Solve this problem please!?

Question

Well, not to be rude or anything, but the Olympics are coming and I have to watch. What I need to do is a complete a math problem.

I'm sure I've done this before, but I forgot how! =[

Here's the problem:

Mean is 17. Data is N, 16,16,18

What I know...

N is a variable.. But I have to figure out what n equals.

Um..It's a crossword thingie, so it's eight letters.

I'm being really really rude, by asking so much, and I 'know' that some people don't 'waste' their time on answering math equations. I mean C'mon!

But all I want you to do is to show me how to do it, (use alternative numbers if you are not comfortable with cheating. I'm not, I'm a straight A student and it better stay that way.

School just started. This is my second math assignment.

Thanks. (i'm not surprised if nobody answers my stupid question, lol..)

Answer 1

(N+16+16+18)/4=17

(N+50)/4=17

N+50=17*4=68

N=18

Answer 2

If the mean of 4 numbers is 17 then they add up to 17•4 = 68

16+16+18 =50 so to get 68 the other number (N) must be 18.

eighteen

Answer 3

The mean is usually found by adding up all the numbers, then dividing it by however many you have. e.g:

12,12,13,14

12+12+13+14 = 51

51 divided by 4 (number of data) is 12.75

The mean of this set of data is 12.75.

The question is asking you to find out what N is. So whatever happens, the 3 numbers provided plus 'N' divided by 4 is 17.

I'll leave the question for you to work out =)

Answer 4

The 'mean' is just a fancy word for 'average', (statistics).

Solve for N:

(N + 16 + 16 + 18) / 4 = 17

N + 16 + 16 + 18 = 17 * 4

N + 50 = 68

N = 18

So if the mean is 17, then N would have to be eighteen (18).

Good luck in your studies,

P.S. - I enjoy answering these kinds of questions... they're fun.

Answer 5

eight LETTERS?  But it's a math problem.  This makes no sense.
