Answer: try D
Step-by-step explanation:
To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
For the first set:
MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15
For the second set:
MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.
Expand the brackets on the right side so,,
12x + 20 = 6x + 24
Collect like terms and place the x’s on one side and the numbers on one side ,,
6x = 4
Divide both sides by six to get x alone,,
X= 6/4
X = 1.5
