Question

#1: exercise set 10-2 #34

#2: this is a good opportunity to think about what weve learned in this class.

using your own words, post one problem from any of your aleks homework assignments that was challenging for you. this problem can come from your week 1, 2, 3, 4 or 5 homework assignment. remember that you can go back to any homework assignment and bring up your score before the end of the session.

why was it difficult? what did you try (even if your answer is incorrect)? if you figured out the solution, explain how you figured it out. what course resource (video, text, aleks tools, communication with your instructor, etc.) was most helpful.

out of a group of eight students serving on the student government association, how many different ways can a president, a vice president, and a treasurer be selected?

after you post, please look for your instructors feedback.
you may reply with revisions through the end of the week.

Explanation:

Identify the problem type

This is a counting problem where we select distinct roles from a group.

Determine if order matters

Since the roles (president, vice president, treasurer) are distinct, order matters.

Apply the permutation formula

Using permutations of \(n\) items taken \(r\) at a time:

$$ P(n, r) = \frac{n!}{(n-r)!} $$

For \(n = 8\) and \(r = 3\):

$$ P(8, 3) = \frac{8!}{(8-3)!} = \frac{8!}{5!} $$

Calculate the final value

Expand and simplify the factorial expression:

$$ 8 \times 7 \times 6 = 336 $$

Answer:

336
