Question

DIA and a randomly selected 25% of the seventh grade students and ask her favorite ice cream flavor of the students surveyed 60 students chose vanilla as their favorite based on the data what is the most reasonable prediction of the number of seventh graders in her

Answer 1

240 students

Explanation:

The question says that DIA and a randomly selected 25% of the seventh grade students and ask her favorite ice cream flavor of the students surveyed 60 students chose vanilla as their favorite based on the data what is the most reasonable prediction of the number of seventh graders in her.

Let's assume that there are X students in the class(since we weren't given a definite number of student in the class we assign one for ourselves)

25% of the students were randomly selected.

That is 25/100 × X of the students were selected and of this percentage of students picked,60 of them like vanilla.

From here we weren't given any much data to work with and we just told to kind of predict the number of students in that class.

With that in mind, let's now assume that the 25% of students picked all like vanilla which also means that the random selection of the students were actually 60.

Then to find the number of students in the class, we have:

25/100 × X = 60

X/4 = 60

X = 240 students

Answer 2

236 students.

Explanation:

It means that 60 students represents 25% of the seventh grade class plus DIA, which is another student.

From the above we can infer that 59 students are 25% of the class.

Therefore the total number of students, we check it by a rule of three, like this:

total students % of students

59 0.25

X 1

Therefore X is the same:

X = 1 * 59 / 0.25 = 236

Which means that in the seventh grade class there are a total of 236 students.
