Sheesh...grammar freak. lol Hahaha...I say never put all your eggs in one basket! Seems like shy and avant are the only tutors in this thread...
Thx for making me feel old, no really, it's much appreciated -_-2 ... good thing there's the thread about the 30 yr olds -tongue2
yeah, but honestly, I'm kinda glad that she ditched the other forum hehehe otherwise, who would help me with my homework? LOL j/k! lol just because you're a tutor it doesn't mean you're old! At least we know you guys are smart . Anyway, I need some more help please! Find the equation of a line that both passes through point (-4,5) and is parallel to the line of: y= 1/2x-2 Aiya I hate algebra! Actually I hate all math in general. Seriously, how are you guys so good with math? And wait until I get to calculus and linear algebra!!! I'm going to die. I don't understand why they have to make us study this stuff. I mean it's not like we're going to use it in everyday life or something....ugh. p.s.: The answers you guys (shy+avant) gave me for the 2 math problems were correct! Thanks again.
-detect For a line to be parallel, it needs to have the same slope. In this case, it's 1/2. So you're looking for a line y= (1/2)x + (a number) which follows the general form y=mx+b. You are given the point (-4,5), so we plug it into what we do know and find out what the number is. 5 = (1/2)(-4) + b 5 = -2 + b 7 = b Now that we know what b is, we put it all together. y = (1/2)x + 7 Ta Dah! I use to like math as a little kid, I hate it now. I'm taking differential equations this semester -dead
You useD to like math as a little kid, not "use". Since you are speaking of the past, you will have to use the past tense form of the verb. So, we know now that you're doing pretty well in math class, but how are you doing in english? True, calculus and linear algebra are not used in every day life, but you're not required to take such classes if you are not going into a field which requires the usage of these techniques. If you're an engineer, you will find that calculus is quite an integral part of your job. If you're in investment banking, you will find that the application of calculus and the theories based on calculus are very useful (brownian motion, etc.) If you're an actuary, you won't pass an exam if you don't know calculus. If you're majoring in liberal arts, these things will not be of any use. As I'm working on the trading desk at a large investment bank, calculus and financial theories based on calculus are used extensively. My sister works at an insurance company, & she uses it even more, just with different applications.
Wow, thanksssss avant! Now that I know how to do that problem, I'll be able to figure out how to do the rest. Hopefully it doesn't get too much harder -sweat yeah shy, since I'm thinking about becoming a vet, I guess I better start brushing up a lot on my math! Gosh, this is so depressing. lol -ohmy! shhhh...shy! Don't insult him before he gets pissed and doesn't come in here to help me any more... hahah
I think that u don't have to worry about that Avant is not going to help, because i think that he's allways ready to help girls am i Right AVANT? BTW mystery i used to be good in match too but my english just suck >.< .
Alright there miss smarty pants, don't feel so proud yet. Only thing you've figured out is that I don't double check my posts. Take that -noclue ! Wow mystery, didn't know you thought I had such short temper... and to get offended by SHY of all people, come on! I probably take what YOU say with more weight -rotfl HAHAHA. You are VERY wrong there bud. Do you think I'm some girl puppet or something? I only help those who I feel like helping. Plus most women are annoying, so I have no reason to give them any special privileges. They should be worried... -devil
Omg I'm also an idiot on math! But this question is for my brother. FOr his project it told him to cut 19 11/16" so umm how big is he supposeD (lol got that from shy haha) to cut it? The 11/16" threw us off.. help please
Wow, what an excuse… BUT, if that’ll make you feel better, then ok... let’s just say you never double check your posts. I don't quite understand your question with the whole cutting thing. What exactly is your brother trying to cut? Anyway, 19 11/16" = 19 11/16 inches... = 19.6875 inches (you divide the 11 with the 16), which is more than 19 and 1/2 but less than 19 and 3/4? I'm not sure with what you guys are trying to cut, but whatever it is, I'm sure that it doesn't need to be THAT accurate, so long as you come close to the given value.
yeah thanks for the help guys! oh and Avant...the answer to # 8 and 11 was actually: #8. Everybody was satisfied with __________ grade. a. they're b. there c. their d. their own e. her #11. He wants to __________ where no man has gone before. a. go boldly b. gone boldly c. boldly go d. go with bold e. go bold Just thought I'd let you guys know
LOL! You 2 are too funny. Insulting each other -lol And I was just kidding about what I said... of course I didn't think you were that petty! Anyway, I should be studying for math right now -sweat
Hmm did your teacher give you an explanation as to why the answers are what they are? I'm having trouble figuring out why the answer to #11 would be (a).
Yes! It worked... all fear the clubbin action smilie. Well then, it looks like I'm fired as an English Tutor... >.< Anyone have physics questions? I'm good with physics, lol.
Peachey: For stats - Neither of the examples given are considered random. Random sampling occurs when everybody has an equal probability of being selected to be in the sample. When you line people up from shortest to tallest, you are already putting bias into your sample. There should be no order in random sampling. For chem - let 'n' represent the number of moles 1) So for methane: n = mass of methane / molar mass of methane = (15g)/ (16g/mol) = 0.9375 mol For oxygen: n = mass of oxygen / molar mass of oxygen = (50g)/ (32g/mol) = 1.5625 mol In the chemical equation, the ratio between CH4 and O2 is 1:2 the actual ratio given the two masses is 1:1.6667 So the limiting reactant is O2. 2) Use the limiting reactant to calculate the amount of product produced. so for two moles of oxygen, two moles of water are produced, giving the ratio between the reactanct and product 1:1. So # moles of O2 = # moles of H2O 3) Use limiting reactanct for calculation: mass CO2 = #moles of O2 * 1mol CO2 / 2mol O2 * molar mass of CO2 The 1mol CO2/ 2mol O2 is the ratio of moles in the chemical equation - used for cancelling units. 4) Given that oxygen is the limiting reactant and the oxygen is totally consumed, the number of moles of methane remaining is given by: #moles of CH4 - # moles of O2 * 1 mol CH4/ 2mol O2 5) Since we assumed that the oxygen is totally consumed, no oxygen remains after the reaction occurs. Organic chemistry is really not that hard if you do a lot of practices. Good luck on your finals.
She beat me to it! -pirate Arrrrg People have tendancies that makes it nearly impossible to do a real random sample. Examples: If the instructor spins faster at times and slower at times, it'll be bias. If the instructor thinks about how much time before he picks, then he's bias. If the teacher starts off facing a group of students, he's bias. If he's familiar with the room and can tell which direction he's facing while blind folded, then he's bias. If a student is super chunk while another student is a super skinny, then the skinny kid won't be as likely to be picked. Some students will probably be closer to the instructor than others, yada yada yada... Even computer randomization isn't perfectly random, but it gets pretty darn close.
omg...Shy and Avant are nerds! lol And why does a trading deskee have to know organic chemistry?!? I would have helped those cheaters...but I attempted organic chem 4 (yes you heard right) times...lol.
I don’t HAVE to know it, I just do. I was actually aspiring to become a pharmacist before I decided to switch majors and landed with this job.
