mean- 8, 7, 9, 10, 10, 12, 14

8+7+9+10+10+12+14 = 64

Mode- 8, 7, 9, 10, 10, 12, 14
Since mode is the most common number 10 should be the mode.

Median- 8, 7, 9, 10, 10, 12, 14
Since there's not two middle numbers the middle number is 10.



To get the square root of 25 we have to find out what multiplied by what gives you 25. so we find out that 5x5=25. So we know that the square root has to be 5.



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

Taking 15% off then 10% off is different than taking 25% off because....

15% off of $100 is $15
10% off of $85 is $8.50
Total saving of $23.50

25% off of $100 is $25

You save $1.50 off of $100 taking 25% off instead of 15% off than an additional 10%.
