Always eliminate the first one before moving on. Remember to drop down monomials, like you would a normal division problem.
2x² + 10x + 18
__________________
x + 3 | 2x³ + 16x² - 12x + 9
-(2x³ + 6x²)
-------------------------------
10x² - 12x
-(10x² - 30x)
-----------------------------
+ 18x + 9
- (18x + 54)
----------------------
-45
2x² + 10x + 18 R: -45/x + 3 is your answer R: = remainder
hope this helps
First you find the mean of your data set-add all of the numbers and divide by how many numbers you have.=25
Then you find the difference of your mean and each of the numbers in the data set.(subtract each number from the mean and write that number down)
25-21.5=3.5, 26.6-25=1.6, 25.8-25=.8, 25-23.1=1.9, 25-20.1=4.9, 32.9-25=7.9
Finally, find the mean of the new numbers you got when you subtracted each number from the mean.
3.5+1.6+.8+1.9+4.9+7.9=20.6/6=3.43 MAD
This mean you found is called the MAD or Mean Absolute Deviation. Hope his helps.
I believe the answer is -16. Cause 4 - 60 + 40 = -60 + 44 = -16. I'm sorry this is a week late.
Answer:
Mean
Step-by-step explanation:
Mode:
Before adding 97 = 38
After adding 97 = 38
Mean:
Before adding 97 = 513/9 = 57
After adding 97 = 610/10 = 61
Median:
38, 38 , 38, 43, 54, 56, 70, 79, 97
Before adding 97 = 54
38, 38 , 38, 43, 54, 56, 70, 79, 97, 97
After adding 97 = 54 +56/2 = 110/2 = 55
X^2+10x+29=0
Quadratic Formula:
−b±√b^2−4(ac)/2a
Substitute the values :
a=1, b=−10, and c=29
into the quadratic formula and solve for
x.
10±√(−10)^2−4•(1•29)/ 2•1
Simplify.
Answer: x=5±2i
