Intergral True or False?
953587
Both of these are false.  For the first, take the integral from 0 to 4 of X, and you'll see that the average value is 2.  Multiply it by itself (comparing f(X)=X=g(X)) and you get 4.  But the average value of X^2 is more than 10.  So since there is a counterexample, it's wrong in general.\n\nFor the second problem, think about the greatest integer function.  (This is the function that kills off any numbers after the decimal.)  Think about the graph, and use it to explain why #2 is not true always (though often.)

i dont think its true...u better check it with more reliable source

false,\nuse the identity and -identity,\nboth are invertible, but the sum is the zero matrix, that is NOT invertible.....

there has been alot of work on showing that at least a certain percent of zeros must lie on the line. I think we're up to around 90%. It is unclear to me as to whether or not a proof can be found in this way. My guess is no

I think A is true. (It makes sense - but I've never tried it in a transaction)\nI know B is false. (It deletes the data, but does not drop the table)\nI know D is false (From experience - done both many times)\nI don't know about C.\n\nI'll guess A...

I have no idea about the math, but I'm thinking the assumption is that the data are relatively correlated linearly.  There's a lot of math behind the wiki link.

1. True. \n2. True.\n3. True.\n4. False. A parallelogram has no symmetry at all.\n5. True.

certainly\n\n\ndx/dz= dx/du * du/dz and so generallay\n\ndx/dz = dx/du*du/dv........................./dz

- Yes exactly.\n- Its FALSE.\n-------------

Yes. the RHS of the first is equivalent to xor(P,Q). This becomes an inclusive or when the or(Q,...) is added. Not(P) as suggested above doesn't give the correct result when Q and P both = true.

The first part is correct.  If the numbers in the second part are correct, it is true only for an ideal gas.  Other materials have various densities in their liquid and solid states.

i think the false statement is C. as the degree of any number is always 1. i dont understand the statement b tho :S

With modern C++ compilers you do have the bool (note minuscules) type. You can declare it like this:\n\nbool myBooleanVariable;\n\nYou may assign literals to it (literals for the bool data type are 'true' and 'false'):\n\nmyBooleanVariable = true;\nmyBooleanVariable = false;\n\nYou may assign them the result of boolean operations:\n\nmyBooleanVariable = (a > 5) && (b < 2);\n\nYou may declare functions to return bool results:\n\nbool IsInvoiceCurrent();\n\nYou may also test for their values directly:\n\nif (myBooleanVariable) ...\nif (!myBooleanVariable) ...

It doesn't always have to be.  The values for the heat of fusion of ice that you are using were probably found using equipment sensitive to only two significant figures.  I have seen heats of fusion values that have had more than two sig figs, but they were probably found with more sensitive equipment.

Yes it is a function because by the verticle line test it only intersects that line at 1 point.  \n\n\n It is a pretty simple test.  if a verticle line hits the graph at more than 1 point it is not a function.
