We know that
The MAD is <span>the mean absolute deviation of the data
step 1
</span><span>To find the mean absolute deviation of the data, start by finding the mean of the data set.
</span><span>Find the sum of the data values, and divide the sum by the number of data values
</span>sum of the data values=[130+150+190+100+175+120+165+140+180+190]
sum of the data values=1540
number of data=10
Mean=1540/10-----> 154
step 2
<span>Find the absolute value of the difference between each data value and the mean: |data value – mean|.
</span> |130 – 154|=24
|150 – 154|=4
|190 – 154|=44
|100 – 154|=54
|175 – 154|=21
|120 – 154|=34
|165 – 154|=11
|140 – 154|=14
|180 – 154|=26
|190 – 154|=44
step 3
<span>Find the sum of the absolute values of the differences.
</span>=[24+4+44+54+21+34+11+14+26+44]------> 276
step 4
<span>Divide the sum of the absolute values of the differences by the number of data values.
</span>276/10-----> 27.6
the answer is
27.6
Answer:
Because +- or - + = -
Step-by-step explanation:
-a + b = - c
a + - b = - c
-a × b = - c
a × - b = -c
Extra references:
-ve ×/+ -ve = +ve
+ve ×/+ -ve = - ve
-ve ×/+ +ve = - ve
+ve ×/+ +ve = +ve
Hope these could solve your problem.

Answer:
(d) one output for every input
Step-by-step explanation:
A function is 1-to-1 if its graph passes the horizontal line test: a horizontal line may intersect the graph in only one place.
Your answer is correct... 
, so
Then distributing 
to both terms on the right gives
Answer:
7) 2((7x12) + (7x2) + (12x2)
2(84 + 14 + 24)
2(122)
<u>244</u>
8) 2((13x4) + (4x6) + (13x6))
2(52 + 24 + 78)
2(154)
<u>308</u>
9) 2((4x15) + (4x8) + (15x8))
2(60 + 32 + 120)
2(212)
<u>424</u>
