36 students signed up to volunteer for a race two or three equal groups of students and each group had a different task how many students were in each group

I two groups are formed: 18 students

If 3 groups are formed: 12 students

Step-by-step explanation:

We will answer this problem based on two occurrences:

1. The students chose to form only two groups:

If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.

2. The students chose to form three groups:

If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
