I assume that the numbers are: 4,4,6,1,5,2,6
If so, then the MAD is 1.43
To find the MAD, you first find the mean of the list. It is 4.
Then find the absolute difference of each number from the mean.
Those values are: 0,0,2,3,1,2,2
Now find the mean of those numbers and you have about: 1.43
You look at the hundreths place (4) and if it is 5 or more you round the tenths place up. so the number is rounded to 9.2
The answer to 6 2/3 divide by 9 2/3 should equal to 20/29.
We know that y=MX+c
here m=1 and c=-1
The answer is C. 55
You get your answer by adding together the degrees of the angles you know 55+70
That equals 125 degrees and subtract that from 180 degrees
180-125= 55
