What is the question. Inform me what it is so i can help
Answer:
![y=\frac{1}{3}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx%2B2)
Step-by-step explanation:
find the slope of the line using ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m=\frac{3-2}{3-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B3-2%7D%7B3-0%7D)
![m=\frac{1}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B3%7D)
slope intercept form is ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
use one of the given points to substitute for
and
.
![y-2=\frac{1}{3}(x-0)](https://tex.z-dn.net/?f=y-2%3D%5Cfrac%7B1%7D%7B3%7D%28x-0%29)
simplify
![y-2=\frac{1}{3} x](https://tex.z-dn.net/?f=y-2%3D%5Cfrac%7B1%7D%7B3%7D%20x)
add 2 to both sides
![y=\frac{1}{3}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7Dx%2B2)
The mean is also known as the average. For this problem, we want to find out the average distance that the guesses were from the true temperature. To do this, we need to add up all of the values and divide them by the number of values we have.
Person A:
-3 + -1 + 0 + 2 = -2
4 values
Person B:
4 + -4 + 2 + -3 = -1
4 values
Person C:
8 + -2 + 5 + 1 = 12
4 values
Totals:
-2 + -1 + 12 = 9
4 + 4 + 4 = 12 values
Find average:
9/12 = 0.75
The mean value in Fatima's results is 0.75.
Hope this helps!! :)
