The mean absolute deviation is 10.52.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It is a measure of variation of a data set.
MAD =1/n ∑ l x - m(x) l
Where:
n = total numbers in the data set
x = number
m(x) - median
The first step is to determine the mean of the data set: (42 + 31 + 1 + 1 + 2 4+ 5 + 6 + 7 + 3) / 10 = 10.2
Find the absolute value of the difference between the number and the mean. Add the result | (42 - 10.2) + (31 - 10.2) + (1 _ 10.2) + (1 - 10.2) + (2 - 10.2) + (4 - 10.2) + (5 - 10.2) + (6 - 10.2) + (7 - 10.2) + (3 - 10.2) = 105.2
Divide the sum by the total number in the dataset = 105.2 / 10 = 10.52

Hey there,
#1 is D: 18 men and 30 women. The equation is: 12*m=48
#2 is B: Kathy drove 9 hours and Brain drove 3 hours. The equation is: 65m+55m/12=750
#3 is C: $0.86. The equation is: 2b+1h+1b+2h=8.52
#4 is B : 25 pizzas and 80 sodas. The equation is: 3*4p+5=260
