Solve Weighted Averages Problem in SAP BW Warehouse

AI Thread Summary
The discussion revolves around a mathematical problem in SAP BW Warehouse software, where the user seeks to adjust a results row to achieve a specific sum of 92.31447 in column E, instead of the current 103.350. The user provides a dataset with five columns (A-E) and expresses confusion over the calculations, particularly regarding the meaning of terms like "X/Y" and "CxD." There is skepticism about the validity of the values in columns A and B, which include very small numbers for quantities. Participants emphasize the need for clarity on how the desired figure relates to the existing data to provide a meaningful solution. The conversation highlights the complexity of deriving a formula without understanding the underlying context of the numbers.

Column-----> A------- B-------C-------D---------E
Beds------> 21.0-- 181125 - 0.0001 - 95600 -- 11.08405797
Balls------> 180 --- 39255 -- 0.0046 - 17715 -- 81.23041651
Results----> 201---220380 - 0.0009 - 113315 - 103.3501906
sum sum X/Y sum CxD
I have the above problem on a program I am writing and need the mathmatical solution to get the right results row. This program is used in the SAP BW Warehouse software. The program deliveries the above result. It calculates the the result row by the formula below the results row. What I want to get to is for column E to sum to 92.31447 and not 103.350. The program for programmable reasons cannot sum the two rows so I need to derive a formula with the figures above to get to the desired result of 92.31447
Any help will be appreciated. I am just about off my head! :bugeye:
Cannot get the formating correcthence the ---. Basically I have 5 columns A-E.

I THINK what you mean is that the "Results" row under the "A", "B", and "C" columns is the sum of the two numbers above it, but I have no idea what X/Y means since there is no X and Y. I also don't know what CxD means since "C" and "D" are columns of numbers, not numbers. I'm wondering how in the world the number of "Beds" could be 0.0001 or how the number of "Balls" could be 0.0046!

In any case, all you are telling us is that you WANT 92.31447 in the last column without telling us WHY or how that number is supposed to be connected with the others?? One perfectly valid formula for that result is "92.31447"- in other words whatever the other numbers put 92.31447 in that place. Without knowing what in the world you are doing or what these numbers are supposed to MEAN that's about the best we can do.
 
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
