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
for the table its 30 * the hours +20 for example 30(1)+20=50 or 30(4)+20=140. the total cost is 30 times the hours plus 20.
Answer:
-1/6
Step-by-step explanation:
You turn the problem into 1/2 x -1/3. Doing the equation you get -1/6
You distribute the two in the parenthesis and add both the x and then the 18 and 2 which gives you 20 ;X=20
