Timesheets log the days that a nurse works each week. Does the week's timesheet
give data that is discrete or continuous?
Discrete. The days of the week are discrete and do not allow for values between
them.
A graph shows the efficacy of a particular drug at different dosages. Is this data
discrete or continuous?
Discrete. The graph shows discrete drug dosages, not all possible dosages, between
two numbers.
During a physical, the nurse records the patient's age, weight, and height. Are these
data discrete or continuous?
Continuous. These are all continuous measurements for which it is possible to have
fractional parts.

Which of the following is the correct translation of −3<y<4-3<y<4?
−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.)

,How would "w is less than or equal to 9, but greater than or equal to 5" be
written?
9≥w≥5 (The answer is b. Both ≥≥ symbols mean "greater than or equal to," so
9≥w≥59≥w≥5 means "ww is less than or equal to 99, but greater than or equal
to 55.)
In math, you may be asked to "evaluate an expression."--what does that mean?
solve the problem
When multiplying a positive number by a negative number, the product will always
be
NEGATIVE
Multiplying a negative number by a negative number results in a
Positive product (The product of two negatives will always equal a positive.)
Page 3 of 32
, The result of the division of two negative numbers is always
POSITIVE
Zero in multiplication =
The product* of multiplication with zero will always equal zero; whether
multiplying by a positive or a negative, any integer multiplied by zero will result in
zero as the product.
8(superscript 0)
Any non-zero number with an exponent of 0 (or raised to the zero power) equals 1.
