THE BASICS; what is the vertical axis of a graph called?
A. z-axis
B. x-axis
C. y-axis
D. time-axis - y-axis ;
the vertical axis of a graph is called the y-axis and extends up and down
THE BASICS; what is the name of the horizontal axis of a graph? - x-axis
the horizontal axis of a graph is the x-axis. the x-axis extends side to side.
THE BASICS; how are scores on the ultrasound board exams related to study time? -
directly ;
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), variables are directly related.
Since scores increase as study time increases, these variables are directly related.
THE BASICS; how are caloric intake and weight related? - directly ;
these two terms are directly related. as food intake increases, weight increases. similarly, as food
intake decreases, weight decreases.
THE BASICS; how is weight related to a sonographer's time spent exercising? - inversely
;
two variables are related when changes in one variable result in changes in the other. when the
changes follow in the opposite direction (one increases as at the other decreases), the variables are
inversely related.
THE BASICS; what is the reciprocal of 1,000? - 0.001 ;
,a pair of reciprocal numbers, when multiplied together, have a value of 1. in this case, 1,000 x
0.001 = 1.
THE BASICS; what is the reciprocal of 5? - 1/5 ;
a pair of reciprocal numbers, when multiplied together, have value of 1. in this case, 5 x 1/5 = 1
THE BASICS; what is the reciprocal of 1/10? - 10 ;
a pair of reciprocal numbers, when multiplied together, have value of 1. in this case, 10 x 1/10 = 1
THE BASICS; a sack contains 6 pounds of flour. the contents of the bag are increased by a factor
of 5. how much flour is in the bag? - 30 pounds ;
the term "increase by a factor" means to multiply. 6 x 5 = 30 pounds.
THE BASICS; a bouquet has 30 flowers. the size of the bouquet is decreased by a factor of 3. how
many flowers remain? - 10 ;
the term "decrease by a factor" means to divide. 30/3 = 10.
THE BASICS; which of the following is not a measure of area?
A. square cm
B. meters squared
C. cubic meters
D. feet x feet - cubic meters ;
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^2, or square miles
THE BASICS; a sonographer measures the perimeter of an anatomical structure. which of the
following choices is a reasonable value for the measurement?
,A. 6 cm^2
B. 5 cc
C. 15 mm
D. 18 dB - 15 mm
"perimeter" means the length of the outer boundary of a structure. for example, a square with an
edge that is 5 inches long will have a perimeter measuring 20 inches (four sides, each with a length
of 5 inches).
THE BASICS; what are the units associated with the circumference of a circle? - mm ;
the circumference of a circle is the length of the circle's outer boundary and is measured in units
of length
THE BASICS; the volume of a cystic structure is estimated from sonographic data. which of the
following is an acceptable measurement of this volume?
A. 6
B. 6 cm
C. 6 cm^2
D. 6 cm^3 - 6 cm^3
the units of volume are length cubes, such as ft^3 or cubic centimeters. volume may also be
expressed as length to the third power.
THE BASICS; the speed of the red blood cells traveling through a blood vessel is 750 cm/sec. you
are asked to measure this speed in miles per hour. what information would be sufficient for you to
complete your task? - how many seconds per hour and the number of miles in a centimeter;
To convert one unit to another requires a
factor that relates the two terms. For
example, to change a measurement of
length from feet into inches, we must know. now many inches are in a foot. In this case We are
asked to convert cm per sec into miles per hour. Therefore, we require two pieces of information:
the relationship between seconds and hours (relating one Unit of time to another) and the
, relationship between miles and centimeters (relating one unit of distance to another). When units
are changed, the actual amount does not change. For example, ten dimes provide the same
purchasing power as four quarters. The units may be different, but the "total picture" remains the
same.
THE BASICS; how much bigger is one billion than one thousand? - 1,000,000 times ;
a billion is one million times larger than a thousand. a million is 1,000,000.
THE METRIC SYSTEM; Select the sequence that appears in increasing order.
A. mega, kilo, hecto, milli, gigi
B. nano, milli, micro, deci, deca, mega
C. centi, deci, deca, hecto
D. milli, hecto, centi, deci, nano, gigi - centi, deci, deca, hecto;
centi means "one-hundredth", deci means "one tenth", deca means "ten", and hecto means
"hundred". this sequence is increasing, starting from the smallest and ending with the largest.
THE METRIC SYSTEM; How many nanoseconds are in 7 seconds? - 7,000,000,000 ;
nano means billionth. there are one billion billionths in one second. therefore, there are seven
billion billionths in seven seconds.
THE METRIC SYSTEM; the letters below represent the abbreviations for the prefixes of the
metric system. select the sequence that appears in decreasing order.
A. m, k, M, g, da
B. a, m, k, d, u
C. g, k, di, m, u, n
D. M, k, da, d, c - M, k, da, d, c ;
THE BASICS; what is the vertical axis of a graph called?
A. z-axis
