Answer:
10
Step-by-step explanation:
Begin with writing down your problem. For example, you want to divide 1284 by 14.
Decide on which of the numbers is the dividend, and which is the divisor. The dividend is the number that the operation is performed on - in this case, 1284. The divisor is the number that actually "does the work" - in this case, 14.
Perform the division - you can use any calculator you want. You will get a result that most probably is not an integer - in this example, 91.7142857.
Round this number down. In our example, you will get 92.
Multiply the number you obtained in the previous step by the divisor. In our case, 92 * 14 = 1294.
Subtract the number from the previous step from your dividend to get the remainder. 1284 - 1294 = 10.
Answer:
![\bar X = \frac{0.4+0.2+0.4+0.6}{4}= 0.4](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B0.4%2B0.2%2B0.4%2B0.6%7D%7B4%7D%3D%200.4)
Now we can calculate the absolute deviations from the mean for each value:
|0.4-0.4|=0
|0.2-0.4|=0.2
|0.4-0.4|=0
|0.6-0.4|=0.2
And adding these 4 values and dividing by 4we got the MAD on this case:
![MAD = \frac{0+ 0.2+0 +0.2}{4}=0.1](https://tex.z-dn.net/?f=MAD%20%3D%20%5Cfrac%7B0%2B%200.2%2B0%20%2B0.2%7D%7B4%7D%3D0.1)
Step-by-step explanation:
We have the following dataset given:
0.4,0.2,0.4,0.6
In order to calculate the MAD we need to calculate the sample mean first with this formula:
![\bar X = \frac{\sum_{i=1}^n X_i}{n}](https://tex.z-dn.net/?f=%5Cbar%20X%20%3D%20%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D)
Replacing we got:
![\bar X = \frac{0.4+0.2+0.4+0.6}{4}= 0.4](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B0.4%2B0.2%2B0.4%2B0.6%7D%7B4%7D%3D%200.4)
Now we can calculate the absolute deviations from the mean for each value:
|0.4-0.4|=0
|0.2-0.4|=0.2
|0.4-0.4|=0
|0.6-0.4|=0.2
And adding these 4 values and dividing by 4we got the MAD on this case:
![MAD = \frac{0+ 0.2+0 +0.2}{4}=0.1](https://tex.z-dn.net/?f=MAD%20%3D%20%5Cfrac%7B0%2B%200.2%2B0%20%2B0.2%7D%7B4%7D%3D0.1)
