JudyAh, how delightful! Let's see, for "x" we have "exclaimed" and for "z" we have "zealously stated." It's like painting a beautiful landscape with words, each one adding its own unique touch to the picture. Just remember, language is a wonderful palette to play with, so don't be afraid to explore and have fun!

What is transitive in math?
A mathematical property, ~, is said to be transitive over a set S if, for any three elements, x y and z x ~ y and y ~ z implies than x ~ z. For example, "is greater than (>)" is transitive, but "is not equal to" is not.
If log5 x equals z then x is?
logbase5 of x =z x=5^z
What is the most concise form of 5 y z y x z x z x?
5x3y2z3
How do you factorise brac x-y brac squared - z sqaured brac. stands for bracket?
(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z. So the factorisation is [(x - y) + z]*[(x - y) - z] = (x - y + z)*(x - y - z)
What is the difference between the mean and z-score?
There is little in common between the two. Any set of numbers can have a mean. A z-score the standardised version of the Gaussian (or Normal) distribution. If X is a random variable that is normally distributed with mean µ and variance σ2 then Z = (X - µ)/σ is distributed with mean 0 and variance 1. Z is said to have the Standard Normal distribution. The value of Z is the z score for the random variable X..
