Answer:
6 i think double check though
Step-by-step explanation:
You should choose c because parallel lines have the same slope
Answer:
No solutions.
Step-by-step explanation:
3x+11=3x-11
11=-11. (Subtract 3x from both sides)
No Solutions.
Given:
The speed, s, is measured in miles per hour, and distance, y, is measured in yards.
The regression line is given by
...(i)
To find:
The slope and y-intercept of the regression line.
Solution:
The general form of linear regression line is
...(ii)
where x is variable. In the given equation the variable is denoted by s.
On comparing (i) and (ii), we get
![a=4.17, b=52.45](https://tex.z-dn.net/?f=a%3D4.17%2C%20b%3D52.45)
It means slope is 52.45 and y-intercept is 4.17.
The slope, b = 52.45, indicates that the distance increases by 52.45 yards for every one mile per hour of speed.
The y-intercept, a = 4.17, is the distance estimated by this model if the speed is zero miles per hour.
Therefore, the correct option is A.
