Question 5<>0/4 pts 2Out of 230 racers who started the marathon, 209 completed the race, 17 gave up, and 4 weredisqualified. What percentage did not complete the marathon? Round your answer to the nearesttenth of a percent.C

Answer 1

It is given that 230 racers started the race, 209 completed it, 17 gave up, and 4 were disqualified.

It is required to find the percentage of the racers that did not complete the race.

To do this, find the fraction of racers who did not complete the race and multiply by 100%.

Since 17 gave up and 4 were disqualified, it follows that the number of racers who gave up is:

`17+4=21`

The total number of racers who started is 230.

Hence, the fraction of racers who did not complete it is:

`(21)/(230)`

Multiply the fraction by 100% to find the required percentage:

`(21)/(230)*100\%=(210)/(23)\%\approx9.1\%`The answer is about 9.1%.
