Can someone explain this math problem to me?



The Official CLEP Study Guide says the answer is A. I thought the answer was C, though. I can't figure out why the answer is A. Can someone explain this to me or point me to a web site that explains this? I'm not a math guy, but this one seemed easy to me.

In addition instantcert I have been taking the free online petersen's mock exams to prepare for my upcomong American government clep exam, I was wondereing has anyone here used these mock exams and has it helped them along with instantcert to do well on the actual clep exam?
Thanks

On the DANTES Principles of Statistics review section: Question 15 in the Correlation topic.

The correct answer is "0" but the software rejects "0" as an answer. It only accepts "0."

Hey everyone im taking the college algebra clep in about 2 weeks does anyone have any suggestions on some good study tips?? and why hasent a instant cert course been made for this subject??

I recommend offering a discount for people review questions after taking the test. I took "Rise and Fall of Soviet Union" provided some feedback but there is no reason for me to go back and review the questions.

While I believe that this forum would be an improper place, an email review to the site admin with "yes, no, don’t remember," and additional questions could greatly increase accuracy of this site.

I'm studying for the American govt clep exam and I'm using the american government cliff notes book as a supplement. Has anyone here just used just instantcert to pass this exam? Thanks

I want to apologize to steve for the comments I made about the material that he has put togather. I let my anxiety about these test get the best of me. What happens is I take these paper based test and wont know the results for four weeks building up anxiety about wheter I passed or not. I passed US history 1 with the help of instancert and the collegeboard study guide and took US history 2 clep exam on Mar 8th and still dont know my results. I will be taking American govt clep exam on April 15th, someone that took this test reccomended that I use instantcert, pinkmonkey, and passyourclass, but I purchased the american govt cliff notes which I will use instead of pinmonkey. This american govt cliff notes book has recieved great reviews on amazon.com so check it out. I also wnat to apologize to listmanager as well.I will be taking the American govt clep exam at a local college via Computer. This is a test that is not paper based, my military eso never told me about this luckliy I found this info on the Dantes website.
Good luck to all and happy studying

I needed twelve credits to graduate in May, so I decided to take 2 Clep exams; Humanities and Social Sciences and History.

I passed the Humanities with a 53, without studying. I scored a 49:mad: on the Social Sciences and that was with the collegeboard study guide.

I am kicking myself because I didn't find out about instantcert until yesterday!!! I am planning on taking both of the U.S. History exams, is two weeks enough time with instantcert?

Has anyone ever used the RUDMAN "Red Cover" books put out by the NLC "National Learning Corporation" for the Civil War and Reconstruction exam? I am just wondering how similar in context are the sample questions in the book compared to the real thing? THANKS!!

Does anyone really know for sure how many of the dsst questions or clep questions really count in the grading equation? I know they both " field test" certain questions on each exam, but how many? I found taking the dsst exams interesting in that they have a hundred or more questions and yet require you to only score a 48 or 49 on most tests. Does that really mean that each question only counts one point or are they " field testing " ten or so and really grading you on 90 or so questions. I keep track on a scratch sheet how many questions I know I have right and usually when i get up around 50 or more I feel safe ...yet Iam not sure whether there is some curve factor out there that will ultimately zing me and six months later I can test again. Anyone know for sure..thanks.
