To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2 The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2 2=0 away from 2 4=2 away from 2
You should get: 1,1,0,0,0,2 Next, you have to find the mean of the new set of numbers. 1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3
Answer:
2
Step-by-step explanation:
To calculate the value of the given rational expression (2x + 6) / (4x - 8), it is a good idea to simplify it first.
To simplify this expression, we can take the common out of both, the numerator and the denominator, as shown:
From the term 2x + 6, we can take out 2 as the common and from 4x-8, we can take 4 as common so the terms will become;
2 (x + 3) / 4 (x - 2)
2 from the numerator and 4 from the denominator will get cancelled and we will get x+3 / 2(x-2)
so we will solve for x-2 = 0 to get x = 2 which is the excluded value.
