Determine the density function for coefficients of equation
Determine the probability densities for coefficients of equation
I worked on a Word document and also saved the file on my flash drive.  When it asked me to save, I pressed the Replace document option by mistake.    I can see the missing work under the Properties menu. Will I be able to recover the lost work? Can I have multiple primary keys in a single table? Can I have multiple primary keys in a single table? How to display random jokes from www.icndb.com in your terminal? I already know that you can get some nice quotes/jokes using the  program.  But I've found in this  a new source of fun that I'd like to have when I open a new terminal.  This time the jokes come from . My teacher proposed this question as a challenge proof to do on our own and I can't seem to get it. Was Wondering if anyone could give me a hint or help me on the process to completing it.  Let $a \in \mathbb{R}$. Let $f$ be a function defined, at least, on an interval  centred at $a$, except possibly at $a$. Let $L \in \mathbb{R}$.     If $\lim\limits_{ x→a-} f(x) = \lim\limits_{ x→a+} f(x) = L$   then $\lim\limits_{ x→a} f(x) $ = $L$.    We are supposed to prove this using the "delta-epsilon" proof style. Thanks in advance!! While dabbling in Clojure I've written a very basic program to echo whatever the user types into it. However, it doesn't run in a way that I'm perceiving to be natural. Here's the code:  (defn goo []   (print "echo&gt; ")   (def resp (read-line))   (print resp) )   I would expect the code to run like this (for me typing in foo as the input to read-line):  user=&gt; (goo) echo&gt; foo foonil   But instead, the echo and read-line is switched:  user=&gt; (goo) foo echo&gt; foonil   Why does this happen? Is there a subtlety I'm missing?  EDIT: From Joe's answer, the updated correct solution is:  (defn goo []   (print "echo&gt; ")   (flush)   (def resp (read-line))   (print resp)   (flush) )   Also, the flushes aren't necessary if you use println instead of print. What do I do if I don't have a META-INF folder or minecraft.jar? I have looked all over the Internet for solutions but I have got nothing.  I want to install the minepainter mod but I need a META-INF folder and a minecraft.jar. Possible Duplicate:          I installed the IE10 beta on Windows 7.

Please stop using SoftwareEngineering.SE as your toilet bowl Stack Overflow users have been using the "off topic - belongs on SoftwareEngineering.SE" close reason as an alternative to all the other close reasons. It'd be helpful if people actually read the FAQ and the six  before voting to migrate questions like:   , no redeeming value to favorite lists that become argumentative , "help my exact situation" questions are too localized , fails 5 out of the 6 guidelines , fails 4 out of 6 , too localized and too vague , too broad   Absent a reversal of the Stack Overflow community from viewing SoftwareEngineering.SE as the Stack Overflow cesspool, can the "off topic - belongs on SoftwareEngineering.SE" close reason be removed in favor of manual migration by moderators who can actually spend the 10 seconds to determine if the question should be closed outright first?    To say that SoftwareEngineering.SE is such a nebulous place and nobody knows what its scope is as the reason why crappy questions keep getting migrated there is to miss the point. Good questions are good questions on all of the sites, and questions that are too vague, that are too argumentative, too localized, and too broad are universal close reasons. There is no special dispensation for SoftwareEngineering.SE to have bad questions, even if you personally think the questions on there suck.  Even the six subjective guidelines for subjective questions are universal guidelines: they affect all sites. So even if you had no idea what the consequences of using the "off topic - belongs on SoftwareEngineering.SE" close reason were, there are still all of the other close reasons for which bad questions, like the ones above, can be closed. Entity Query field condition for Webform submissions Find all $n \in \mathbb{N}$ such that $\phi(n) = 4294967296=2^{32}$.  I managed to find that $16106127360$, $8589934592$, $10737418240$ and $12884901888$ are solutions for the equation, but I do not know how to find all of them. I was asked this question in an interview.  Lets say we have a correlation matrix of the form \begin{bmatrix}1&amp;0.6&amp;0.8\\0.6&amp;1&amp;\gamma\\0.8&amp;\gamma&amp;1\end{bmatrix}  I was asked to find the value of gamma, given this correlation matrix. I thought I could do something with the eigenvalues, since they should be all greater than or equal to 0.(Matrix should be positive semidefinite) - but I don't think this approach will yield the answer. I am missing a trick.  Could you please provide a hint to solve for the same? Audio is working, but the speaker test doesn't work I've installed Ubuntu 12.04 LTS from a minimal cd on a netbook (Asus 1001 PXD). I've installed the ubuntu-desktop package using the --no-install-recommends option.  Everything works fine, except the "sound test" for headphones or analog speakers.  Clicking on the "test" buttons (front left and front right) I don't hear any sound. Despite this, the audio is working properly.  I've checked the audio levels with alsamixer; I have also checked that the test sounds actually exist in /usr/share/sounds/alsa.  I tried an installation of Ubuntu 12.04 LTS made with the desktop-cd, and in this case the speaker test works properly.  I suppose, therefore, that the problem could depend on the lack of a package, but I have not identified which one. Solutions of $x^2 \equiv 1 \pmod N$ I am stuck with this exercise:     Show that $\forall s &gt;0 \quad \exists N &gt;0$ such that $$x^2 \equiv 1\pmod N$$ has more than $s$ solutions.   I think I cannot use the theory if quadratic residues, because the modulus is not prime, so maybe I must prove it with square roots or roots of unity, but I don't know how to approach it at all.  Thanks for any help. Why is this match pattern unreachable when using non-literal patterns? Are collective nouns always plural, or are certain ones singular? I'd say Microsoft have a way of bending the rules and I know that McLaren have won the championship. While this sounds strange, I believe it is correct English (sorry, I'm not native).   But when it's a small company, would you still use it this way? Is a company always plural, or are small companies singular? I.e., would you say Bakery Johnson makes fine bread or Bakery Johnson make fine bread? Is it My book seller, Woody's, have moved or is it has moved?
