Answer:
Julie and her 2 sisters want to buy a new videogame, it costs $20, if their grandmother gives them $3.20 to buy it, how much will each have to pay?
Step-by-step explanation:
When you have a problem like this you just have to thing on a reason to multiply by a fraction and a withdrawal from the total, if you are multiplying by a fraction, that means you are dividing money, so thats why we put julie and her sisters as subjects, and her grandma givin them money is to withdraw from the total amount those $3.20
Answer:
![M.A.D= 4.9](https://tex.z-dn.net/?f=M.A.D%3D%204.9)
Step-by-step explanation:
Given
12.7, 22, 23.5, 24, 11, 22
Required
Determine the M.A.D
Start by calculating the Mean
![Mean = \frac{\sum x}{n}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
In this case, n = 6
So:
![Mean = \frac{12.7 + 22 + 23.5 + 24 + 11 + 22}{6}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B12.7%20%2B%2022%20%2B%2023.5%20%2B%2024%20%2B%2011%20%2B%2022%7D%7B6%7D)
![Mean = \frac{115.2}{6}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B115.2%7D%7B6%7D)
![Mean = 19.2](https://tex.z-dn.net/?f=Mean%20%3D%2019.2)
Subtract the mean from each element
![12.7 - 19.2 = -6.5](https://tex.z-dn.net/?f=12.7%20-%2019.2%20%3D%20-6.5)
![22 - 19.2 = 2.8](https://tex.z-dn.net/?f=22%20-%2019.2%20%3D%202.8)
![23.5 - 19.2 = 4.3](https://tex.z-dn.net/?f=23.5%20-%2019.2%20%3D%204.3)
![24 - 19.2 = 4.8](https://tex.z-dn.net/?f=24%20-%2019.2%20%3D%204.8)
![11 - 19.2 = -8.2](https://tex.z-dn.net/?f=11%20-%2019.2%20%3D%20-8.2)
![22 - 19.2 = 2.8](https://tex.z-dn.net/?f=22%20-%2019.2%20%3D%202.8)
Take absolute value of the results above
![|-6.5| = 6.5](https://tex.z-dn.net/?f=%7C-6.5%7C%20%3D%206.5)
![|2.8| = 2.8](https://tex.z-dn.net/?f=%7C2.8%7C%20%3D%202.8)
![|4.3| = 4.3](https://tex.z-dn.net/?f=%7C4.3%7C%20%3D%204.3)
![|4.8| = 4.8](https://tex.z-dn.net/?f=%7C4.8%7C%20%3D%204.8)
![|-8.2| = 8.2](https://tex.z-dn.net/?f=%7C-8.2%7C%20%3D%208.2)
![|2.8| = 2.8](https://tex.z-dn.net/?f=%7C2.8%7C%20%3D%202.8)
The mean of the above gives the MAD
![M.A.D= \frac{\sum |x - u|}{n}](https://tex.z-dn.net/?f=M.A.D%3D%20%5Cfrac%7B%5Csum%20%7Cx%20-%20u%7C%7D%7Bn%7D)
![M.A.D= \frac{6.5 + 2.8 + 4.3 + 4.8 + 8.2 + 2.8}{6}](https://tex.z-dn.net/?f=M.A.D%3D%20%5Cfrac%7B6.5%20%2B%202.8%20%2B%204.3%20%2B%204.8%20%2B%208.2%20%2B%202.8%7D%7B6%7D)
![M.A.D= \frac{29.4}{6}](https://tex.z-dn.net/?f=M.A.D%3D%20%5Cfrac%7B29.4%7D%7B6%7D)
![M.A.D= 4.9](https://tex.z-dn.net/?f=M.A.D%3D%204.9)
