Multiple 2 by -5
ANSWER =-10xy^2
To Solve MAD or the mean absolute deviation what you need to do is get the Mean so lets say you have the numbers 20,35,18,34,60,82,10, and 29 add them up to get 228. next divide by the amount of numbers 228/8 = 36 now to get the mean absolute deviation get the difference of each number, but some will be negative so we will turn them to positive Like so.
20-36=-16 turn to positive 16
36-35=1
36-18=18
36-34=2
60-34=24
82-34=46
36-10=26
and 36-29=7
you add up these numbers to get 140 then divide them by the numbers 140/8=17.5
<span>so 17.5 is your mean absolute deviation.</span>
Answer:
4x²
Step-by-step explanation:
Your equation is 4x² - 6x² + 7x² - 20x² + 19x².
Since they all have the same variable, simply combine them all to find your answer.
4x² - 6x² + 7x² - 20x² + 19x²
-2x² + 7x² - 20x² + 19x²
5x² - 20x² + 19x²
-15x² + 19x²
4x²
Answer:
4
Step-by-step explanation:
5 times 12 plus unknown is 80 so 80 divided by 5 is the sum of 12 + unknown number. So 80 divided by 5 is 16. 12 plus unknown is 16 so the unknown number is 4.
