First, to solve for the mean absolute deviation, we need the mean of the data set. So for this case, it's (1+1+2+2+2+4)/6 = 2. To get the mean absolut deviation, we'll need the average of the difference between each data and the mean. That is [ (2 - 1) + (2 -1) + (2 - 2) + (2 - 2) + (2 - 2) + (4 - 2) ]/6 = 4/6 = 0.67. From the choices, the closest is 0.7. So the answer must be A<span>.</span>
Step-by-step explanation:
Z=97°
(D&B are across from each other)
Y=43°
(alternating angles)
X=40°
(inside corners of a triangle) (it is always 180°)
=97°+43°+40°
=180°

Answer: y= -4/3 x + 3
Step-by-step explanation: The slope-intercept form is y=mx + b , where m is the slope and b is the y-intercept.

Answer:
Step-by-step explanation:
6x + ( 14x - 5 ) + ( 17 - 3x )
= 17x + 12
- ( 2 - x ) -3 ( 6 + 8x ) -12,
= -23x - 32
( 4x - 9 ) + 8 ( 2x + 3 ) -7x
= 13x +15
