Find the percentile rank
A teacher gives a 20-point test to 10 students. Find the percentile rank
of a score of 12.
18, 15, 12, 6, 8, 2, 3, 5, 20, 10
can you please show me the steps to solving this and don't use any complicated math terms? thanks.
7 of them are less then 12 how exactly do i convert this to a percentage? and where does the 20 points on the test take place in all this? I know nothing when it comes to math accept the simple stuff could u elaborate more for me please and dumb it down?
because it's a prerequisite to my major , you think most people remember the useless math they learn in high school?there is a reason no one remembers it, it's because you don't use it u lose it, no one needs to know this crap. I'm sure solving the problem is extremely simple and takes less then a minute to show, but instead u dance around the answer and choose to say this is not a tutoring service, like seriously? the url to this website is math help forums, that means you help people with there math , no?
It's not useless. It wouldn't have been invented if it was useless.
Obviously you do, if it's needed for your course. That means that you will be using it in your course and therefore must be using it in your chosen field.there is a reason no one remembers it, it's because you don't use it u lose it, no one needs to know this crap.
Yes the problem is extremely simple, and yes, it took me less than a minute to work out. But the idea of this site is to help people to be able to do maths THEMSELVES, not to do the work FOR you. You have been given some very simple instructions. If you don't understand the words, look them up in a dictionary. If you don't know how to do the underlying maths before you can do this problem, google it, or get a tutor who can teach it all to you. This is a site where we help with SPECIFIC problems, which I gave you promptly, clearly and concisely. It's now up to YOU to attempt it.I'm sure solving the problem is extremely simple and takes less then a minute to show, but instead u dance around the answer and choose to say this is not a tutoring service, like seriously? the url to this website is math help forums, that means you help people with there math , no?
the problem with what you just said is a problem that i believe most school systems have. They teach in 1 way and if you don't follow your not going to be good at it. I learn when i see someone do the problem and i duplicate the steps they took to solving it, it's not a matter of just googling words because i understand what the words mean , i just don't understand how i convert 7 and 12 into a percentage, that would give me 2 percentages if I'm not mistaken , which i might just be mistaken. If you just did the problem that would of taken you a minute to do i could of gotten the information i need to perform it my self and thus learn what i needed to learn. also i need it for the class, i will most certainly not use in the real world which is the point I'm getting at , i obviously do need it to pass the class .
