30. Each of the people in a survey chose one of the four countries shown as the country that person wanted to visit. The incomplete table shows the results of the survey. What fraction of the people surveyed chose Australia?

Answer: C

Explanation:

The fraction of the people surveyed who chose Australia is 20-Mar.

In the survey, the results indicate that a total of 20 out of a total of 60 people surveyed chose Australia, which simplifies to the fraction 20-Mar.

A) 15-Jan

This option suggests that 15 individuals chose Australia, which is incorrect based on the survey data. The number 15 does not represent the correct amount of respondents indicating a preference for Australia.

B) 05-Jan

Choosing 5-Jan implies that only 5 people selected Australia as their desired destination. This is incorrect, as the survey results clearly reflect a higher number of respondents.

C) 20-Mar

This option accurately represents the fraction of individuals who chose Australia. With 20 respondents out of a total of 60, this fraction correctly simplifies to 20-Mar, making it the right choice.

D) 17/20

The fraction 17/20 indicates that 17 out of 20 people chose Australia, which is incorrect since the total number of respondents is 60, not 20. This misrepresents the data presented in the survey.

Conclusion

The correct answer, 20-Mar, directly corresponds to the survey results, confirming that 20 individuals selected Australia. Other options either misrepresent the number of respondents or do not fit within the context of the total survey data, making them incorrect. Thus, 20-Mar is the definitive answer reflecting the fraction of people who chose Australia.
