The amount $180.00 is what percent greater than $135.00?
svp [43]
It would be: 180/135 * 100 = 36/27 * 100
= 4/3 * 100
= 400/3 = 133.33

It means, 180 is 133.33% of 135. So, the difference would be: 133.33 - 100 = 33.33%

In short, Your Final Answer would be 33.33%

Hope this helps!

Find the mean,median and range of the following list of values and choose the correct result.
Aloiza [94]

Mean: 10.5

Median: 10.5

Range: 5

--------------------------------------------

<u></u>

To find the mean you order the numbers then add then divide.

<u>Add</u>

8+9+10+10+10+11+11+11+12+13=105

<u>Divide</u>

105÷10=10.5

Mean = 10.5

--------------------------------------------

<u></u>

Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.

Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.

the middle number is 10.5 so therefore it is the median.

--------------------------------------------

<u></u>

To find the range you subtract the biggest number to the smallest number.

<u>Subtract</u>

13-8=5

Therefore 5 is the range
