Answer:
D) (0,9.5) and (10,1.5)
Step-by-step explanation:
a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.
Option A makes a short line above the points. if the line is not through the points, it doesn't work
Option B is drawing a positive line (as in it's increasing) and therefore cannot work
Option C draws a line below the points and does not represent the line of best fit for this scatter plot
Answer: I believe that there are 108 crewmembers on the ship.
Step-by-step explanation: Since for every 5 passengers you have 1 crewmember i divided 540 by 5 landing me at the answer 108.
X+20+10x=20+9x
adding like terms
x(10+1)+20=20+9x
11x+20=9x+20
subtracting 9x from both sides
2x+20=20
subtracting 20 from both sides
2x=0
dividing by two for both sides
x=0
