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.
1. Substitute the function f(x) into x in g(x)
2. Simply your results in 1. now you have (g o f)(x)
3. Now substitute 6 into your results in 2 to get (g o f)(6)
Each drawing they are just adding another row to the right so for the 7th picture, there would be 28 dots. Another explanation is that they are just adding the same number of dots for each number it is. For example, for the 5th image, they added 5 dots to the previous image and so on.
