The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1
<h3>What is the Correct Scale Calibration?</h3>
We are told that a certain scale is not calibrated correctly,
Mass displayed = 0.75 kg (less than its actual mass).
The scale of display = 1
Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.
Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.

Answer:
the answer should appear in a paragraph format
A statement which best illustrates the relationship between entities and attributes is: B) the entity CUSTOMER with the attribute PURCHASE.
<h3>What is an entity relationship?</h3>
An entity relationship can be defined as a data model with the highest level of abstraction and it is typically designed and develop to avail designers or programmers (end users) an ability to use a graphical tool to examine structures rather than describe them by using text.
<h3>What is an attribute?</h3>
In Computer technology, an attribute can be defined as a unique characteristic or quality which primarily describes an entity in a software program.
In this context, we can infer and logically deduce that a statement which best illustrates or shows the relationship between entities and attributes is the entity "CUSTOMER" with the attribute "PURCHASE."

Answer:
Explanation:
All but kg can be vector quantities.
m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.
meters can be a vector or the unit of a vector. It is called displacement when it has direction.
km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail. hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.
kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.
