Here are the answers for the mean, median, and mode mommy and pappi:

__**1.) 4, 10, 3, 9, 9, 17, 6, 7**__


 * Make sure to put it in numerical order:**

__**3,4,6,7,9,9,10,17**__

__Mean:__ 3 + 4 + 6 + 7 + 9 + 9 + 10 + 17= 65/8 = 8.125 __Mode:__ It is the number 9.

__Median:__ 9+9=18 18/2=9 9 is the median




 * __2.) What is the square root of 43?__**

Look for a number closest to 43 that can be multiplied by 2 of the same numbers which is 36 (6x6). Then look for the next closest one thats larger than 43, 49 (7x7). Use the 2 numbers and subtract them 49-36 = **13**.

__**36**__ , 37, 38, 39, 40, 41, 42,  __43__  , 44, 45, 46, 47, 48,   __**49**__

use the square root of 36 which is 6 in your fraction. Then you count the numbers after 36 until you get to 43 which is 7. 7 is your numerator. **13** is the denominator. So, your fraction is 6 and 7/13.


 * __3.) Is taking off 10% and then taking an additional 40% off the same as just taking 50% off? Explain your reasoning.__**

Yes, it is the same because if your taking off 10 percent and then another 40 percentits exactly the same. (ex. 10 + 40 = 50 is what your taking off)


 * __4.) If you got 75% on a math test and you know the test is out of 40, then what is your score out of 40?(use ratio tables to figure this out or an X | K | Y chart)__**

This is what it should show if you can't read this: under P: 75 / 5=15 / 5=3 x 10=30 under T: 100 / 5=20 / 5=4 x 10=40

30 is your score out of 40.

__**5.) What is your percentage if you got 35/50 on your test? Use fractions to solve this answer.**__

P/T =35/50= ?/100

35 / 50 = 0.7

__0.7 x 100= 70%__

35/50 = 70/100

the factor : 35 x 2=70 and 50 x 2= 100

__P/T__ =35/50= 70/100 or 70%

Here are the last of your questions. I hope you guys had a hard time figuring this out. haha just kidding XP
