A company has 25 applicants to interview, and wants to invite 7 of them on the first day, 6 of them on the second day, 5 of them on the third day, 4 of them on the fourth day and 3 of them on the fifth day of a week. In how many ways can the applicants be scheduled? Select one: (257,6,5,4,3) None 25! P(25;7)xP(19;6) ×P(14;5)xP(10;4)×P(7;3) C(25;7)xC(19;6)xC(14;5)xC(10;4)xC(7;3)

Select one:
(257,6,5,4,3)
None
25!

P ( 25 ; 7 ) × P ( 19 ; 6 ) × P ( 14 ; 5 ) × P ( 10 ; 4 ) × P ( 7 ; 3 )

C ( 25 ; 7 ) × C ( 19 ; 6 ) × C ( 14 ; 5 ) × C ( 10 ; 4 ) × C ( 7 ; 3 )

As given that,
There are total 25 applicants.
So first day he can schedule 7 people's Interview in 25P7 ways.
Second day he can schedule 6 people's Interview in 19P6 ways.
And so on...
So option (d) is correct.

I came here since I know this is the best place to ask a question.
I'm a first year student who changed his major to applied mathematics. In middle school I was a garbage math student, but I realized the importance of math in high school when I was introduced to amazing teachers who truly loved what they did. I put myself in tougher classes and eventually got to AP calculus. There was an error in my idea, I never really got a deep understanding of the stuff I was doing and was struggling since I didn't understand the basics and never really did practice problems.
This year I began to start over from scratch from pre-algebra working to pre-calculus. Even though I have already took Calculus.
I'm in a introduction to research class this semester and we are preforming a meta-analysis of some random topic and then presenting at the end of the semester. I'm really enjoying it, and I will definitely apply for more research as I progress through my undergraduate career. (Urge to Compute)
I know I'll probably never win a field's medal, but I'm really intimidated and humbled by the near perfect SAT math scores and Math Olympiad participants.
It's too late for me to have that, but the best quality I have is sticking with the concepts and problems until I can explain them to my dog. (Basically until I understand it)
I'm really sorry for the long post / soft question, I've just been thinking about this since 11th grade but never asked anyone about it.
Basically I'm just wondering if I'm wasting my time, and if there have been mathematicians that were in a similar situation. (Famous or not.)
Again, sorry for the soft question and thank you for taking the time to read this!

i'm seeking out thoughts for a 15-hour mathematical enrichment course in a chinese language high faculty. What (pretty) simple concern would you advocate as a subject for any such course?
historical past/issues:
My students are generally pretty good at math, but many of them have no longer been uncovered to rigorous or summary mathematical reasoning. an amazing topic would be one that could not be impossibly hard for students who have by no means written or study proofs in English.
i have taught this magnificence three times earlier than. (a part of the purpose that i'm posting that is that i have used up all my thoughts!) the primary semester I taught an introductory range theory elegance (which meandered its way toward a proof of quadratic reciprocity, though I think this become in the end too advanced/abstract for some of the students). the second one semester I taught fundamental graph idea and packages (with a focal point on planarity and coloring). The 1/3 semester I taught a class at the Rubik's dice.
the students' math backgrounds are pretty numerous: a number of them take part in contest math competitions, and so are familiar with IMO-fashion techniques, however many aren't. a number of them may additionally realize some calculus, however I cannot assume it. all of them are superb at what in the united states is on occasion termed "pre-calculus": trigonometry, conic sections, systems of linear equations (though, shockingly, no matrices), and the like. They realize what a binomial coefficient is.
So, any ideas? preferably, i'd like to find some thing a bit "sexy" (like the Rubik's cube) -- tries to encourage wide variety theory through cryptography seemed to fall on deaf ears, however being capable of "see" institution idea on the cube became pretty popular.
(Responses specifically welcome from folks who grew up in the percent -- any mathematical subjects you desire were protected within the excessive college curriculum?)
