptote at [tex]x=-3[/tex] and a horizontal asymptote at [tex]y=1[/tex].
The domain of third function h(x) will be,
[tex]x-6\neq0\\x\neq6\\(-\infty,6)\cup(6,+\infty)[/tex]
Now, the third function [tex]h(x)=\dfrac{\left(x^{2}-2x\right)}{x-6}[/tex] will form an oblique asymptote, and a vertical asymptote at [tex]x=6[/tex].
The graph of each function is attached to the image.
Therefore, the function [tex]f(x)=\dfrac{\left(-2x+4\right)}{x-6}[/tex] will have a domain of [tex](-\infty,6)\cup(6,+\infty)[/tex], the function [tex]g(x)=\dfrac{\left(x^{2}-2x\right)}{x^{2}+x-6}[/tex] will have a domain of [tex](-\infty,-3)\cup(-3,2)\cup(2,+\infty)[/tex], and the function [tex]h(x)=\dfrac{\left(x^{2}-2x\right)}{x-6}[/tex] will have a domain of [tex](-\infty,6)\cup(6,+\infty)[/tex].

Rearrange x = 3g + 2 to make g the subject
Answer:
[tex]g=\frac{x}{3} -\frac{2}{3}[/tex]
Step-by-step explanation:
You divide 3 from both sides leaving you with g=(x/3)-(2/3)
Please mark my answer as brainlyest.
The value of g can be rearranged by the expression x = 3g + 2 is [tex]\dfrac{x-2}{3}[/tex].
A collection of constants, variables or numbers connected using one or more arithmetic operator is called an expression
Example = 4y, 3x+4.
Given expression:
x = 3g + 2
Subtract 2 from both the sides:
x-2 = 3g + 2-2
x-2 = 3g
Divide both side by 3 to get the value of g
[tex]\dfrac{x-2}{3} = g[/tex]
Thus, the rearrangement of the expression x = 3g + 2 in the form of g is [tex]\dfrac{x-2}{3}[/tex].

∠A and \angle B∠B are upplementary angle. If \text{m}\angle A=(7x-11)^{\circ}m∠A=(7x−11)
∘
and \text{m}\angle B=(x-25)^{\circ}m∠B=(x−25)
∘
, then find the meaure of \angle B∠B
The measure of ∠B is (x - 25)° = (27 - 25)° = 2°.
What are supplementary angles?
Supplementary angles are two angles that add up to 180 degrees. They are angles that when placed together will form a straight line. They are called "supplementary" because they "supplement" each other to form a straight angle.
When two angles are supplementary, their measures add up to 180 degrees. So, if ∠A and ∠B are supplementary, then:
m∠A + m∠B = 180
Given that m∠A = (7x - 11)° and m∠B = (x - 25)°, we can substitute these values into the equation:
(7x - 11)° + (x - 25)° = 180
Simplifying this equation by combining like terms:
8x - 36 = 180
Adding 36 to both sides:
8x = 216
Dividing both sides by 8:
x = 27
Hence, the measure of ∠B is (x - 25)° = (27 - 25)° = 2°.

Write an expression to represent the area of the shaded region in simplest from
We know that the area of a square/rectangle is the multiplication of its length by its width. We also know that this specific area does not include the blank region, therefore we need to subtract it from the area of the shaded region!
We can come up with two expressions:
Shaded Area:
[tex](5x + 2)(3x - 1)\\= 15x^2-5x+6x-2\\=15x^2+x-2[/tex]
Blank area:
[tex](x)(x+7)\\x^2+7x[/tex]
Now all we have to do is subtract the blank area's expression from the shaded area's and simplify since the question asks for the simplest form.
[tex](15x^2+x-2)-(x^2+7x)\\15x^2-x^2+x-7x-2\\14x^2-6x-2[/tex]
Therefore, your final answer should be:
14x^2 - 6x - 2
Use an inverse function to write θ as a function of x.
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanθ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{3}[/tex] , then
θ = arctan [tex]\frac{x}{3}[/tex] → C
The required inverse function would be θ = arctan x/3. The correct answer would be an option (C).
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
The right triangle is given in the question, as shown.
Using the tangent ratio, we have:
tan θ = perpendicular/base
Here, perpendicular = x and base = 3
As per the figure, substitute the values in the above ratio:
tan θ = x/3
Using an inverse function to write θ as a function of x:
θ = tan⁻¹ x/3
This can be also written as:
θ = arctan x/3
Therefore, the required inverse function would be θ = arctan x/3.

y-intercept setting x=0 in the equation.
Step-by-step explanation:
x-intercepts( y=0)

A gym offers classes for students to attend. If both the range and median number of students attending each class was 13 students, which of the following box-and-whisker plots could represent the number of students attending the classes?
Answer: C (The Last One)
Step-by-step explanation:
The answers correct because, If the range and median is 13 that means that the highest and lowest point equal 13 and the middle/the line in the graphs should be on 13. A doesn't have the line/median on 13 so it is not that answer. But B and C have the line/median on the line so we just have to check the range. The range of B is: 9, The range of C is: 13. So based off that we know that the answer is C.

Answer:
measure of 1 = 117 degrees
measure of 2 = 63 degrees
*x = 39
Step-by-step explanation:
m1 = 3 x 39 = 117
m2 = 39 + 24 = 63
117 + 63 = 180 degrees
m∠1 = 3x and m∠2 = x + 24
now,
m∠1 + m∠2 = 180° (angle made in straight line)
3x + x + 24 = 180°
4x = 180-24
4x = 156
x = 156/4
x = 39°
also, 3x = 3×39 = 117
x + 24 = 39 + 24 = 63
