Answer:
(d) mysqldump websites -u root -p > websites_backup.sql
Explanation:
To create a backup mysqldump is used.It is a data backup program.This program was originally written by Igor Romanenko. It creates a backup of file name websites_backup.sql.
So among the given options in the question option d is the correct option which backs up the single database websites in the file website_backup.sql.
For 1.
Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards.
Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.
It's (A)
For 2.
An outlier is a datapoint that's far, FAR away from the others, so it's (B)
For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
Answer:
TACACS+
Explanation:
Terminal Access Controller Access-Control System Plus (TACACS+) is a protocol that provides detailed accounting information and flexible administrative control over the authentication, authorization, and accounting process.
A linear regression model is used to show the relationship between variables on a scatter plot
The equation of the linear regression model is: 
and the correlation coefficient is 0.8034
<h3>How to determine the equation of the
linear regression</h3>
The question is incomplete. So, I will make use of a dataset that has the following calculation summary (from a graphing calculator)
- Sum of X = 45
- Sum of Y = 83
- Mean X = 4.5
- Mean Y = 8.3
- Sum of squares (SSX) = 82.5
- Sum of products (SP) = 128.5
- The value of R is 0.8034.
The equation of the linear regression model is:
