WGU C784 Module 1 Questions with 100% Correct Answers. Whole Number Correct Answer "whole" numbers are numbers whose values are "whole," such as 1 or 2.
Whole numbers only
not negative
not decimal
not fraction
Integers Correct Answer Integers like whole numbers, are numerical figures that do not contain a fractional or decimal component. positive number* or a negative number*.
Whole numbers are positive integers
Rational Number Correct Answer Rational numbers* are numbers that can be expressed as a fraction. This class of numbers includes all integers since any integer can be expressed as a fraction:
.675 is a rational number because it is a decimal whose expansion ends
Fractions Can be integers and whole numbers.
Real Numbers Correct Answer A real number is any number that can be placed on the number line, whether that be negative or positive, fraction or decimal. Real numbers also include decimals that do not end and cannot be written as a fraction.
An example of this is pi
are also whole numbers, integers, and rational numbers
Negative Integer Correct Answer -7, -11, -986581 are examples
Positive Integer Correct Answer 7 is a positive integer
True or False? Any integer is also a whole number Correct Answer False
An integer can be negative, such as the number -100. -100 is not a whole number.
Read all the options before answering. -17 is... a. an integer
b. a rational number c. a real number Correct Answer -17 is an integer, and all integers are also rational numbers, which in turn are real numbers.
According to the strictest definition, 0.07 is... Correct Answer 0.07 is a fully-expressed decimal and therefore a rational number because it can be written as a fraction
π is... Correct Answer π is a real number whose complete decimal expansion goes on forever and does not repeat.
According to the strictest definition, fraction begin. numerator: -1/3 is. Correct Answer According to the strictest definition, fraction begin. numerator: -1denominator: 3fraction end. is a rational number because it can be represented as a fraction.
Relative Value Correct Answer 8>5. Where a number falls on the number line
6 ÷ 0 = undefined Correct Answer when we divide an integer by zero, the answer is always "undefined." Whether positive or negative, an integer divided by zero will deliver an "undefined" result.
Exponents Correct Answer Sometimes called power, it is the number that shows how many times the base is multiplied by itself
4 with an exponent of 5 is displayed as the number '5' directly to the right and above the
number '4'. An exponent can also be denoted with a caret, ^; to the left of the caret is the base number, 4, and to the right of the caret is the exponent, 5. Correct Answer 17^0 = Correct Answer Any number with an exponent of zero equals 1.
Lindsey has 8 pairs of shoes. Every day, Monday thru Friday she wears a pair at random. How many possible combinations of shoes could she wear this week? Correct Answer 8^5. Lindsey has 8 pairs of shoes to choose from This would be considered teh number of possible outcomes of each trial (or picking of shoes at random)
This would mean she has 8^5 possible shoe combinations that she could wear in one week.
A 6-sided die is rolled 5 times. How many possible combinations of outcomes are there after the 5 rolls Correct Answer 6^5
Because it is 6 sides, there are six possible outcomes for each roll
One roll is considered one trial
Since it is being rolled 5 times, the possible outcomes of each roll never change
base number
exponent number Correct Answer base number is the outcome, choices or possibilities
exponent is the trial or how many times you do it
Whole numbers only
not negative
not decimal
not fraction
