Negative correlation which is downhill from left to right occurs when one quantity increases while the other quantity decreases.
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
yes
The three different types of correlation are positive correlation (both variables move in the same direction), negative correlation (variables move in opposite directions), and no correlation (variables show no relationship).
Correlation.
that is not a ?
It is not possible to show that since it is not necessarily true.There is absolutely nothing in the information that is given in the question which implies that AB is not invertible.
show that SQUARE MATRIX THE LINEAR DEPENDENCE OF THE ROW VECTOR?
correlation
nope

"If y tends to increase as x increases, then the data have a positive correlation. If y tends to decrease as x increases, then the data have a negative correlation. If the points show no correlation, then the data have approximately no correlation."
For small matrices the simplest way is to show that its determinant is not zero.
The experiment shows that there is a correlation between the two variables, meaning that as one variable changes, the other variable changes in a consistent way. However, it does not necessarily establish a cause-and-effect relationship between the variables. Further analysis is needed to determine causation.
