Answer:

4 sophomore girls .

Step-by-step explanation:

If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:

n° boys = n° girls

n° freshmen = n° sophomore

Currently, there are 10 boys and 6 girls, thus 4 girls must join.

Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.

Therefore, 4 sophomore girls must join.

15% of Alina’s workout consisted of cardio exercise. 25% of Dane’s workout consisted of cardio exercise. Which statement must be
Arisa [49]


The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.

To figure this out, first find 15% of 80 and then 25% of 48.

To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)

To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.

So, the final answer is B. They both equal to 12.

Hope it helps :)
