Find the median of: 1, 3, 4, 6, 2, 4, 5, 6, 2, 3, 1, 4, 0, 4, 4, 4, 8, 9, 7, 4

Alborosie

Solution,

Arranging the data in ascending order:

0,1,1,2,2,3,3,4,4,4,4,4,4,4,5,6,6,7,8,9

N(total number of items)= 20

Now,

Median:

$(\frac{n + 1}{2)} ) ^{th \: item} \\ = (\frac{20 + 1}{2} ) ^{th \: item} \\ = \frac{21}{2} \\ = 10.5 \: th \: \: item$

Again,

Median:

$\frac{10 \: th \: item + 11 \: th \: item}{2} \\ = \frac{4 + 4}{2} \\ = \frac{8}{2} \\ = 4$

X + 9y = 8 x − 4y = –18

loris [4]

Step-by-step explanation:

$x + 9y = - 18 \\ 8x - 4y = - 18 \\ x = - 18 - 9y \\ 8( - 18 - 9y) - 4y = - 18 \\ - 144 - 72y - 4y = - 18 \\ - 76y = 126 \\ y = - 1.66 \\$

$x = - 18 - 9y \\ x = - 18 - 9( - 1.66) \\ x = - 18 + 14.94 \\ x = - 3.06$
