60/100 represents the amount Amyra has.
Let's divide wach side by 10 to get...
6/10
Let's divide each side by 5 to get...
3/5.
That is the answer hope it helps!
Based on the figures above, the numbers of children that attended the park that day is 10,000.
<h3>What is the matrix equation about?</h3>
Fist we have to use the determinant to solve for c and as such:
![\frac{det.\frac{30000}{500000} \frac{1}{20} }{det. \frac{1}{10} \frac{1}{20} }](https://tex.z-dn.net/?f=%5Cfrac%7Bdet.%5Cfrac%7B30000%7D%7B500000%7D%20%20%20%20%5Cfrac%7B1%7D%7B20%7D%20%7D%7Bdet.%20%5Cfrac%7B1%7D%7B10%7D%20%20%5Cfrac%7B1%7D%7B20%7D%20%20%7D)
=![\frac{30000 x 20 - 500000 x 1}{1 x 20 - 1 x 10}](https://tex.z-dn.net/?f=%5Cfrac%7B30000%20x%2020%20-%20500000%20x%201%7D%7B1%20x%2020%20-%201%20x%2010%7D)
= 100000/10
=10,000
Therefore, Based on the figures above, the numbers of children that attended the park that day is 10,000.

Given that the die-cast plane is scaled at 1 inch to 1 foot. This means that for each foot of the actual plane, the toy is 1 inch.
Therefore, the dimensions of the actual plane is given by 1 x 6.5 inches wide by 1 x 8.5 inches long = 6.5 inches wide by 8.5 inches long.
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)
