Answer:
a. Slope=0.993
Step-by-step explanation:
The linear regression line can be represented as
y=a+bx
Where a is intercept and b is the slope of regression line.
The given regression line is
Highway mpg=7.903+0.993 city mpg.
Here, the intercept is 7.903 and the slope is 0.993.
The numerical value 0.993 of slope depicts that due to unit increase in city mpg the highway mpg increase by 0.993.
9.76 dollars.
1.22 dollars is the cost for each pound.
If you divide by a decimal, you are breaking apart 1 into multiple pieces and so you are trying to find how many of that size piece will fit into 5. For example if you divide by .5 (point five), there are 2 point fives in 1 so there are 10 point fives in 5. The quotient is larger.
I hope you got that...
