What is Box and Whisker plots?A box and whisker plot is defined as a graphical method of displaying variation in a set of data.
From the first figure, write all the values where dark point is drawn
53, 62, 80, 86, 89
The lower extreme is the smallest value, which is 53.The upper extreme is the highest value, which is 89.
The median will be the middle of data , which is 80The upper quartile is the median of the upper region and the lower quartile is the median of the lower region.The upper quartile is 86 and the lower quartile is 62.
Range of the data be,= Highest - Lowest
=89-53
=36
From the second figure, write all the values where dark point is drawn
56, 62, 74, 89, 96
The lower extreme is the smallest value, which is 56.The upper extreme is the highest value, which is 96.
The median will be the middle of data , which is 74.The upper quartile is the median of the upper region and the lower quartile is the median of the lower region.The upper quartile is 89 and the lower quartile is 62.
Range of the data be,= Highest - Lowest
=96-62
=34
From the above discussion,
The First class have less upper extreme value than the second class.The First class have less lower extreme value than the second class.The First class have greater median than the second class.The First class have less upper quartile than the second class.The First and second class have equal lower quartile.The First class have greater range than the second class.The comparision of the two classes on the basis of extremes, quartile, median, range is concluded above.

Hi!
Your answer is the 1st one, 36 inches of ribbon.
The question states this is a square picture frame. That means that all the side lengths are the same.
We are given a side length of 6 inches.
In order to find the area of a square, we multiply the length and the width together.
In this problem, the sides of the picture frame measure 6 inches. Therefore:
[tex]6*6=36[/tex]
For a similar problem, see:

How do you find the mean absolute deviation MAD
Answer:
Most of the time you can go on a website that can cauculate it.
Step-by-step explanation:
How to cauculate the MAD:
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

7:21=10:3z
find the value of x in this ratio
Answer:
z=10
Step-by-step explanation:
We know that the ratio 7:21 is equal to the ratio of 10:3z.
Let's model that in proportions:
7 10
- = -
21 3z
Now that the equation is in proportional form, we can cross-multiply to find the value of z.
7 * 3z = 21 * 10 - Multiply both sides
21z = 210 - Divide both sides by 21
z=10
The answer is z=10.

Solve 4n^2+8n = -15 by completing the square.
Use a comma to separate multiple values.
Answer:
No Solutions
Step-by-step explanation:
First to complete the square, it will need to look something like
a^2+2ab+b^2
so in order to get that we can see that 4n^2+8n seems to be missing a piece.
a is the square root of 4n^2 which is 2n.
8n/2n=4
4/2=2
b=2
so now add 2 to both sides of the equation so now it's
4n^2+8n+4=-13
rewrite as (2n+2)^2=-13
Now you see a negative number as the result of a exponent.
A number squared will never be negative.
Therefore the answer is
