It is a positive relationship.
direct variation or positive correlation.
The other can increase, decrease or stay the same. It depends on the relationship between the two variables.
An arithmetic sequence does not have a constant rate of increase or decrease between successive terms, so it cannot be called anything!The constant increase or decrease is called the common difference.
If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.
There is quite a high degree of linear agreement between the two variables with one showing an increase when the other shows a decrease.
Direct variation
Variation in direct proportion.
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
when ductility increase hardness decrease
direct variation or positive correlation.
by their increase or decrease
They are inverly related ,number increase cost decrease as wellas cost increase may qulity & number decrease
Immediately after an increase in temperature, the relationship between two variables may change. This change could result in an increase, decrease, or no change in their relationship, depending on the specific properties of the variables involved.
According to Boyle's Law of Pressure-Volume Relationship, an increase in the pressure of a gas will decrease it's volume. And according to Charles's Law of Temperature-Pressure Relationship, an increase in pressure causes an increase in temperature.
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
A relationship between two variables in which the data do not increase or decrease together at the same rate is known as a non-linear relationship. In this type of relationship, the rate of change between the variables can vary, leading to a situation where one variable may change significantly while the other changes little, or vice versa. This can often be represented by a curve rather than a straight line on a graph. Non-linear relationships are common in many real-world scenarios, such as in economics or biology.
