We are conducting a test on a rare disease. A positive result means that, according to the test, the subject is infected. The following characteristics are known about the test and the disease: If a person is infected, the person has a $95\%$ chance of testing positive. When a healthy person is tested, the test has a $99\%$ chance of giving a negative result. A mere $0.1\%$ of the population is infected with the disease. If a person is tested positive for the disease. What is the probability that the person actually has the disease? I don't understand how to write the conditional probabilities if someone can explain to me than I should know how to solve it, but I'm not sure how to convert the text into the mathematics language. What are sentences like "the longer X, the more Y" called and can they be used in formal written English? What is the type of sentence exemplified below called? Is it appropriate to use it in a scientific paper and formal written English in general?     1. The more pronounced the variation, the   more the waste.      2. The more you give, the more you get.      3. The longer I live, the more I realize the impact of attitude on life. Is there a way to render an object with a subdivision surface modifier with a wireframe which is the original geometry as well as the wires that make the subdivision surface?  Example:   This wireframe here is curved. What if there was displayed the straight wireframe. The wires that make are made by the subdivision surface. Thats what I want to achieve. How to do it?  What I mean is - How to render the curved wireframe (which is the original geometry with the straight wireframe (which is the wireframe the is made by the subdivision surface)? Is it safe to use the command apt-get autoremove in this particular scenario? Can you use Magical Secrets to choose high level spells when multiclassing as a Bard? Say you have a Wizard 7/Bard 9. You gain your 17th level and choose to gain the level in Bard (which grants you Magical Secrets). According to the Multiclass Spellcaster: Spell Slots per Spell Level table, you now have a single 9th level spell slot. Can the spells you choose from Magical Secrets be 9th level spells even though you can only cast up to 5th level Bard spells? What suggestions should I make when reviewing a poorly written paper? Since I need a break from the reviewing...  Often in my field I review papers from researchers in Asia (reviews are not double blind) which are poorly written. By poorly written, I don't mean that the prose is not pleasing to the eye, that there are problems with how the writing flows, or that there are innocuous typos or spelling mistakes. Instead, the grammar used by the authors differs seriously from normal English, and often produces significant changes in the meaning of sentences.  Usually such papers are ultimately readable, but one has to go back and re-read sentences or paragraphs several times to infer the meaning (and this is with strong knowledge of the research area!), so I generally won't reject a paper solely for this reason. However, I would feel remiss in my duties as a reviewer if I didn't instruct the authors to improve this aspect of the paper. I'd like to provide helpful advice for the authors without just giving them a laundry list of the errors.   Typically I highlight a few places where I had significant trouble understanding what they actually meant to say, and suggest seeking a professional editor before publication.   Are these reasonable things to suggest?   What other suggestions can I make? Layover at Dusseldorf and Frankfurt, category A or B visa? I am a Indian citizen in the United States on a F-1 visa.  For the summer break, I am traveling (round-trip) from Chicago to New Delhi via Dusseldorf-Frankfurt by Lufthansa airlines. My onward Journey would be on July - 8 and return Journey on Aug - 11.  My layover will be of 1 hour 10 mins in Frankfurt and 3 hours in Dusseldorf.  I would like to know if I require Category A or Category B Visa. If not, what type of visa do I require for the Schengen visa for my transit. How I can apply for the same?  I tried to find slots in German consulate but all slots are full before my departure date. If I don't get the Schengen visa, I cannot travel and will loose all the fare (since my ticket is a non-refundable ticket). Is there any other way I can tackle this situation. If integral is zero and function is continuous and non negative, then what about the function? Which view is the "Current view"? I have got a SharePoint 2010 website with a WebPart-page and a few WebParts on it.  One of the WebParts displays a list/a view of a list.  The views of that list have been updated due to business needs - but the view in the WebPart on the WebPart-page is not updated.    If I edit "Modify Shared Web Part" (the one with the list / list view),  the "Selected view" is set to "&lt;Current view&gt;".  My question is now: Which view of the list is the "&lt;Current view&gt;"? Is it any view of the list at all - or has the WebPart some kind of its own view to that list? Converting from shapefile or raster formats to LAS? I'm hoping there's something in the same conceptual space as the old VB6 IsNumeric() function? ParametricPlot3D and Sphere Graphics Boolean variable returns as string from javascript function Noun-adjective reversal - was it ever in use in plain speech? Converting point layer to raster grid that shows frequency of points per cell uisng QGIS I have a point layer that shows the distribution of a species.   Is it possible in QGIS to convert this point layer to a raster grid in which the value of each cell corresponds with the amount of points within that cell?   Until now, I only managed to attach attribute values to the grid cells. I have already added a column in my attribute table that has the value '1' for each point, hoping that there is a way to use a sum of attributes for each grid cell. Securing WMS against unauthorized access? In a project the customer wants the images of the WMS to be secured against unauthorized access.   What are the common solutions to realize that?   Are they compatible with the OGC-standards? gpgkeys: key C927EBE00F1B0520 not found on keyserver Possible Duplicate:    I am using 10.04 LTS - Lucid Lynx.
