Answer:
7/10
Step-by-step explanation:
7/8 = .875
10/12 = .833
12/14 = .857
7/10 = .7
1/2 - .5
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.

Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2p² + 3s
Step 2: Define variables
<em>p</em> = 3
<em>s</em> = 11
Step 3: Replace variables
2(3)² + 3(11)
Step 4: Evaluate
