The MAD of the given data set is 3.3.

The average absolute distance between each data value and the mean of a data set is measured as the mean absolute deviation (MAD). MAD is a metric or statistic that, like standard deviation, evaluates the spread or variance in your data. We assess the absolute distance between each data point and the mean in order to compute MAD. After that, averaging such distances. The MAD equation is as follows:

[tex]\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|[/tex]

m(X) = average value of the data set

n = number of data values

x_i = data values in the set

Given a data set of  yearly rainfall for a 9-year period in inches:

29, 24, 19, 21, 23, 27, 26, 29, 18

The Mean of the given data is 24. The following table will calculate the Absolute deviation.

Data Value Deviation from mean Absolute Value of Deviation

29                            29-25 = 4           |4| = 4

  24                    24-25 = -1    |-1| = 1

  19                            19-24 = -5           |-5| = 5

   21                    21-24= -3     |-3| = 3

   23                         23-24= -1           |-1| = 1

   27                    27-24 = 3    |3| = 3

   26                     26-24 = 2          |2| = 2

   29                   29-25 = 4           |4| = 4

   18                     18-24 = -6           |-6| = 6

Total of Absolute Deviations: 24

For MAD = 24/9 = 3.222

Therefore,  the MAD for this set of data in inches is 3.222≅ 3.3 inches.

Answer:

x = 10, y = 0

Step-by-step explanation:

x + y = 10 ---> x = 10 - y

3x + 2y = 30

3 (10 - y) + 2y = 30

30 - 3y + 2y = 30

y = 0

x + 0 = 10

x = 10

c ≈ 5.83095189485

Step-by-step explanation:

We can use the Pythagorean Theorem [tex](a^{2} +b^{2} =c^{2} )[/tex] for these kinds of problems.

So, pretend that line is the hypotenuse of a right triangle. One side would be

3 units long and another would be 5 units long. Let's plug that into the theorem.

3² + 5² = c²

Simplify.

9 + 25 = c²

Add.

34 = c²

And now square root both sides.

√34 = c

c ≈ 5.83095189485

Answer:

x = 14

Step-by-step explanation:

First put it into slope intercept form

20 = 2x - 8

Move the variable to the left hand side and change its symbol

-2x + 20 = -8

Move the constant to the right hand side and change its symbol

-2x = -8 - 20

Calculate the difference

-2x = -28

Divide both sides of the equation by -2

x = 14

Solution

X = 14

Answer:

a = -1

Step-by-step explanation:

4a3a = (4+3)2-5 = 7a

12a = 14a - 5 = 7a

12a = 14a - 5 - 7a = 0

12a -14a + 5 + 7a = 0

(12 - 14 +7)a + 5 = 0

5a + 5 = 0

5a = -5

a = -1

Answer:

29.87%

Step-by-step explanation:

£9.75 \ 12 = £0.77

This is what he pays for each bottle

He makes £0.23 on each bottle sold

0.23/0.77 x 100 = 29.87

This is the percentage profit.

You can also validate the answer by calculating 29.87% of £0.77 and then add it to the £0.77 and you will see that you get £1
