The Gauss-Jordan elimination method different from the Gaussian elimination method in that unlike the Gauss-Jordan approach, which reduces the matrix to a diagonal matrix, the Gauss elimination method reduces the matrix to an upper-triangular matrix.
<h3>
What is the Gauss-Jordan elimination method?</h3>
Gauss-Jordan Elimination is a technique that may be used to discover the inverse of any invertible matrix as well as to resolve systems of linear equations.
It is based on the following three basic row operations that one may apply to a matrix: Two of the rows should be switched around. Multiply a nonzero scalar by one of the rows.

<h2>
Answer: 4</h2>
Step-by-step explanation: 20/5 is 20 divided by 5 which is 4.
20/5=<u>4</u>
<u>4</u>x5=20
5x<u>4</u>=20
So the answer is <u><em>4</em></u>.
Answer:
Subject 's' in terms of 't'
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Given that the subject 't in terms are 's'</em></u>
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
Answer:
And the 90% confidence interval would be between [566.80 and 579.20]
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=22 represent the sample standard deviation
n=36 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.90 or 90%, the significance would be and , and the critical value for this case would be
And replacing we got:
And the 90% confidence interval would be between [566.8033 and 579.1967]
