Answer:
MAD = 0
Step-by-step explanation:
When I calculated this by hand I got 0. To find the MAD:
1. You first need to find the mean of the numbers.
4 + 5 + 8 + 8 + 10 = 35
35/5 = 7
the mean value = 7
2. Then you must find the absolute value of the difference between each data value and the mean: |data value – mean|
(4 - 7) = -3
(5 - 7) = -2
(8 - 7) = 1
(8 - 7) = 1
(10 - 7) = 3
3. Add the difference values up
(-3) + (-2) + 1 + 1 +3 = 0
4. Divide the sum of the absolute values of the differences by the number of data values.
0/5 = 0
Answer:
x = 7
Step-by-step explanation:
Start by solving for
which is a common expression for both equations. Then in the first equation:
![3\,x5\,(y+x)^2=16\\3x-16=5\,(y+x)^2\\(y+x)^2=\frac{3\,x-16}{5}](https://tex.z-dn.net/?f=3%5C%2Cx5%5C%2C%28y%2Bx%29%5E2%3D16%5C%5C3x-16%3D5%5C%2C%28y%2Bx%29%5E2%5C%5C%28y%2Bx%29%5E2%3D%5Cfrac%7B3%5C%2Cx-16%7D%7B5%7D)
and in the second equation:
![4\,x+2\,(y+x)^2=30\\2\,(y+x)^2=30-4\,x\\(y+x)^2=15-2\,x](https://tex.z-dn.net/?f=4%5C%2Cx%2B2%5C%2C%28y%2Bx%29%5E2%3D30%5C%5C2%5C%2C%28y%2Bx%29%5E2%3D30-4%5C%2Cx%5C%5C%28y%2Bx%29%5E2%3D15-2%5C%2Cx)
Now we make the two
expressions equal so we get:
![\frac{3\,x-16}{5} =15-2\,x\\3\,x-16=75-10\,x\\13\,x=75+16\\13\,x=91\\x=7](https://tex.z-dn.net/?f=%5Cfrac%7B3%5C%2Cx-16%7D%7B5%7D%20%3D15-2%5C%2Cx%5C%5C3%5C%2Cx-16%3D75-10%5C%2Cx%5C%5C13%5C%2Cx%3D75%2B16%5C%5C13%5C%2Cx%3D91%5C%5Cx%3D7)
