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>
Diagonal DF (and y-axis) is the line of symmetry, so point E is the reflection of point G through DF (or y-axis) and its coordinates are (w,0).
Where is the question? I have no idea what I need to do to help u?
Answer:
Only A
Step-by-step explanation:
Let's remember the definition of a function:
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
In A, each input has exactly one output so it's a function.
But in B, the inputs 4 and 9 have two different outputs, it can't represent a function.
The answer is only A.
