I mean my best answer would be using common sense and go with 20% since there is only 80% mentioned in the question

Please Help!! much appreciated! :D<br><br> Find the value of y.
Ksivusya [100]

In the largest triangle, the missing side has length

√((11 + 5)² - <em>x</em> ²) = √(256 - <em>x</em> ²)

But it's also the hypotenuse of the triangle with side lengths 11 and <em>y</em>, so that its length can also be written as

√(11² + <em>y</em> ²) = √(121 + <em>y</em> ²)

so that

√(256 - <em>x</em> ²) = √(121 + <em>y</em> ²)

or, by taking the squares of both sides,

256 - <em>x</em> ² = 121 + <em>y</em> ²

<em>y</em> ² = 135 - <em>x</em> ²

In the smallest triangle, you have

5² + <em>y</em> ² = <em>x</em> ²   ==>   <em>x</em> ² = 25 + <em>y</em> ²

Substitute this into the previous equation and solve for <em>y</em> :

<em>y</em> ² = 135 - (25 + <em>y</em> ²)

<em>y</em> ² = 110 - <em>y</em> ²

2<em>y</em> ² = 110

<em>y</em> ² = 55

<em>y</em> = √55

HELP PICTURE IS SHOWN!!!
Liono4ka [1.6K]
Each outlier in a box plot is symbolised by a "dot". So there can be two possible answers since there are two different outliers in each end of the box plot (5 and 73): either C or D. 

The line in the middle of the boxes is equal to the median. If you find the median, you can approximately determine where the middle-line is, and choose whether C or D is is best fit.
