Gracias. Thanks for confirming. That's how I felt; it was a positive Ed. I have a few other questions I need to bring up with my professor as well. The questions are poorly worded, quite frankly

If the value of price elasticity of demand is 0.2, it implies that a 1 percent increase in price leads to a: Again, I know that technically I'm right. I just don't like an environment where the validity of a question depends on my supposition of what "most" cases are.

Homework Statement So, my professor gave a test this weekend. I missed a problem concerning price elasticity of demand, but that's only because I assumed the opposite direction. Now, I'm considering challenging this question, because the price elasticity was listed as a positive number...

Hello all, Well I work for a company that typically gives a sign on bonus for new hires. However, I'm (hopefully) switching positions internally to a new department. Do you think I should expect a sign on bonus in this scenario? Thanks!

What do you think about a cover letter? I think it might be a nice touch to explain that I really want the opportunity.

I have an opportunity to get me on my career path that I plan to stay in. The position is within the company I work for, and I think I have a good opportunity to get it. As for etiquette, our company is generally business casual (button up/polo) but we get to wear jeans. However, on the day...

Hello, I'm trying to use a moving average to optimize performance. However, I don't want to just choose an arbitrary period to begin with. Do you have any suggestions as to how to determine the proper period to begin with. What I'm asking is: Is there a mathematical formula to determine the...

Why you got to kick McDonald's when they are down?? ;)

I received a job offer I'm accepting, but my boss has been out of town this last week. Understandably, he is swamped today, but I have to tell him for the two weeks notice. So, my question is when should I tell him? At the first free moment? Thanks!

Is anyone familiar with the difference in pay for high school teachers vs. applying your skills in private sector workforce? For instance, are there tax benefits that teachers receive that can be quantified vs. those of say some analyst (if they make the same pay)? What about pensions? Are...

Hello, I would like to get your opinion on moving into programming. Basically, I want job security and the ability to work just about anywhere there are jobs. I've considered taking a job as a programmer, but I would like to know what you suspect the job prospects are for such position? From...

I would honestly have to say that like everyone else: it is just an internship. If you don't want to work in it full time, get a recruiter or just search the job boards. When you go into interview with those other companies, and they ask why you aren't staying, just be honest: you're passion...

Thank you both very much for your replies. Homeomorphic: I appreciate your input, particularly concerning not spending the money to do the courses if I don't need to. I've been working to develop my knowledge outside of the classroom when I get home from work. jkl71: Thank you for providing...

I guess I should state that I currently have my mathematics bachelor's from the University close to where I live. So it's not that I only did an online college; my first degree was at a state university.

Hello, I'm currently working as an actuary, but I am considering switching to a computer career of sorts. Let me preface first by saying that I do not intend to belittle or pigeonhole such a career by the way I speak about. For instance, it's kind of annoying when people talk of actuaries in...

Thank you all for your replies. I'm looking at the business site and it says, "Stipends for graduate assistantships start at approximately $6,000 - $6,500 per 9 month academic year for master's students and approximately $13,000 - $18,900 per 9 month academic year for doctoral students, with a...

I currently have my math degree, and I am working in the actuarial world. However, I'm considering returning to school to study quantitative finance, because I like economics and it will give me exposure (without requiring ph. D for a job). Unfortunately, I'm in mostly financial constraints...

One of my primary motivations for moving to teaching is that my summers would be "open". One of my goals would be to spend my summer months either in inner city or overseas areas teaching underprivileged students. I really don't want to teach high due to politics and the terrible education...

Hello, I've come to the point where I realize: I'm supposed to teach. I've tutored for years, taught small groups, etc. Also, I want the summer to pursue my other interests. I don't want to do research or anything; just teach. I was just curious as to how competitive these jobs are...

Homework Statement Hello all, I am doing problem 2.1.15 from "The Mathematics of Investment and Credit" 5th ed. I'm having trouble with the PV solution...I think I may be counting my days wrong. Here is the original problem: Since June 30, 2007 Smith has been making deposits of 100...

Yes it is. Thank you for your help :)

Homework Statement I want to compose the relation "equality" with the relation "less than" in the form: equal o less than. Homework Equations The Attempt at a Solution Firstly I determine the y in (x,y) such that this is true. Graphically, it is just the values less below y=x...

Thats the way I tried it the first time. But I was thinking they might have been asking for individual claims that exceed the total expected premium. So I wantes to verify if their solution ia actually an approximation of what I did. Thanks!

Homework Statement The total claim for a health insurance policy follows a distribution with density function f(x) = (1/1000)e^{-x/1000}, x>0 The premium for the policy is set at 100 over the expected total claim amount. If 100 policies are sold, what is the approximate probability that...

I am wanting to gain experience with SQL without buying a license. I am planning to buy a program that shows you how to create databases as well as write code for them. However, this program requires that I have an SQL setup to use. I saw that Microsoft has a MySQL download but I'm not sure...

Thanks again for your reply. I will be registering for my first exam hopefully by March! Have a great 2013!

