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

Lulu wants to get fit. She started with 50 laps a day and she intends to add 10 laps every week. Write a mathematical expression
vlabodo [156]

Answer: 10x + 50

Step-by-step explanation:

lets say that x is equal to the amount of weeks that she runs. She starts off the first week with 50

Then, since she is adding 10 every week, you would do 10x, or 10 times the amount of weeks that she runs.

Since you originally started with 50, you have to add the 50 to the 10x.

So you get...

<h3>10x + 50</h3>

For example

on week 2, if you plug in 2 to x you get

10(2) +50

20 + 50

70 laps after the second week
