I always see companies advertising their products as "700% effective " or "the product kills 900% germs".
But percent means "out of hundred". So how can the percentage be more than 100 like 700% or 900%?




percentages percentile

    Some exact quotes may help. In some contexts, more than 100% would not make sense but in others it might. It might be more of a question of English than of maths. It depends on what 100% represents: some absolute limit that cannot be exceeded or just an arbitrary reference point which could be.

700% would mean that it's 7 times as effective than a previous product or another company's product.

  • @proneon True, almost everybody says 7X. I'm just nitpicking. By contrast, I do not recommend saying 100% more effective when what you mean is that there is no difference ;) (My comments are irrelevant to your question. Don't let them confuse you.)

    @proneon No, it's not really wrong. To say that something is $7$ times better is exactly the same, mathematically, as saying $700%$ better. Because $% = 1/100$ we have that $700% = 700timesfrac1100 = 7.$ Perhaps linguistically it may be confusing, though.

What is the equation of a 3D cone with generalised tilt?

Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite What is the equation of a 3D cone with generalized tilt? I've noticed that in most equations given to represent a cone, there is no parameter which defines the tilt of the cone in 3D space and that most of them have their point at the origin $(0,0,0)$ - I was wondering if anyone could give me a more generalized cone equation for a cone in any position in 3D space 3d share | cite | improve this question edited Jul 25 '16 at 0:05 ervx 9,425 3 13 36 asked Jul 24 '16 at 15:38 Charlene 11 2 2 Welcome to Math.SE!

Color the edges and diagonals of a regular polygon

Clash Royale CLAN TAG #URR8PPP up vote 5 down vote favorite 1 Here is the problem: For what $n$ is it possible to color the edges and diagonals of an $n$-side regular polygon with $dfracbinomn23$ colors, such that you use every color exactly three times and for every color the three segments (edges or diagonals) with that color form a triangle? Trivially $nequiv 0 text or 1 pmod3$. I can also prove that if the statement is true for $k$ than it is true for $3k$ as well. How to finish? Please help!

Relationship between determinant of matrix and determinant of adjoint?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite We are studying adjoints in class, and I was curious if there is a relationship between the determinant of matrix A, and the determinant of the adjoint of matrix A? I assume there would be a relationship because finding the adjoint requires creating a cofactor matrix and then transposing it. linear-algebra determinant adjoint-operators share | cite | improve this question asked Nov 17 '17 at 17:32 CluelessCoder 32 5 For a square matrix $A$ of order $n$, we have $A(operatornameadj A)=(operatornameadj A)A=|A|I_n$ where $I_n$ is the identity matrix of order $n$. This should tell you about the determinant of the adjoint in terms of that of $A$ (use multiplicative property and other elementary properties of determinants). – Prasun Biswas Nov 17 '17 at 17:35 1 @CluelessCoder: see here: math.stackexchange.com/questions/516127/…...
