The triangles are NOT similar.
If they were the ratios of the sides would be the same.
3 / 4 = .75
5 / 6 = .8333333333
6 / 8 = .75
What you would do, is add up on how many people have is Non-Fiction books and Fiction books. Once you have that, subtract it. You should get an answer of 2.
Answer:
mean for a = 60/10 = 6
mad of a = 2
mean for b = 80/10 = 8
mad of b = 2
Step-by-step explanation:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. The mean absolute deviation, MAD, is 2.
\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|
m(X) = average value of the data set
n = number of data values
x_i = data values in the set
mean = average.
