• How are scores on the ultrasound board
exams related to study time?
A. inversely
B. conversely
C. directly
D. unrelated -✓✓C.
Two variables are related when changes in
one variable result in changes in the other.
When the changes go in the same direction
(both increase or both decrease), the
variables are directly related. Since scores
increase as study time increases, these
variables are directly related.

area?
A. square cm
B. meters squared
C. cubic meters
D. feet × feet -✓✓C. Cubic meters are not used to measure
area; they are used to measure volume. An
area is measured in units of distance
squared. For example, a rectangle's area is
its length multiplied by its width, and can be
reported in square feet, in?, or square
miles.
• 12. A sonographer measures the perimeter of
an anatomical structure. Which of the
following choices is a reasonable value for
the measurement?
