Answer:
(Down Below)
Step-by-step explanation:
Plug in the value of x in the left column for all the values in the equation. I will do a couple for you.
Since -4 is the value of x, substitute it into the equation for x.
![y= -4-5=-9](https://tex.z-dn.net/?f=y%3D%20-4-5%3D-9)
-1
![y=-1-5=-6](https://tex.z-dn.net/?f=y%3D-1-5%3D-6)
0
![y=0-5=-5](https://tex.z-dn.net/?f=y%3D0-5%3D-5)
You can do the rest. You got this! Comment if you need more help!
Answer:
Step-by-step explanation:
The 1 choice. The events are independent because P(red) ×P(green)= P(red and green)
Answer:
![y = -x + 115](https://tex.z-dn.net/?f=y%20%3D%20-x%20%2B%20115)
Step-by-step explanation:
Given
See attachment for graph
Required
The equation of best fit
First, we pick two corresponding points on the graph,
We have:
![(x_1,y_1) =(55,60)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%2855%2C60%29)
![(x_2,y_2) =(45,70)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%2845%2C70%29)
Calculate slope (m)
![m = \frac{y_2 -y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-%20x_1%7D)
This gives:
![m = \frac{70 - 60}{45 - 55}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B70%20-%2060%7D%7B45%20-%2055%7D)
![m = \frac{10}{-10}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B10%7D%7B-10%7D)
![m = -1](https://tex.z-dn.net/?f=m%20%3D%20-1)
The equation is the calculated using:
![y = m(x - x_1) + y_1](https://tex.z-dn.net/?f=y%20%3D%20m%28x%20-%20x_1%29%20%2B%20y_1)
This gives
![y = -1(x - 55) + 60](https://tex.z-dn.net/?f=y%20%3D%20-1%28x%20-%2055%29%20%2B%2060)
Open bracket
![y = -x + 55 + 60](https://tex.z-dn.net/?f=y%20%3D%20-x%20%2B%2055%20%2B%2060)
![y = -x + 115](https://tex.z-dn.net/?f=y%20%3D%20-x%20%2B%20115)
