please help me to answer this question. justify your answer please
a student council has five seniors, four juniors, three sophomores, and two freshmen as members. in how many ways can a four member council committee be formed that includes one member of each class?
you can pick 1 senior in 5 ways, 1 junior in 4 ways, 1 sophomore in 3 ways and i freshman in 2 ways.
in all you can make these selections i 5 * 4 * 3 * 2 ways = 120 ways.
 
please note: selecting a committee is a "combination" problem, not a "permutation".
juniors. college students are classified the same as high school students. 1st year are freshman. 2nd year are sophomores. 3rd year are juniors, and 4th year are seniors. hi katie,

there a certainly mixed reviews on the worth of a conclusion. i personally recommend that my students write one that is 4-5 sentences long. however, i encourage them to only spend 3-4 minutes writing one. in general, you want to spend as much time as you can writing your body paragraphs … dear student,

regards One difficulty is that it's far from clear what the ideal dropout rate should be. Probably not zero, for two reasons:

 1. Even the best students sometimes find that their interests change over time, in ways nobody could have predicted. Dropping out may become a quite sensible choice, in which case it's harmful for the university to discourage it.
2. It's reasonable for a university to give someone a chance even if it's not certain that they will succeed. The only way to get a really low drop-out rate is to admit just the applicants that are obviously destined for success. The top few schools can get away with this, but if everyone tried it, then many talented candidates would be shut out from graduate school.

 So some attrition is OK, and some is bad but may be a necessary consequence of policies that are on the whole good. The question then becomes how you distinguish these kinds from needless and damaging attrition, and then how you minimize that kind.

 Advisors play a key role here, because some are much better than others at being supportive or motivational. However, at least in mathematics, most advisors don't supervise very many students, so the numbers often aren't large enough to see patterns clearly.

 I'm sure people have studied this problem, and perhaps identified best practices for addressing it. However, in my experience any studies or solutions are not especially influential (at least in the few math departments I've been in). Most discussions are at the stage of trying to figure out whether there is a real problem and if so why, rather than what to do about it. There could be a variety of leaderboards. Like one of top points overall, and another for the most points gained in the previous 4 weeks or something. I may never top to overall leaderboard, but I have a chance of getting on a monthly leaderboard. dear student,

the answers are:

what she could do for him
that he needed a room, preferably on the first floor
to let her see if the room was available

regards hi,

open up the guild screen by hitting the "o" key followed by selecting the guild tab. the guild must already be created and you must be a member of the guild. you will now see a guild listing with several different options.

below the guild player listing you will find another area with a bunch of various buttons.

new guild? 
group invite - select a player on the list, then hit this button to invite them into your party. http://www.usfine.com
guild control - this will launch a control window pane where you can edit the ranks of the guild and set up permissions for each rank. this will be explained in detail further down the page. 
add member - press this button then enter the name of the player you wish to invite to the guild. once they accept your invitation they will be added to the guild. if they do not accept you will have to invite again.

at the very bottom of the guild tab you will see:

promote - select a player on the list then hit "promote" to set their rank to a higher rank in the guild. a message will be sent to the entire guild that this player's rank has changed, so be careful when using it. 
demote - select a player on the list and hit "demote" to demote that player one rank in the guild. 
remove - select a player on the list and hit "remove" to kick them out of the guild. it is given in the question that,
from class a students who passed in first class = = 

also,
from class b students who passed in first class = = 

therefore, from above results it is clear that in the both the classes equal fraction of students passed in the first class the voting & ratings system is very different.

you get ratings usually from the other answerers on that question, & votes come from people who go to the vote section to vote on multiple questions for some extra points.

there are also answerers who vote for themselves, & yes, some of them do cheat & use email to tell their friends which answers to vote on. i've seen it done many times. in order to have the election process more democratic there are few pre-requisites like:a. one vote, one value: to choose/elect the representative everyone must have one note with equal value. this is to avoid any type of conflicting situation.b. regular election: there should be regular elections in every democratic country so that people have their choice at regular intervals.c. free and fair election: in order to ensure a fair chance to the people there should be a free and fair election in every democratic country.d. political competition: in order to have democratic election parties, candidates should be free to contest elections and should offer some real choice to the voters.
