Infections are a cause of encephalopathy. Many types of bacteria, viruses, and fungi can cause encephalitis by infection and inflammation of the brain tissue or of the meninges (meningitis) that line the brain and spinal cord.
A value of zero indicates that there is no relationship between the two variables. If the correlation coefficient of two variables is zero, it signifies that there is no linear relationship between the variables. However, this is only for a linear relationship; it is possible that the variables have a strong curvilinear relationship.
This polynomial has three terms, including a fourth-degree term, a second-degree term, and a first-degree term. There is no constant term. This is a fourth-degree polynomial. When a term contains both a number and a variable part, the number part is called the coefficient.DVERTISEMENT. Any term that doesn't have a variable in it is called a constant term because, no matter what value you may put in for the variable x, that constant term will never change. In the picture above, no matter what x might be, 7 will always be just 7.
