有一道数学题是这样的：知x1、x2、x3、x4、x5、x6，y1、y2、y3、y4、y5、y6分别小于等于33。x1＝31，x2＝9x1＝31，x2＝4这两个条件矛盾了啊 还有3 8 3是什么意思 ... 知道这些数据中任何一个数值都有与之对应的一个数之和为34。

The correct answer is A=x1,x2,x3,x4,x5,x6,x6,x7,B=y1,y2,y3f:A→B is on to ∋f(x)=y2Exactly 3 elements x in is . This can be done in C3 7ways Remain A four elements in B2 elements∴24−2C1(2−1)4=14To ... The total number of functions f: A → B that are on to and there are exactly three elements 'x' in A such that f x = y 2, is equal to.
float d = (x1 - x2) * (y3 - y4) - (y1 - y2) * (x3 - x4); First you need to know about dot product of two vectors. Let X and Y be vectors of length 1 in the directions of x-axis and y-axis, respectively. Then define X*X = 1, Y*Y = 1, and X*Y = 0, which is a kind of multiplication (or just an operation) yielding the length of the projection of ...
Now I divided by -1 to each of the x1,x2,x3,x4,x5,x6. We call the new numbers y1,y2,y3,y4,y5,y6. Then which of the following is TRUE? ... =Max of (y1,y2,y3,y4,y5) (b) IQR of (x1,x2,x3,x4,x5)= IQR of (y1,y2,y3,y4,y5) (c) Median of (x1,x2,x3,x4,x5)= Median. Show transcribed image text. There are 2 steps to solve this one. Step 1. Given a sample ...
The output is {(y1/3, 0, 0, 0, 0, y6/5, y1, 0, 0, 0, 0, y6)} indicating that most of variables must be 0, x1 must be y1/3, x5 must be y6/6, and the variables y1, y2 can be whataver. The above uses linsolve because the system is linear in each of the unknowns.
