Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:

Why researchers are interested in describing measures of the center and measures of variation of a data set?

Let Χ be a real-valued character (mod k). Let k S = Σnx(n). n=1 If (a, k) = 1, ax(a)S = S (mod k). (iii) Write k = 2ºq where q is odd. Show that there is an integer a with (a, k) = 1 such that a = 3 (mod 2ª) and a = 2 (mod q). Deduce that 12S = 0 (mod k).
