What can be said about two numbers that have either a positive or negative correlation? No relationship exists. A relationship is not an important part of correlated numbers. A relationship exists and the numbers cause one another. A relationship exists and should be examined.

A relationship exists and the numbers cause one another can be said about two numbers that have either a positive or negative correlation

Option : C

Explanation:

When two numbers have positive correlation, they move in the same direction. If the first variable increases, the second one also increases and if one variable decreases the other one also decreases.If the two numbers have negative correlation, the two numbers move in opposite directions.

A relationship exists between two numbers and the number cause one another. A correlation means that changing one variable affects the other. Correlation among variables need not necessarily imply causation. Positive correlations are mostly used in Finance and stock markets.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
