How to find the median

KengaRu [80]

We can find the median by using the formula:

(N+1/2) th item

For example:

Given data: 4,6,3,5,7

We have to arrange the data into ascending order:

=3,4,5,6,7

N(total no of items)=5

Now,

Median=(N+1/2)th item

 =(5+1/2) th item

 =(6/2) th item

 = 3rd item

Median=5

Hope it helps

A shirt was marked down 25% which means you saved $15. What was the original cost of the shirt? What is the new price?

wlad13 [49]

60 dollars. You multiply 15 four times because 25% of the cost is 15 so you multiply it by 4 to get the total answers.

Open-Ended Question *Picture*

My name is Ann [436]

We have to calculate the volume of the right rectangular prism.
lenght=4 1/2 in=(4+1/2) in=9/2 in
width=5 in
height=3 3/4 in=(3+3/4) in=15/4 in

Volume (right rectangular prism = lenght x width x height.
volume=9/2 in * 5 in * 15/4 in=675/8 in³

we calculate the volume of this little cube.
volume=side³
volume=(1/4 in )³=1/64 in³

Now, we calculate the number of small cubes are needed to fit the right rectangular pris by the rule of three.

1 small cube----------------1/64 in³
x---------------------------------675/8 in³

x=(1 small cube * 675/8 in³) / 1/64 in³=5400 small cubes.

Answer: we need 5400 small cubes to fit the right rectangular prism.
