The XY problem is a communication problem encountered in help desk, technical support, software engineering, or customer service situations where the question is about an end user's attempted solution (X) rather than the root problem itself (Y or Why?

He is really interested in problems 3 and 4, but the answers to the easier problems 1 and 2 are needed for proving the answers to problems 3 and 4. 1st problem
Young student answers math test by drawing his thinking in a bubble. ... After answering this question correctly, this genius 6-year-old boy went on to tackle the test's next stumper, and this is ...
If the points in the joint probability distribution of X and Y that receive positive probability tend to fall along a line of positive (or negative) slope, ρ XY is near +1 (or −1). If ρ XY equals +1 or −1, it can be shown that the points in the joint probability distribution that receive positive probability fall exactly along a straight ...
Theory X and Theory Y also have implications in military command and control (C2). Older, strictly hierarchical conceptions of C2, with narrow centralization of decision rights, highly constrained patterns of interaction, and limited information distribution tend to arise from cultural and organizational assumptions compatible with Theory X.
In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.According to the theorem, the power (+) expands into a polynomial with terms of the form , where the exponents and are nonnegative integers satisfying + = and the coefficient of each term is a specific positive integer ...
To subtract a decimal number y (the subtrahend) from another number x (the minuend) two methods may be used: In the first method, the nines' complement of x is added to y. Then the nines' complement of the result obtained is formed to produce the desired result. In the second method, the nines' complement of y is added to x and one is added to ...
