PAIR OF LINEAR EQUATIONS IN TWO VARIABLES
ncert.nic.in(A) Main Concepts and Results • Two linear equations in the same two variables are said to form a pair of linear equations in two variables. • The most general form of a pair of linear equations is a 1 x + b 1 y + c 1 = 0 a 2 x + b 2 y + c 2 = 0, where a 1, a 2, b 1, b 2, c 1,c 2 are real numbers, such that 2 2 22 ab a b11 22+ ≠ +≠0, 0. • A pair of linear equations is consistent if ...

surgicalcriticalcare.netANALYSIS OF CONTINUOUS VARIABLES / 31 CHAPTER SIX ANALYSIS OF CONTINUOUS VARIABLES: COMPARING MEANS In the last chapter, we addressed the analysis of discrete variables. Much of the statistical analysis in medical research, however, involves the analysis of continuous variables (such as cardiac output, blood pressure, and heart rate) which can assume an …

The following things about the above distribution function, which are true in general, should be noted. 1. The magnitudes of the jumps at 0, 1, 2 are which are precisely the probabilities in Table 2-2.
