Answer:

Use 19, and subtract each number. For example, if it is 15, you do 19 - 15, but if it is over 19, like 24, do 24 - 19. Do this to all the numbers and add them up, thats your mad.

Answer:

<em><u>1.6</u></em>

Step-by-step explanation:

The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.

15 is 4 away from 19, for example

So:

19 - 15 = 4

25 - 19 = 6

19 - 13 = 6

19 - 15 = 4

19 - 18 = 1

20 - 19 = 1

22 - 19 = 3

24 - 19 = 5

4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30

30/19 = 1.5789, rounded to 1.6

X²+x=0<br> x³-25x=0<br> x²=4x<br> 4x²-4x=1
-BARSIC- [3]

Answer:

x²+ x = 0

x ( x +1 ) = 0

x = -1

x³-25x=0

x ( x² - 25 ) = 0

x² = 25

x = 5

x²=4x

x² - 4x = 0

x ( x- 4 ) = 0

x = 4

4x²-4x=1

4x²-4x - 1 = 0

4 x² - 2x - 2x - 1 = 0

2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0

2x- 1 ) ² = 0

2x = 1

x = 1/ 2
