In the data set below, what is the mean absolute deviation?4461526If the answer is a decimal, round it to the nearest tenth.mean
bixtya [17]
I assume that the numbers are: 4,4,6,1,5,2,6
If so, then the MAD is 1.43

To find the MAD, you first find the mean of the list. It is 4.
Then find the absolute difference of each number from the mean.

Those values are: 0,0,2,3,1,2,2
Now find the mean of those numbers and you have about: 1.43

Slope 4.2; y-intercept (0,3.4)
umka2103 [35]

Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.

y=4.2x+3.4

Use this formula➡️y=mx+b

m is slope, b is y-intercept , x and y are the points like (0, 3.4)

You said it's the y-intercept but it's not. it's just a point on the graph

Choose all that apply :)
Veronika [31]

Answer:

1  Multiply the first equation by -1 then add the equations together

3. Multiply the second equation by -1 then add the equations together

4. Multiply the first equation by -2 then add the equations together

5. Multiply the first equation by 2 the second by -1 then add the equations together

Step-by-step explanation:

x+y = 7

2x+y = 5


1  Multiply the first equation by -1 then add the equations together

-x+-y = -7

2x+y = 5

---------------

x    =-2   then solve for y


2.  Multiply the second equation by -1 first equation by -1 then add the equations together

-x+-y = -7

-2x-y = -5

---------------

-3x -2y = -12

Still have both variables


3. Multiply the second equation by -1 then add the equations together

x+y = 7

-2x-y =- 5

----------------------

-x = 2


4. Multiply the first equation by -2 then add the equations together

-2x+-2y = -14

2x+y = 5

--------------

    -y = -9


5. Multiply the first equation by 2 the second by -1 then add the equations together

2x+2y = 14

-2x-y = -5

--------------

y = 9
