Answer:
1. See attached for dot plot
2. 12
3. longest ski trail = [tex]3\frac14[/tex]
shortest ski trail = [tex]1\frac38[/tex]
⇒ difference = [tex]3\frac14-1\frac38=1\frac78[/tex] miles
4. There are 3 trail that are [tex]2\frac78[/tex] miles long.
⇒ total length = [tex]3 \times 2\frac78=8\frac58[/tex] miles
5. Sum of shortest trail and longest trail = [tex]3\frac14+1\frac38=4\frac58[/tex] miles
6. 3 times the shortest trail = [tex]3 \times 1\frac38=4\frac18[/tex] miles
longest trail = [tex]3\frac14[/tex] miles
Therefore, Eli is correct as [tex]3\frac14<4\frac18[/tex]
