Answer:

Step-by-step explanation:

add all of them up,  Julie,   6 + 12 + 3 + 4 = 25  

there are 25 total students.  now divide each of the number of people that speak that language by the total students

6/25 = .24 = 24%

12/25= .45 = 48%

3/25 = .12 = 12%

4/25 = .16 = 16%

Also, if you want to just check,  see if the percentages add to 100%

Using the relative frequency concept, it is found that the relative frequencies for students speaking each language is:

  • Arabic: 0.24
  • Spanish: 0.48
  • German: 0.12
  • Vietnamese: 0.16

--------------------------------

A relative frequency of a to b is a/b, that is, the number of desired outcomes divided by the number of total outcomes.

--------------------------------

  • 6 + 12 + 3 + 4 = 25 students.
  • 6 speak Arabic, thus, the relative frequency of students speaking Arabic is 6/25 = 0.24.
  • 12 speak Spanish, thus, the relative frequency of students speaking Spanish is 12/25 = 0.48.
  • 3 speak German, thus, the relative frequency of students speaking German is 3/25 = 0.12.
  • 4 speak Vietnamese, thus, the relative frequency of students speaking Vietnamese is 4/25 = 0.16.
