Irresponsible Blogger

Sorry about the lack of posts lately. Over the past two weeks I have had tests in 4 of my 5 classes and have the 5th one on wednesday. Throw in the fact I still cant figure out how to solve the type of problems that are going to be on that test and school is definitely stressing my out more than usual. The good news is my average on those four tests is 81%, and that includes on VERY bad score. Throw out the outlier and it jumps up to an 88% average. Alec, I challenge you to figure out what that other score was and post it in the comments. It will be embarrassing, but also show what a geek my best friend is! :)

Geek man to the rescue. Good job on those tests, 88% is a good average (excluding the 60 that you got on one test, of course). Kick butt on your next one. Buena suerte.

60 is incorrect...

LOL. College is tough. Well, not for me but for other people ;)

Alec- I thought it was a 60 too.

(1/4)*(X1+X2+X3+X4)=81 because you said that average of your four tests is an 81.

X1+X2+X3+X4=324

Let X4=Your worst grade, so...

(1/3)*(X1+X2+X3)=88 because the average of your best three tests is 88.

X1+X2+X3=264

We plug this into our first equation to get

X4+264=324

X4=60%

The only way that this is wrong is if you didn't put in the EXACT averages of your test scores (i.e. 88.3% or 80.6% for all 4...) The math speaks for itself.
