Three quasi-binary phase systems, BiSX1xYx (X, Y = Cl, Br, I; 0 < x < 1), have been investigated by X-ray powder diffraction. All three systems show unlimited solubility. For BiSCl1xBrx and BiSCl1xIx, strong positive and negative deviations from Vegard's rule are observed with respe...
Only (1): 2(x-y)=1 x-y=1/2 x>y Only (2): x/y>1 |x|>|y|;x and y are both positive/negative Both (1) & (2): x>y,|x|>|y| and both positive/negative -- x>y>0 Both statements combined is sufficient enough.Choose C.
Positive and negative values in the 4 quadrants Depending on the location of the point in one of the four quadrants on the coordinate plane, the x and y coordinates will have positive or negative values. If the x coordinate is in the left part of the plane, it has a negative value, an...

Prove that if x and y are both odd positive intergers then x^(2) +y^(2) is even but not divisible by 5.
The covariance is a measure of how the two random variables vary with each other linearly. The covariance can be negative unlike variance. The formula to calculate the covariance is given below as: Cov(X,Y)=E(XY)−E(X)E(Y) Answer and Explanation:1 ...
aA positive X value will shift the Envelope to the right and a negative value to the left. A positive Y value will shift the Envelope up and a negative value down. The Width and Height of the Envelope remain unchanged. Only the XMin, YMin, XMax, and YMax are changed. 正面X价值将转...

Then take the square root of both sides. x = 9 (or negative 9, but it doesn't work here). So, in your question, if x/y = y/z, cross multiply and y2 = x•z, so take the square root of both sides and y is the geometric mean. Upvote • 0 Downvote...
