Answer:  The required expression is n-3.

Step-by-step explanation:  We are given to write an expression for the following statement :

"n decreased by 3."

We know that

if we are decreasing a units from some quantity b, then we should subtract a from b.

This is written as follows :

E=b-a.

Therefore, for the given expression, we should subtract 3 from n.

This can be written as :

E=n-3.

Thus, the required expression is n-3.

lana66690 [7]

A circle has a center, radius, diameter and points in a plane. Depending on the context, the definition of a circle must contain at least one of the following terms:

Center

Radius

Diameter

Points in a plane

The complete question is as follows:-

James defines a circle as "the set of all the points equidistant from a given point." His statement is not precise enough

because he should specify that

A circle includes its diameter

The set of points is in a plane

A circle includes its radius

The set of points is collinear

<h3>What is a circle?</h3>

A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.

Based on James' definition of a circle, he needed to specify that the points are in a plane (option c).

As presented in his definition "the set of all the points" can be interpreted in several ways. Some of which are:

the set of points on a line

the set of points in a plane

the set of points in a region

Etc

Of these numerous possible interpretations, James should have specified that the set of points is in a plane
