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.
Answer:
Incorrect/No
Step-by-step explanation:
7x2=14
-7x2=-14
<u>Follow the below guidelines:</u>
- A positive number times a positive number is a positive number
- A negative number times a positive number is a negative number
- A positive number times a negative number is a negative number
- A negative number times a negative number is a positive number
Looking at the last one, we see that -2x-7=14, a positive number

9x - 2 = 67
67 + 2 = 69
69 × 9 = 621
621 = x
