Answer:
7.83% did not complete the marathon.
Step-by-step explanation:
Out of 230 racers who started the marathon.
212 completed the race, 14 gave up 4 disqualified
Then total racers who could not complete the marathon
= (14+4) = 18
Now percentage of these racers
= [tex]\frac{18}{\text{total racers}}\times 100[/tex]
= [tex]\frac{1800}{230}[/tex]
= 7.826 ≈ 7.83%
7.83% did not complete the marathon.
The percentage that did not complete the marathon is: 7.826%.
Using this formula
Percentage=Did not finish marathon / Started marathon
Where:
Did not finish marathon=14+4=18
Started marathon=230 racers
Let plug in the formula
Percentage=14+4/230
Percentage=18/230
Percentage= 0.07826×100
Percentage=7.826%
Inconclusion the percentage that did not complete the marathon is: 7.826%.
