Question

In a survey, 250 adults and children were asked whether they know how to

swim. The survey data are shown in the relative frequency table.
What percentage of the people surveyed are adults?

Answer 1

The answer is 40%

Explanation:

You first multiply the amount of people surveyed by the decimals shown...250×0.34=85 250×0.06=15 Add them together 85+15=100

Next you divide your answer(100) by 250 which will give you 0.4

Finally, multiply 0.4 by 100 to make it a percent

Your final answer will be 40.