Thank you for your responses. Currently, I am interning as an ops analyst at a distribution center. I don't plan to stick in operations, however. Do you think the fact that I have a internship experience--though it's not in insurance--will work in my favor?

I am currently graduating from the University of Texas at Arlington with a 4.0, and I have my BofSci degree in math with an emphasis in ops research. I'm preparing for my actuarial tests, and I'm not worried about passing them. However, I know it's a bit of a tight market. I was considering...

I agree, but I believe the question is just of a general type. I went off the assumption that the OP is in a class that is assuming a constant rate at this point. Otherwise, we would need a proposed "deceleration rate".

Correct on the 2 year/ planetary system(per 1 galaxy)--otherwise known as .5 planetary systems/year or 1 ps every 2 years. That is for our galaxy. Now, under the assumption that our galaxy is like the other 100 billion in the observable universe, then in each galaxy we expect to see .5...

Ah ok! My book mentions that every subset of a discrete space is closed, but it doesn't explictly say that it is open when we first discussed them. It mentioned the topology is that every set is open...so I suppose it's implied. Thank you!

Homework Statement Prove that every Hausdorff topology on a finite set is discrete. I'm trying to understand a proof of this, but it's throwing me off--here's why: Homework Equations To be Hausdorff means for any two distinct points, there exists disjoint neighborhoods for those points...

Thanks again! This site is amazing!

Thank you! Wouldn't it just be based on the density of the rationals? Also, thank you for catching my typo :)

Homework Statement Let X:=ℝn with the Euclidean Topology. Is X first countable? Find a nested neighborhood basis for X at 5. Homework Equations If X is a topological space and p\inX, a collection Bp of neighborhoods of p is called a neighborhood basis for X at p if every neighborhood...

Homework Statement For my proof, it tells me that f:X->Y is bijective. I understand that it is one-to-one and onto, but I just want to be clear about this from a neighborhood (open subset by our def) standpoint. Just to be clear: if f is bijective continuous, then that means the for all open...

Straight up, I want to be a Chief Office eventually. I can concentrate the SEM MS into many categories--probably choosing healthcare for a few reasons--including their high salary and necessity. However, what about Supply Chain Management...honestly, I don't like the idea of working in a...

Also U intersect A for that first proof wasn't empty because p is an element.

Firstly, thank you for all of your help! I wanted to give one more try at this. I think I have it now! (This time for real lol) Spse p\in\deltaA If p\inA, Then \forall open U\subseteqX s.t. p\inU, U\capA≠∅. Since A is closed, \forall open U\subseteqX s.t. p\inU, U\capA is not a subset...

I "think" I have it now. I finally discussed the closure of X\Int A, thus it has SOME neighborhood not contained in it--thus the intersection with Int A is not empty. As well, A-closure is closed, so U intersecting Ext A is not empty for SOME neighborhood. Does that sound right?

X is a topological space. A set S as a subset X is open iff there exists a set for all p in S, there exists and open neighborhood completely contained in S. I know this problem should be easier, I think I'm just at a point where I "can't see the forest because of all the trees." I'm able to...

I understand the contradiction, but I can't seem to grasp why the interaction with the int being empty causes the interaction with boundary to be empty. :\

I would like to try one more method. However, I the very last bits may need clarification: Assume for contradiction there does exist such a neighborhood that either V\capA = \phi or V\capA=\phi. Let p\in\deltaA Thus p\inX\A and p\in\bar{A} However, since X\A is closed, \existsV\subseteqA...

I'm sorry, I'm not quite understanding it. It looks like we want to show p being in the neighborhood AND the boundary, and then we discover it's not in their intersection. Is that correct? I'm having trouble see how that is the case though. These are my thoughts on that. We see that the...

I did the other leg by contradiction; it seemed a bit easier. I have shown that P is in the closed "neighborhood" of X\A and \bar{A}. So if I union them together we end up with the entire set X. I'm honestly a bit lost though on how to show the neighborhood portion of this. Do I need...

Lol, my professor is a stickler--but she is an excellent teacher! So she's only a stickler because she has covered the material. So hopefully I catch these things before a test---though we have a quiz coming up! If you have time, do you mind helping me with my other post? I'm not quite sure...

Excellent! Thank you for the help!

Should it state something like: Let p\inA, There exists an open set C'\subseteqA s.t. p\inC' Thus it's in the union of all open sets. Would that fix the issue? Thanks!

Homework Statement I tried to state the whole thing, but here it is again: Prove: A point is in the boundary of if and only if every neighborhood of it contains both a point of A and a point of X\A. Homework Equations Boundary def: X\(Int A \cup Ext A) Def of Int A...

Homework Statement If p has a neighborhood contained in A, then p is in the interior of A. Homework Equations Int A = \bigcup{C\subseteqX:C\subseteqA and C is open in X} By the books definition, a neighborhood is open. The Attempt at a Solution Let C'\subseteqA be a neighborhood of p...
