First we find mean.
Mean is 10
Find sum of data set.
7+8+8+9+10+10+11+11+12+14=100
Divide the sum by the number of data values: 100/10=10
|7-10|=|-3|=3
We do this for all number. We subtract the data values by mean. We get:
3+2+2+1+0+0+1+1+2+4=16
16:10=1.6
MAD IS 1.6

Help with this please question 3
MrRissso [65]
3a. Jackson's gross pay for 40 hours is
  (40 h)×($12.20/h) = $488.00

3b. An equation for Jackson's pay could be
  372.10 = h×12.20
This can be solved for h by dividing by 12.20
  372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.

3c. The total of hours shown is
  (8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
  30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.


_____
Of course, you know the decimal - fraction conversions:
  1/4 = 0.25
  1/2 = 0.50
  3/4 = 0.75

What is the value of x
liubo4ka [24]

Answer:

x = 73°

Step-by-step explanation:

a whole circle = 360°

so x + 50° + 91° + 2x = 360°

x+ 2x = 360°- 91° - 50°

3x = 219°

x = 219° ÷ 3

x = 73°
