Answer:

median = 17.5

Step-by-step explanation:

The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.

Data in ascending order is

8, 15, 17, 18, 19, 21

The median is between 17 and 18, hence

median = $\frac{17+18}{2}$ = 17.5

Answer:

Step-by-step explanation:

The median is the value that separates the higher half from the bottom half of the data sample (middle value).

We have

15, 8, 19, 21, 18, 17

Write from the smallest to the largest number

8, 15, 17, 18, 19, 21

We have an even number of numbers. Therefore we calculate the arithmetic mean of the two middle numbers:

8, 15, 17, 18, 19, 21

(17 + 18) : 2 = 35 : 2 = 17.5

Answer:

$\frac{3}{20}$

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is $\frac{3}{8}$ text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text = $\frac{3}{8}x$

Remaining part = $x-\frac{3}{8} x$

Remaining part = $\frac{8x-3x}{8}=\frac{5}{8} x$

Therefore, a newspaper;s cover page fill with Photograph = $\frac{5}{8}$

If the article about endangered species= $\frac{2}{5}$ of text

Therefore, the article about endangered species= $\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x$

Hence, the article about endangered species is $\frac{3}{20}$ of the cover page.
