Answer:
Their stomach is upset. they eat the grass to calm their stomach. Don't worry it is good if your dog eats grass because that helps the dog's health out. Grass gives them vitamins and nutrients that helps their bowel system. seriously let you dog eat the grass, they will be okay. my four dogs do it as well and they feel better after. hope this helps
The difference between the gas prices in 2013 and 2001 is 3.00
<h3>Graphing tool</h3>
See attachment for the graph of the line of best fit
<h3>The equation</h3>
Start by calculating the slope of the line of best fit using:
![b = \frac{y_2 -y_1}{x_2 -x_1}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D)
From the line of best fit, we have:
![b = \frac{3 -2}{8 -4}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B3%20-2%7D%7B8%20-4%7D)
The regression equation is then represented as:
![\^y = b(\^x - x_1) + y_1](https://tex.z-dn.net/?f=%5C%5Ey%20%3D%20b%28%5C%5Ex%20-%20x_1%29%20%2B%20y_1)
So, we have:
![\^y = \frac 14 (\^x - 4) + 2](https://tex.z-dn.net/?f=%5C%5Ey%20%3D%20%5Cfrac%2014%20%28%5C%5Ex%20-%204%29%20%2B%202)
![\^y = \frac 14\^x - 1 + 2](https://tex.z-dn.net/?f=%5C%5Ey%20%3D%20%5Cfrac%2014%5C%5Ex%20-%201%20%2B%202)
![\^y = \frac 14\^x + 1](https://tex.z-dn.net/?f=%5C%5Ey%20%3D%20%5Cfrac%2014%5C%5Ex%20%2B%201)
So, the linear regression equation is:
![\^y = \frac 14\^x + 1](https://tex.z-dn.net/?f=%5C%5Ey%20%3D%20%5Cfrac%2014%5C%5Ex%20%2B%201)
In 2001, the value of x is 1.
So, we have:
![\^y_1 = \frac 14\times (1) + 1](https://tex.z-dn.net/?f=%5C%5Ey_1%20%3D%20%5Cfrac%2014%5Ctimes%20%281%29%20%2B%201)
![\^y_1 = 1.25 \\](https://tex.z-dn.net/?f=%5C%5Ey_1%20%3D%201.25%20%5C%5C)
In 2013, the value of x is 13.
So, we have:
![\^y_2 = \frac 14\times (13) + 1](https://tex.z-dn.net/?f=%5C%5Ey_2%20%3D%20%5Cfrac%2014%5Ctimes%20%2813%29%20%2B%201)
![\^y_2 = 4.25](https://tex.z-dn.net/?f=%5C%5Ey_2%20%3D%204.25)
So, the difference (d) between the prices is:
![d = 4.25 - 1.25](https://tex.z-dn.net/?f=d%20%3D%204.25%20-%201.25)
![d = 3.00](https://tex.z-dn.net/?f=d%20%3D%203.00)
Hence, the difference between the gas prices in 2013 and 2001 is 3.00
