--- Quote from: Fig on 07 Feb 2015, 11:46 ---2. To pass your math class, you must obtain a grade of 70% of the total points possible. The points can be earned through the following: Six tests worth 100 points each, various online assignments totaling 235 points, and one final worth 200 points. If a studen wishes to skip all the online assignments, what is the minimum test and final percentage average that must be obtained to receive a passing grade? Two parts: A. Write the inequality that would model this scenario and B. Solve the inequality.
-The most I got with this was 'something' ≥ .70(1035).

Okay, you want to calculate how many points you need to pass first. The total points are
6 * 100 + 235 + 200 = 1035. You need 70 % of that - that is, 0.7 * 1035 = 724.5. Without the online assignments, you can earn 6 * 100 + 200 points tops (so 800 points in total). As we said, you need 724.5 of 800 points - that is 724.5/800 = 0.905625 = 90.5625 %.
I am not quite sure what inequality they are looking for. I suppose something like
x >= 0.7 * (6 * 100 + 235 +200)/(6 * 100 + 200) where x is the desired average?
Carl-E:
Actually, probably the simplified version,
(6*100 + 200)x > .7(6*100 + 200 + 235).
And, since you know the equation for #1, I think we're done!
We probably didn't help all that much, though. Let us know where we're unclear, or anything else you may need... :-D
Loki:
I am afraid I am also not doing a very good job at explaining. I am decent at solving, but I have no idea if you understood my trail of thought.
Carl: how is the equation where the x is not alone on one side "simplified"? :psyduck: (I know you are probably right, I am just confused)

9 students have died at my university since the beginning of the academic year. 4 from suicides, 2 from car accidents, 1 from a seizure, and 2 where the cause hasn't been released.
I feel bad for the administration, a little bit.
Personally I think 4 suicides (among a population of about 17K students) is an indication of a problem, The counseling center needs to be improved. It's frankly not great, they have very limited walk in hours and according to a friend don't offer grief counseling. And the administration is trying to reach out to students.
But the university has had to deal with people going full conspiracy theory on them. Facebook postings about serial killers or the occult, parents threatening to pull their kids out of school, a certain group of students trying to pin all 9 deaths on the administration. Hell, the university isn't even obligated to inform students of deaths that occur off-campus (which is where all but one occurred), they just do. So I'm not even 100% sure how it compares.

In unrelated but still university related news, I was able to sidetrack Friday's entire Arabic lecture by emailing this video to the professor:
http://www.youtube.com/watch?v=1PlAGdkZhos
The title of the song, for those who don't speak Arabic, translates to "We Have Ministries." And it's basically about government corruption and inefficacy in Lebanon, making heavy use of an art form that the Lebanese have perfected, sarcasm. So after playing it at the beginning of class, someone asked about free speech in Lebanon and about if there was any sort of retaliation against the band for that song (there was not).
That led the professor, who is Tunisian, to talk about what her life was like pre-Arab Spring in Tunisia and share this video:
//www.youtube.com/watch?v=IeGlJ7OouR0
Then a student asked about the French words that appeared in both songs. Which led to another discussion, the professor's realization that the lesson she had planned wasn't happening anymore, and the playing of this TEDTalk (you can turn on English subtitles, it's actually extremely interesting and applicable to languages other than Arabic)
//www.youtube.com/watch?v=bNOiwgrZbPE
So I unintentionally created the world's best Friday class, (other than one that is cancelled) one composed entirely of YouTube videos. Although now she wants us to write a response to the TEDTalk.
