My question: Find the mean, median and mode for the following set of numbers:
8, 4, 3, 3, 5, 7

Mean: 8+4+3+3+7+8 30 30/6

5==

Median: 3, 3, 4, 5, 7, 8 4+5=9 9/2=4.5

Mode: 3

What is the square root of 38?

The square root of 52 is 7 3/15

Is taking off 15% off a given item and then an additional 10% off the reduced price the same as taking 25% off the original price? Why or why not?
No it is not the same.You take off more by just taking off 25%.
Example:
10% of 100 is 10
15% of 90 is 6
25% of 100 is 75
1. If 40 CDs cost $20, calculate the cost of 20 CDs. Use a word ratio and fractions.

A child can run 5 blocks in two minutes. How long does it take the child to run 15 blocks, at the same speed? Use a ratio table.
It takes the child six minutes.
