B)2,644.22
C)6,874.14
D)None of the above

Accepted Answer

The value of the given arithmetic expression is 4,540.67.
Use the order of operations to solve the expression:
1. Parentheses: 119 - 558 / (87.6 - 56.6) x 235 + 6,755.22
= 119 - 558 / (31) x 235 + 6,755.22
2. Division and multiplication, left to right: 119 - 558 / 31 x 235 + 6,755.22
= 119 - 18 x 235 + 6,755.22
= 119 - 4230 + 6,755.22
4. Subtraction and addition, left to right: 119 - 4230 + 6,755.22
= -4,111 + 6,755.22
= 2,644.22

Question 4

A)2,253.4
B)3,088.8
C)8,891.5
D)None of the above

Accepted Answer

The value of the given arithmetic expression is 2,253.4.
Solution
Use the order of operations to solve the expression.
1. Parenthesis: 323 + 543 x (45.3 + 33.6) / 22 -17
= 323 + 543 x 78.9 / 22 -17
2. Multiplication: 323 + 543 x 78.9 / 22 -17
= 323 + 42,842.7 / 22 -17
3. Division: 323 + 42,842.7 / 22 -17
= 323 + 1,947.4 -17
4. Addition: 323 + 1,947.4 -17
= 2,270.4 - 17
5. Subtraction: 2,270.4 - 17
= 2,253.4

Question 5

A)Answer specific questions about the data contained within a spreadsheet.
B)Graphically display variations between data within a given data set.
C)Apply specific rules to data meeting defined criteria.
D)All of the above

Accepted Answer

The conditional formatting command allows a spreadsheet user to perform all of the tasks listed above. Conditional formatting commands are available in most spreadsheet programs, including Microsoft Excel and Macintosh Numbers. Additionally, the conditional formatting command is useful in detecting critical issues and analyzing trends.

Question 6

Fill in the blank: The given expressions are examples of _______ statements. If < Condition> Then If (point_score> =) then writeln ('bad data') If (< C1> ) then begin if (< C2> ) then {< A> } and end else {< B> } A)Parenthetical B)Alternate C)Optional D)Decision

Accepted Answer

The given expressions are examples of decision statements. Decision statements allow a computer to execute commands associated with statements such as If and If-then-Else. These statements enable the development of computer applications to assist in planning, diagnostics, and developing detailed reporting systems.

Question 7

Which of the following pieces of computer hardware is responsible for rendering images on a computer's monitor or display screen?
A)Graphics card
B)Mother board
C)Memory card
D)None of the above

Accepted Answer

A graphics card is responsible for rendering images on a computer's monitor or display screen. A graphics card processes and converts information from a computer's central processing unit into pixels that can be displayed on a monitor. Upgraded graphics cards with faster speed and improved performance are sometimes needed to support programs that run videos and 3-D graphics.

Question 8

The term "schema," as related to the operations of a geographic information system (GIS), refers to which of the following?
A)A set of definitions for tables, fields and the relationships between fields and tables in a relational database, as well as standards for grouping objects in the database.
B)A list of resources used in developing feature classes and shape files.
C)A and B
D)None of the above

Accepted Answer

As related to a GIS, the term schema refers to data dictionaries that provide a logical classification of the objects stored, viewed, indexed, and verified within a database.
Schemas serve as a guidance document so that the developers of the GIS can ensure consistency when entering georeferenced data and that end users understand the specifics of the data analyzed.

Question 9

A relational database is one in which:
A)Genealogical information is stored.
B)Collections of tables are associated to each other by shared fields.
C)Personal information is uploaded for use by an online dating service.
D)None of the above

Accepted Answer

A relational database is one in which collections of tables are associated to each other by shared fields.
Relational databases are used for organizing complex information in GIS systems to link geographic/spatial information such as maps and imagery to associated attribute information included in tables and reports. The georeferenced data are linked in a manner so that information can be extracted from the database by requests based on the physical location or characteristics of the data features.

Question 10

As a rule of thumb, horizontal utility line information housed in geographic information systems utilized by most city governments is assumed to be accurate to what measure?
A)1 mm
B)1 inch
C)3 inches
D)3 feet

Accepted Answer

As a rule of thumb, the horizontal utility line information stored in GIS systems developed by a typical city government is assumed to accurate to the 3-foot level. Because the availability and accuracy of older infrastructure as-built drawings may be questionable, many city governments have digitized utility lines from attributes identified on aerial photography.
So before you dig up the sewer lateral in your front yard that is shown on your property's GIS mapping, make sure to find out from your sewer utility how the location of your lateral was georeferenced!

Question 11

What type of attribute domain defines a set of permissible values for an attribute stored in a geodatabase?
A)Commercial
B)Network
C)Coded Value
D)All of the above

Accepted Answer

A Coded Value domain defines a set of permissible values for an attribute stored in a geodatabase. Coded value domains consist of a code and an equivalent value. For example, the numbers 1, 2, or 3 may correspond to sanitary, stormwater, or combined types of manholes in a sewer manhole feature class.

Question 12

Which of the following are examples of roadway attributes that may be stored in a geographic information system?
A)Roadway type (interstate, local highway, street, etc.)
B)Pavement type (asphalt, concrete, composite, etc.)
C)Location of entry points to the roadway
D)A and B

Accepted Answer

Examples of roadway attributes that may be stored in a geographic information system include roadway and pavement types.
Attributes comprise relevant, nonspatial information related to a geographic feature such as a roadway that is stored in a table and linked to the feature by a unique identifier.

Question 13

What is the name of the function that can be used by a geographic information system to perform a network analysis on a geometric network?
A)Cost-benefit analysis
B)Zonal analysis
C)Network trace
D)None of the above

Accepted Answer

A network trace can be used to perform a network analysis on a geometric network stored in a geographic information system.
Network traces can be used to find geographic features that are connected physically, have common ancestors, are looped, or have upstream or downstream components. For example, a network trace conducted on a waterline feature class can be used to depict properties within a service area that are downstream of a specific booster station.

Question 14

A geographic coordinate system definition includes which of the following:
A)Datum
B)Prime meridian
C)Angular unit
D)All of the above

Accepted Answer

A geographic coordinate system definition consists of a datum, prime meridian, and angular unit.
A geographic coordinate system is a reference system that utilizes latitudes and longitudes to define the location of points on a surface of a sphere or spheroid.
