Step-by-step explanation:
Answer:
The Mean Absolute Deviation is 11
Step-by-step explanation:
Given:
325, 310, 289, 288, 285, 285, 285, 280, 280 and 273
Mean = 290
Required:
Calculate the Mean Absolute Deviation
Provided that we have the value of the mean to be 290 from the question; the following steps will calculate the Mean Absolute Deviation
Step 1: Subtract the mean weight from each weight
325 - 290 = 35
310 - 290 = 20
289 - 290 = -1
288 - 290 = -2
285 - 290 = -5
285 - 290 = -5
285 - 290 = -5
280 - 290 = -10
280 - 290 = -10
273 - 290 = -17
Step 2: Calculate the absolute value of the each results above
|35| = 35
|20| = 20
|-1| = 1
|-2| = 2
|-5| = 5
|-5| = 5
|-5| = 5
|-10| = 10
|-10| = 10
|-17| = 17
Step 3: Calculate the mean of the data above
Mean Absolute Value = ![\frac{35 + 20 + 1 + 2 + 5 + 5 + 5 + 10 + 10 + 17}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B35%20%2B%2020%20%2B%201%20%2B%202%20%2B%205%20%2B%205%20%2B%205%20%2B%2010%20%2B%2010%20%2B%2017%7D%7B10%7D)
Mean Absolute Value = ![\frac{110}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B110%7D%7B10%7D)
Mean Absolute Value = 11
Hence, the Mean Absolute Deviation is 11
If both (1,2) and (-3,-3) were reflected across the y-axis, the x coordinate would reverse. (1,2) would become (-1,2), and (-3,-3) would become (3,-3). In this case, the answer would be A.
