1.Rational number (aka 'fractional') Answer: Numbers that can be
expressed as a fraction
2.Integers Answer: Solid positive and negative numbers
3.Real Numbers Answer: A real number is any number that can be
placed on the number line, whether that be negative or positive,
fraction or decimal.
4.True or False? Any integer is also a whole number. Answer: This
statement is false. An integer can be negative, such as the number
−100-100. −100-100 is not a whole number.
5.Read all the options before answering. −17-17 is... (a. an integer b. a
rational number c. a real number d. all of the above.) Answer: d. all
of the above. −17-17 is an integer, and all integers are also rational
numbers, which in turn are real numbers. 6. set Answer: In
mathematics, a collection of numbers is referred to as a set*
7. Interval Answer: An interval is a set of numbers between two
specified values. An interval can be visualized as a segment of the
number line. The segment of the number line above that falls
between 11 and 22 is called an interval*.
8. Discrete data Answer: Can only have certain, distinct values
Is "counted"
Contains unconnected points
In mathematics, whole numbers, integers, and even integers are all
examples of discrete sets. These sets contain unconnected elements,
with gaps between each value.
In statistics, some data sets will be discrete. Examples of discrete data
sets are the number of adults in a household, the results of rolling two
,dice, and number of machines in operation, as these are distinct
groups.
(Looking at another set of data, consider the number of cars someone
owns. It is not possible to own 3.43.4 cars; you either own three cars or
four. The number of cars someone owns is an example of a discrete
set of data, since the values are distinct, separate, and unconnected.
Positive integers* are an example of discrete data.)
9. Continuous data Answer: Can have any value within an interval Is
"measured"
Does not have clear boundaries between elements or data points
In mathematics, the set of real numbers is an example of a continuous
set. This sets contains continuous elements, with no discernible gaps
between each element. Remember that the number line is a visual
representation of the set of real numbers. Just as the number line is
continuous with no gaps, so is the set of real numbers.
In statistics, some data sets will be continuous. Examples of continuous
data sets are temperature, distance, and time, as the set of possible
values within these groups is continuous. An element in these groups
can hold any real number within a certain interval, dependent upon
the scale used. (A set of data is continuous if it can hold any value
within the set. An example of continuous data might be age. It is
possible to be 22.6722.67 years old. Real numbers are considered
continuous.)
10. 00, 11, 22 is a set of continuous data. True or False? Answer:
False. This statement is false.
00, 11, and 22 are distinct consecutive integers. There are numbers,
such as 1.51.5, between them, so they are not continuous.
11. emperature is an example of continuous data. True or False?
Answer: This statement is
true. Temperature covers an entire interval of data and can be
"measured" rather than counted, so it is continuous.
12. Timesheets log the days that a nurse works each week. Does the
week's timesheet give data that is discrete or continuous? Answer:
, Discrete. The days of the week are discrete and do not allow for
values between them.
13. A graph shows the efficacy of a particular drug at different
dosages. Is
this data discrete or continuous? Answer: Discrete. The graph shows
discrete drug dosages, not all possible dosages, between two
numbers.
14. During a physical, the nurse records the patient's age, weight, and
height. Are these data discrete or continuous? Answer: Continuous.
These are all continuous measurements for which it is possible to
have fractional parts.
15. < Answer: "less than"
16. > Answer: "greater than"
17. Answer: d less than or equal to
18. Answer: e greater than or equal to
19. Which of the following is the correct translation of −3<y<4-
3<y<4? Answer: −3-3 is less
than y which is less than 4 (Both of the << symbols mean "less than,"
so the correct translation is −3-3 is less than y which is less than 4.)
20. How would "w is less than or equal to 9, but greater than or equal
to 5" be
written? Answer: 9we5e (The answer is b. Both symbols mean
"greater than or equal to," so 9ee we59e we5e means "ww is less
than or equal to 99, but greater than or equal to 55.)
21. In math, you may be asked to "evaluate an expression."--what
does that mean? Answer: solve the problem
22. When multiplying a positive number by a negative number, the
product will always be Answer: NEGATIVE
23. Multiplying a negative number by a negative number results in a
Answer: Positive product (The product of two negatives will always
equal a positive.)
