 * Mean-** 12.83
 * Median**-14
 * Mode**-4

1. Make sure that your data set is in numerical order. 4,4,12,16,19,22

2. To find the mean add up all of the numbers then divide by the amount of pieces of data. 4,4,12,16,19,22 = 12.83

3.To find the median just find the number in the middle which are 12 and 16. So add them together then divide by 2. 12+16=28/2= 14

4. The mode is the number that shows up the most. It is 4.

 * What is the square root of 41?**

Is taking 15% off a given item and then an additional 10% off the reduced price the same as taking 25% off the the original price?
 * Why or why not?**

It would not be the same. For example say I bought a 20 dollar item then took off 10% 0.10 X 20 =2.0$ 20$ - 2$= 18$ This means i have to pay 18$. Then if I took off an additional 15% 0.15 X 18 =2.7 18$ - 2.7$= 15.3$ So if i took off 10% an item then an additional 15% i have 15.3$

But if I took 25% off a 20 dollar item I would have dollars. 0.25 X 20 =5 20$ - 5$= 15$ Taking 25% off a 20$ item would make 15$. If i took 10% off a 20$ item then an additional 15% off an item I would have 15.30$.
