The mean of a data sample can be found by adding all the terms in the data sample and dividing the result by the number of terms. In the first case we have the following data sample:

12,8,15,11,9

The mean of this sample is:

\operatorname{mean}=\frac{12+8+15+11+9}{5}=\frac{55}{5}=11

The mean absolute deviation is the sum of the differences between each data value and the mean, divided by the number of data values, the formula is:

MAD=\frac{\sum ^{}_{}\mleft|x_i-\bar{x}\mright|}{n}

Therefore, we must calculate the positive difference between each value and the mean, add them up, and divide the result by the number of data points in the sample. In the case of the first sample we get:

\text{MAD}=\frac{(12-11)+(11-8)+(15-11)+(11-9)}{5}

Solving the operation:

\text{MAD}=\frac{10}{5}=2

If done this way, all the results for each data set must be correct.

The question is asking you to organize the data in line plot form. to do so you must create a number line (which in this case is provided for you) and put X's above the numbers. for example lets say your given the following data :
1, 2 ,2 , 4 , 1 , 3 , 2 , 5 
this is how you would graph it in line plot form 



x .      x
x .      x .           x .         x .          x

_________________________________________
1 . . .   2 .          3 .         4 .          5
  
but in your case not al the numbers listed are on the plot so instead you do this:
x .    x
x .    x .      x .      x .        x
___________________________________
1 .              3 .                5 . 
plot as if the numbers are there. ( as usual spacing is important)

3+2x = 41<br><br> Need help <br> Show work
Sergio039 [100]

Answer:

x=16

Step-by-step explanation:

when solving for a variable, get the variables to one side of the equation and the numbers to the other side.

3+2x=41

*minus 3 from both sides of the equation to get rid of the number on the side of variables of the equation*

2x=38

to get one variable alone, divide the whole equation by 2

x=16
