Answer:
<h2>B. 2 points </h2>(Approximately)
Step-by-step explanation:
The mean absolute deviation (MAD) is defined as
Where is the means and
is the total number of elements.
First, we need to find the mean:
Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.
18 - 14 = |4|
12 - 14 = |-2|
15 - 14 = |-1|
10 - 14 = |-4|
13 - 14 = |-1|
20 - 14 = |6|
16 - 14 = |2|
12 - 14 = |-2|
18 - 14 = |4|
6 - 14 = |-8|
Now, we sum all terms and divide them by the total number of elements, which are 14.
Therefore, the absolute deviation is about 2 points. The right answer is B.
Answer: See the diagram below.
The graph consists of a closed circle at -2, an open circle at 3, and shading in between.
===============================================
Work Shown:
Notes:
In the 2nd step, I subtracted 9 from all sides to undo the "plus 9"
In the 4th step, I divided all sides by 4 to undo the multiplication.
-------------------
To graph this, you'll have a closed circle at -2 and an open circle at 3. The shaded region is in between. The open circle means "do not include this endpoint".
See the diagram below.
