Answer:
They are adjacent
Step-by-step explanation:
Only 3(a−b) and 3a−3b are equivalent
Further explanation:
We have to evaluate each expression to evaluate if the expressions are equivalent or not.
So,
<u>For 3(a−b)</u>
![3(a-b)\\Distributing\ 3\ in\ bracket\\3.a-3.b\\=3a-3b](https://tex.z-dn.net/?f=3%28a-b%29%5C%5CDistributing%5C%203%5C%20in%5C%20bracket%5C%5C3.a-3.b%5C%5C%3D3a-3b)
As we can see that 3(a-b) results in 3a-3b so these are equivalent
<u>For 2a(2+b)</u>
![2a(2+b)\\Distributing\ 2a\\2a.2+2a.b\\=4a+2ab](https://tex.z-dn.net/?f=2a%282%2Bb%29%5C%5CDistributing%5C%202a%5C%5C2a.2%2B2a.b%5C%5C%3D4a%2B2ab)
As we can see that 2a(2+b) doesn't result in 4ab so these are not equivalent
Hence,
Only 3(a−b) and 3a−3b are equivalent

Answer:
Mean absolute deviation is the average of the absolute deviations from the mean. It is a measure of variability, which gives us an idea about the spread of data points from mean. Therefore, the small MAD means the data points are less deviated from mean. And the large MAD means the data points are more deviated from mean.
Hence, smaller the MAD lesser the variation in data.
