Answer:
Scatter plot one is not a good fit so answer is first picture to the left in a top row( see the pattern). Second plot is a good fit so the answer is the last right picture in a top row( points around x axis).

A random scatter of points in the residual plot indicates that the linear function is a good fit for the given data. A non random residual plot indicates that the chosen function is not a good fit.
The length of segment St is C.16
Answer:
see below
Step-by-step explanation:
1st pic: m>-64
2nd pic: x≤
3rd : x>-1.4, use the 4th arrow for this (not filled in circle starts at -1.4)
4th: z>1.25 use 4th arrow again
5th: p ≥ 4 use the 2nd arrow
Say . . . (13 lbs)/(5/8 lbs/bag) . . . make sure units cancel . . . 13/5*8 = 20.8 bags . . . but get 21 bags just because you can't buy a fraction of a bag.
