The scatterplot shows the highway miles per gallon and city miles per gallon for 8 different car models.

based on the scatterplot, what is the best prediction for city mpg if the highway mpg is 40?

a) 20
b) 35
c) 45
d) 50

The best prediction will be B) 35

Step-by-step explanation:

By looking at the scatterplot ,

we can see that it the City MPG vs Highway MPG approximately falls on a straight line.

we can either find the slope of it ( which might be a little out of syllabus ) or we can extend the line connecting the maximum number of points.

When we do so, We get a line as attached in the diagram.

And we extend it.

From the graph attached we find that the value of City MPG falls somewhere in between the lines of 30 and 35 ( though this is just and approximation).

thus the more appropriate answer would be : 35

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
