1: Either one could be -ve and rest two +ve or all could be -ve. so nsf.
2: If x is -ve, y is +ve and vice versa.

Togather: z has to be +ve and one of x and y is +ve and the other is -ve.

Suppose, x = -10, y = 5 and z = 6, no.
x = -10, z = 1, and y = 5. yes.

Anyway to set up the distance as an inequality |x-y|>|x-z| and solve algebraically?

each statement individually not sufficient

combined

xyz < 0 and xy < 0
--> z >0 and xy must be opposite signs

given condition |x-y|>|x-z|
y---0--z---x --> here z is lie between x and y and satisfies |x-y|>|x-z|

y---0---x---z --> here z is not lie between x and y satisies |x-y|>|x-z|

two possibilities
not sufficient
