|ALREADY GRADED A+

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.

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.

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.

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.

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.

< - ANSWER- "less than"

> - ANSWER- "greater than"

≤ - ANSWER- less than or equal to

≥ - ANSWER- greater than or equal to

Which of the following is the correct translation of −3

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.)

How would "w is less than or equal to 9, but greater than or equal to 5"

be written? - ANSWER- 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? - ANSWER- solve the problem

When multiplying a positive number by a negative number, the product

will always be - ANSWER- NEGATIVE

Multiplying a negative number by a negative number results in a -

ANSWER- Positive product (The product of two negatives will always

equal a positive.)

The result of the division of two negative numbers is always -

ANSWER- POSITIVE

Zero in multiplication = - ANSWER- 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) - ANSWER- Any non-zero number with an exponent of

0 (or raised to the zero power) equals 1.

sampling - ANSWER- The process of selecting research participants

from a population

exponent - ANSWER- sometimes call a power, it is a number that shows

how many times the baseline number is multiplied by itself

probability - ANSWER- the likelihood, or chance, that a certain event

will occur

Order of operations - ANSWER- A set of rules that tells the order in

which to compute.

PEMDAS -- order of operations

(Please excuse my dear aunt sally) - ANSWER- Parentheses, Exponents

& roots, Multiplication, Division, Addition, Subtraction

If a problem only contains multiplication and division they are

considered equal and you work from left to right (same when the

problem only contains addition and subtraction -- work it left to right) -

ANSWER- So: 64 divided 2 * 3 = Work it Left to right 64 divided by 2

= 32 x 3 = 96

A ??? is a positive integer with exactly two positive factors*, 11 and

itself; it cannot be divided evenly by any other two integers. For

example, the only positive numbers that divide 33 are 11 and 33.

Therefore, 33 is a prime number. Prime numbers play an important role

in factoring, which we will explore later in this module. - ANSWERprime number

prime numbers, only 1 and itself like 29 - ANSWER- It is a prime

number. Prime numbers are always odd

Composite number - ANSWER- 15--can divide by 1, 3, 5 so it is

composite

2, 3, 5, 7 are all what type of numbers - ANSWER- Prime
