leila, larry, and cindy are running for 12th grade class offices. they will be named to the positions of president, vice-president, and secretary according to the number of votes each receives. the person with the most votes will be president, the person with the second-highest number of votes will be vice-president, and so on. in how many different ways can the three students form a set of class officers?

In 6 different ways can the three students form a set of class officers.

Step-by-step explanation:

There are 3 people Leila, Larry, and Cindy and 3 positions president, vice-president, and secretary.

We need to find In how many different ways can the three students form a set of class officers.

This problem can be solved using Permutation.

nPr = n!/(n-r)! is the formula.

Here n = 3 and r =3

So, 3P3 = 3!/(3-3)!

3P3 = 3!/1

3P3 = 3*2*1/1

3P3 = 6

So, in 6 different ways can the three students form a set of class officers.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
