Question

Which expression creates the value shown in ID?

State
$ 3 Region
$ 6 Area
$ 3 ID
$ 14
58 0040 11 58-0040-11
a. ID=catx(State,Region,Area,'-');
b. ID=cat(State,Region,Area);
c. ID=cats(State,Region,Area);
d. ID=catx('-',State,Region,Area);

Answer 1

The correct expression to generate the ID '1458-0040-11' using State, Region, and Area with hyphens is 'ID=catx('-',State,Region,Area);', which corresponds to option (d).

Step-by-step explanation:

The question refers to creating a string that represents an identification number (ID) using concatenation functions in a programming language, such as SAS. The ID is composed of elements for State, Region, and Area, separated by hyphens. To achieve the result of '1458-0040-11', where these elements are joined by hyphens, the correct expression is:

ID=catx('-',State,Region,Area);

This means the correct answer to the question is option (d) because catx is a function that concatenates strings with a specified delimiter, in this case a hyphen.
