The average (mean) absolute deviation of a data set is the average of the absolute deviations from a central point.

so we need to calculate the mean of this data set firstly:::
the mean of (7,10,19,14,3) = \frac{7+10+19+14+3}{5} =10.6

then we will calculate how far each record is from this mean:::
7-10.6 = - 3.6
10-10.6 = - 0.6
19-10.6 = 8.4
14-10.6 = 3.4
3-10.6 = - 7.6


BUT as it requires the ABSOLUTE mean deviation, we will take the absolute values of the previous results

3.6  &    0.6  &    8.4  &    3.4  &    7.6

Adding them together and divide by the records number (5)::

ABSOLUTE mean deviation = \frac{3.6+0.6+8.4+3.4+7.6}{5} =4.72


Done!!!



I hope you got the idea

What is the slope of the line through points (0,6) and (5,-4)
anastassius [24]
The slope between the points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1)

(0,6) and (5,-4)
x1=0
y1=6
x2=5
y2=-4

slope=(-4-6)/(5-0)=-10/5=-2

A number d minus is less than -1
katrin [286]

\boxed{d-4

<h2>Explanation:</h2>

Hello! Recall you need to write complete questions in order to find exact answers. So in this problem I'll assume the question is:

<em>A number d minus 4 is less than -1</em>

<em />

So it is easy to know that we need to write an inequality here because of the words "less than", which implies that we must use the symbol <. So let's solve this step by step.

Step 1. A number d minus 4.

This statement includes the word "minus", so we need to use the symbol (-). Therefore:

d-4

Step 2. A number d minus 4 is less than

As we said above, here we need to use the symbol (<). So:

d-4

Step 3. A number d minus 4 is less than -1

Finally, we get:

d-4

Kate Alexander worked 40 hours last week. Her pay rate is $8.50 per hour. Assuming 7.65% social security withholding, how much s
Andrej [43]
40 x 8.50 = 340
340  x  .0765 = 26.01

So the employer should withhold $26.01 from her check for social security.

Girls 2x

Total 109

2x+x=109

3x=109/:3

X=36,3333

Boys x =36$ 33c

Girls 2x= 72,666= 72$ 67c

Irma needs to rent a car for a business trip from phoenix to san jose (720 miles one way). she will drive round trip and will be
marusya05 [52]
To find the number of miles Erma can drive, you will write and equation and solve it to find the amount of miles that can be driven on $600 over the 1600 miles that are allowed.

Daily rate  + cost per mile over 1600 = total cost
(65 x 8) + 0.24m = 600
520 + 0.24m = 600
-520             -520
<u>0.24m </u>= <u>80</u>
0.24       0.24
m = 333.33... miles

The maximum number of whole miles she can drive would be 1933 miles (1600 + 333).
