Answer 1

will medal (:

Answer 2

The total number of miles walked by the boys is given by:
\[5\times4+9\times5+3\times6+5\times7=(you\ can\ calculate)\ miles\]
Next you need to divide the total number of miles walked by the boys by the total number of boys. This will give the mean number of miles walked by the boys.

Answer 3

118miles

Answer 4

Yes, that is the total distance walked by the boys. Now you need to divide 118 by the total number of boys.

Answer 5

45 / 118 = 45/118

Answer 6

Not really. The total number of people that was asked is 45. However this number is made up of boys and girls. You need to read the graph to find the total number of boys.

Sorry, my bad. I misread the graph. The total number of miles walked by the boys is given by:
\[\large 3\times4+6\times5+9\times6+5\times7=(you\ can\ calculate)\ miles\]
