Slope: 3/2 (the coefficient of x)
Y-Intercept: (0,3) (substituting x = 0 into the equation)
Ans: Yellow
These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.

Answer: 0.3679
Step-by-step explanation:
The cumulative distribution function for exponential distribution is :-
, where is the mean of the distribution.
Given : A mean length of waiting time equal minutes
i.e. Mean number of calls answered in a minute
Now, the proportion of callers is put on hold longer than 2.8 minutes is given by :_
Hence, the proportion of callers is put on hold longer than 2.8 minutes = 0.3679
