The IQR is the inter-quartile range. It is the length of the box in the middle of the graph. Having the long tail on the right does not affect the box. Therefore, the IQR is not affected.
Answer:
IQR
Step-by-step explanation:
Interquartile range (IQR): it's the difference between the largest and smallest values in the middle 50% of a set of data. It is not affected by the long tail in the graph because its calculation only consider the central part of data.
Range: it’s the difference between the highest value and the lowest value in a data set. It is affected by long tails because consider the whole data
Median absolute deviation (MAD): it's the median of the absolute deviations from the data's median. It's moderate affected by long tails because atypical measures give greater absolute deviation that may cause a greater MAD.

If volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that volume of a right rectangular shipping carton is 948.75 cubic meters.
The height of the shipping carton is 11 meters, and the width is 7.5 meters.
We have to find the length of the shipping carton
V=Length × width × height
V= Length x 7.5 x 11
948.75 = 82.5 length
Divide both sides by 82.5
Length = 948.75/82.5
Length = 11.5 meters
Hence, if volume of a right rectangular shipping carton is 948.75 cubic meters and the height of the shipping carton is 11 meters, and the width is 7.5 meters then length is 11.5 meters.

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that 20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building
We need to find the angle which the ladder make with the ground.
tan(x) = opposite side / adjacent side
In this case, the opposite side is the height of the building, which is 20 feet.
The adjacent side is the distance from the wall to the base of the ladder, which is 8 feet.
Plugging in the values:
tan(x) = 20 / 8
x=tan⁻¹(20/8)
x=63.43 degrees
x is the angle
Hence, the ladder makes an angle of 63.43 degrees with the ground.

4(2.1k - 4) = 6(3.4k - 2); apply the distributive property to remove the parenthesis.
8.4k - 16 = 20.4k - 12; Get the variable to one side, so subtract 8.4k.
-16 = 12k - 12; isolate the variable by adding 12.
-4 = 12k; divide by 12 to solve for our variable.

-x+y=5 4x+y=10 Use addition to solve the linear system of equations. Include all of your work in your final answer
Answers
x = 1
y = 6
Explanation:
The first given equation is:
-x + y = 5
Multiply this equation by -1, you will get:
x - y = -5 ............> I
The second given equation is:
4x + y = 10 ..........> II
Add the two equations I and II as follows:
x - y = -5
+ 4x + y = 10
..............................
5x = 5
Therefore:
x = 5/5
x = 1
Substitute with x in equation I to get y as follows:
x - y = -5
1 - y = -5
y = 1 + 5
y = 6

Hello
In geometry an interior angle or an internal angle is an angle formed by two sides of a polygon that sharing a common end is contained within the polygon, and the sum of these angles is given by
sum=(n-2)*180°
where n is the number of sides of the polygon,in our case n= 3 (a triangle)
Step 1
find the sum o internal angles
sum=(3-2)*108°
sum=1*180°
(1)sum=180°
step 2
find x
now, according to the graph the sum of internal angles is
sum(graph)=6x+2x+2x
(2)sum=10x
(1) must be equal to (2)
180°=10x
isolating x
x=18
Step 3
find C
by the graph ,we know
C=2x
and x=18
replacing
C=2(18)
C=36°

what is yhe best approximation of the value of w?
A) 1.4 cm
B) 4.0 cm
C) 6.0 cm
D) 7.3 cm
Answers
B) 4.0 cm
ExplanationFirst, we can adapt the law of sines to the notation of our triangle:
[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]
Now, we can infer from our diagram that [tex]W=39[/tex], [tex]U=31[/tex], and [tex]u=3.3[/tex], so we can replace the values in our previous expression:
[tex]\frac{sin(W)}{w} =\frac{sin(U)}{u}[/tex]
[tex]\frac{sin(39)}{w} =\frac{sin(31)}{3.3}[/tex]
Finally, we can solve for [tex]w[/tex]:
[tex]\frac{3.3sin(39)}{w} =sin(31)[/tex]
[tex]3.3sin(39)=wsin(31)[/tex]
[tex]\frac{3.3sin(39)}{sin(31)} =w[/tex]
[tex]w=\frac{3.3sin(39)}{sin(31)}[/tex]
[tex]w=4.03224[/tex]
Which rounds to [tex]w=4.0[/tex]
We can conclude that the best approximation of w is 4.0 cm

As we are looking for the perimeter of the polygon, we should understand the formula for each figure. For #2, we can clearly see that we have a square, which concludes that the perimeter for the figure is going to be 4S ('S' being the length of one side as all sides are equal).
Let's apply this to our problem.
P = 4S;
S = 6x + 3; set this up as an equation.
P = 4(6x + 3); apply the distributive property to the right side of the equation.
P = 4(6x) + 4(3);
P = 24x + 12
As we can see above, the perimeter of the square in problem #2 is going to be 24x + 12.
