How to find the median
KengaRu [80]

<em>We </em><em>can </em><em>find </em><em>the </em><em>median </em><em>by </em><em>using </em><em>the </em><em>formula:</em>

<em>(</em><em>N+</em><em>1</em><em>/</em><em>2</em><em>)</em><em> </em><em>th </em><em>item</em>

<em>For </em><em>example:</em>

<em>Given </em><em>data:</em><em> </em><em>4</em><em>,</em><em>6</em><em>,</em><em>3</em><em>,</em><em>5</em><em>,</em><em>7</em>

<em>We </em><em>have </em><em>to </em><em>arrange </em><em>the </em><em>data </em><em>into </em><em>ascending</em><em> </em><em>order</em><em>:</em>

<em>=</em><em>3</em><em>,</em><em>4</em><em>,</em><em>5</em><em>,</em><em>6</em><em>,</em><em>7</em>

<em>N(</em><em>total </em><em>no </em><em>of </em><em>items)</em><em>=</em><em>5</em>

<em>Now,</em>

<em>Median=</em><em>(</em><em>N+</em><em>1</em><em>/</em><em>2</em><em>)</em><em>th </em><em>item</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>(</em><em>5</em><em>+</em><em>1</em><em>/</em><em>2</em><em>)</em><em> </em><em>th </em><em>item</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>(</em><em>6</em><em>/</em><em>2</em><em>)</em><em> </em><em>th </em><em>item</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em>3</em><em>r</em><em>d</em><em> </em><em>item</em>

<em>Median=</em><em>5</em>

<em>Hope </em><em>it</em><em> </em><em>helps</em>

<em>Good </em><em>luck</em><em> on</em><em> your</em><em> assignment</em>

The diagram shows a square with perimeter 20 cm.
olga_2 [115]

The percentage of the area inside the square that is shaded is 55%.

<h3>What is the perimeter of the square?</h3>

Given:

The perimeter of the square is 20Cm

Each side of the square is = 5Cm

Area = ( Length x Width )

(5 x 5) = 25 =Area

Area = 25

Area of triangle 1 = (1/2) x 5 x (5 - 3) = 5 cm²

Area of triangle 2 = (1/2) x 5 x (5 - 3.5) = 6.25 cm²

Area of shaded portion = 25 - (5 + 6.25) = 13.75 cm²

Percentage of shade portion

= (13.75 cm² / 25 cm²) x 100%

= 55%

The percentage of the area inside the square that is shaded is 55%.
