Liam and Sarah have each drawn a line on the scatter plot shown below: The graph shows numbers from 0 to 10 on x and y axes at increments of 1. Dots are made at the ordered pairs 1, 7 and 2, 6 and 3, 5.5 and 4, 5.8 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 2.9 and 9, 2.2 and 10, 1.5. A straight line labeled Line A joins the ordered pairs 0, 7.2 and 10.4, 0. A straight line labeled Line B joins the ordered pairs 0, 7.2 and 9.8, 0.
Which line best represents the line of best fit?
Line A, because it shows a positive association
Line A, because it is closest to most data points
Line B, because it is closest to most data points
Line B, because it shows a negative association

Line A, because it is closest to most data points

Step-by-step explanation:

That is your answer because Line A is the closest to most of the data points, while Line B is more farther away. Also, the line of best fit has nothing to do with the positive or negative association.

Line A

Step-by-step explanation:

It is the closest to the data points

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
