If 1km is equal to 0.6mi then 5km is equal to 3mi
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)
I can’t see the question (picture is blurry)
Answer:
(-1,-5)
Step-by-step explanation:
first isolate y so it is in slope intercept formula:
8x-3y=9
Subtract 8x from both sides
8x - 8x - 3y= 9 - 8x
-3y = 9 - 8x
Now divide both sides by -3 to isolate y
-3/-3y = 9/(-3) - 8x/(-3)
y = -3 + 8/3x
y = 8/3x - 3
Slope: 8/3
Hope it helps :)
