  • quartiles
  • medians
  • ranges

is given below:

<h3>What is Box and Whisker plots?</h3>

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 80

  • 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 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.

AnnZ [28]

Answer:

4V = 3U

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

Let us assume that the final cost of the sale item is V and the price on the tag is given by U.

Then the equation that best describes the function that represents the situation is V = \frac{75U}{100} =\frac{3U}{4}

⇒ 4V = 3U  (Answer)

? Liter equivalent to 0,000 000 000 013 cubic kilometers
Amiraneli [1.4K]

<em><u>Question:</u></em>

? Liter equivalent to 0.000 000 000 013 cubic kilometers

How do we do it?´

<em><u>Answer:</u></em>

13 liter is equivalent to 0.000 000 000 013 cubic kilometers

<em><u>Solution:</u></em>

Given that,

? Liter equivalent to 0.000 000 000 013 cubic kilometers

So we have to convert cubic kilometer to liter

<em><u>Use the following conversion factor</u></em>

1\ km^3 = 1000000000000\ liter

Therefore,

0.000 000 000 013\ km^3 = 0.000 000 000 013 \times 1000000000000\ liter\\\\0.000 000 000 013\ km^3 = 13\ liter

Thus, 13 liter is equivalent to 0.000 000 000 013 cubic kilometers
