Answer:
B
Step-by-step explanation:
328= 82 x 4
348/4 = 87
87 - 82 = 5
Answer:
The equation of the least-squares regression line for this plot is approximately ŷ = 3.8 + two thirds times x.

Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: ![Slope=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We are given:
![x_1=2, y_1=8, x_2=7 \ and \ y_2=8](https://tex.z-dn.net/?f=x_1%3D2%2C%20y_1%3D8%2C%20x_2%3D7%20%5C%20and%20%5C%20y_2%3D8)
Finding slope using formula:
![Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5CSlope%3D%5Cfrac%7B8-8%7D%7B7-2%7D%5C%5CSlope%3D%5Cfrac%7B0%7D%7B5%7D%5C%5CSlope%3D0)
So, the slope of line is 0
Answer:
The transitive property of equality
Step-by-step explanation:
The transitive property states if a=b and b=c then a=c. If two things are equal and one of those two things is equal to another thing, then they all must be equal.
