The median is the middle term in a group of data when arranged from least to most. Let's arrange the numbers from lowest to highest.
19, 20, 24, 28, 31, 37, 39, 43, 47
The middle term is 31. Thus, the media of this data is 31.
The answer should be X= 3.60m
The data points that fall within the mean absolute deviation are 2.9 and 3.1.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation is the mean average distance between every data point and the mean of the data set.
From the information given:
- Mean of the data set = 5.3
- Mean absolute deviation = 2
The mean absolute deviation is:
= (|5.3 - 2|)/1
= 3.3
Thus, the data points that fall within the mean absolute deviation are 2.9 and 3.1.

Answer:
-0.3
Step-by-step explanation:
One way is facing the positive direction and the other way is the negative direction. C is on the negative side and you just needed to count where the black dot was starting from 0 and it got you to -0.3.
Hope this helps and have a great day! =D
