What is the MAD of this numbers?
Stella [2.4K]
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

Solve 2(9-x) = 3 ( x +16 )
andreyandreev [35.5K]

Answer: x=-6

Step-by-step explanation:

Let's solve your equation step-by-step.

2(9−x)=3(x+16)

Step 1: Simplify both sides of the equation by distribution

2(9-x)=3(x+16)\\(2)(9)+(2)(-x)=(3)(x)+(3)(16)\\18+-2x=3x+48\\-2x+18=3x+48\\

Step 2: Subtract 3x from both sides.

-2x+18-3x=3x+48-3x\\-5x+18=48

Step 3: Subtract 18 from both sides.

-5x+18-18=48-18\\-5x=30

Step 4: Divide both sides by -5.

\frac{-5x}{-5} =\frac{30}{-5} \\x=-6
