In an introductory statistics class there are 4 men and 6 women. An examination is given, and the students are ranked according to their performance. Assume that no two students obtain the same score. (a) How many different rankings are possible?

3628800

Step-by-step explanation:

The class has a total number of 10 students.

4men + 6women = 10 pupils

No two students scored the same score

Therefore, this implies that there would be 10! Scores

10! = 3628800

But if the men ranked amongst themselves and the women too amongst themselves we would have

(6!)(4!) = 17280

answer: this is not a question

step-by-step explanation: this is a answer

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
