When you find the mean you add all of them together. Then you divide your answer by how many numbers there are that you added. 

So what I did was add 29+30+28+32+29+31+27= 205
then divide 205 by 7 and you get 29.285

<h2>Answer:</h2>

Mean= 29.3

and MAD= 1.5

<h2>Step-by-step explanation:</h2>

The data point is given by:

29, 30, 28, 32, 28, 31, 27

The mean of the data point is the average of the data points i.e. it is the ratio of sum of the data points to the total number of data points.

and Mean absolute deviation i.e. MAD is calculated in following steps:

1)  Calculate the mean.

2) Find the absolute difference of each data points from the mean.

3) find the mean of these absolute difference.

The mean of the data points is:

Mean=\dfrac{29+30+28+32+28+31+27}{7}\\\\\\Mean=\dfrac{205}{7}\\\\\\Mean=29.3

Now,

|29-29.3|=0.3

|30-29.3|=0.7

|28-29.3|=1.3

|32-29.3|=2.7

|28-29.3|=1.3

|31-29.3|=1.7

|27-29.3|=2.3

The mean of these absolute difference i.e. MAD is:

MAD=\dfrac{0.3+0.7+1.3+2.7+1.3+1.7+2.3}{7}\\\\\\MAD=\dfrac{10.3}{7}\\\\\\MAD=1.4714

which to the nearest tenth is: MAD=1.5

Which expressionis equal to (-7x+5.1y)-(-9x+5.3y)
Furkat [3]

Answer:

The simplified expression for the given expression will be:

c. 2x-0.2y

Step-by-step explanation:

Given expression:

(-7x+5.1y)-(-9x+5.3y)

To simplify the expression.

Solution:

In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.

<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>

So, we have:

⇒ -7x+5.1y+9x-5.3y

Combining like terms

⇒ -7x+9x+5.1y-5.3y

<em>The like terms can be evaluated as</em>

-7x+9x=2x

5.1y-5.3y=-0.2y

Thus, the simplified expression will be:

⇒  2x-0.2y
