The equation for the determination of the z-score is shown below.
                                 z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation. 
Substituting the known values,
                                 z-score = (1,030.00 - 1,200) / 100  = -1.7
Therefore, the z-score of 1,030 is -1.7.

Simplify into one logarithm 2 log x + 3 log y
const2013 [10]
If a logarithm has a coefficient, then the coefficient can also be written as the exponent of the input of the logarithm. In other words, if you have the logarithm alog(x), that is equal to log(x^a). So the expression can be rewritten:

log(x^2)+log(y^3)

If tow logarithms of the same bases are added together that is equal to the logarithm of the product of the inputs of the two original logarithms. In other words, given log(x)+log(y), it can also be written as log(xy). So the expression can be combined into one logarithm:

log(x^2 * y^3)
