Exam Review (Latest 2025/ 2026Update) |
Questions and Verified Answers| 100%
Correct| Grade A
Discrete data - answers Distinct values, counted, unconnected points
Number of eggs
Continuous data - answers Values within a range, measured, connected points
Height of a child
Less than/greater than - answers ( ) in writing, open circle on line, number NOT
included
Less than or equal to/greater than or equal to - answers [ ], closed circle on line, number
included
Prime numbers - answers Only 2 positive factors
Composite number - answers More than 2 positive factors
Prime factorization - answers Writing number as a product of only prime numbers
greatest common factor (GCF) - answers The largest factor that two or more numbers
have in common.
multiples of a number - answers A number multiplied by various integers
3: 3,6,9,13,15,etc
least common multiple - answers Smallest positive number that can be divided evenly
milli - answers thousandth
kilo - answers thousand
Celsius to Fahrenheit - answers (C x 9/5) + 32
Farenheit to Celsius - answers 5/9 x (F - 32)
like terms - answers same variable and same exponent, combined by addition and
subtraction
, Additional/subtraction principle of equality - answers Adding/subtracting the same
number to both sides causes the resulting expression to remain the same
Multiplication/division principle of equality - answers Multiplying/dividing by the same
nonzero number on both zeros doesn't change the resulting expression
Butterfly method / cross multiply - answers A/b=c/d then AxD=BxC
slope intercept form of a line - answers y=mx + b (m is the slope, b is the y intercept
point)
Slope of a line - answers Two points (x1,y1) and (x2, y2) the slope goes through
Rise: (y2-y1)/(x2-x1)
positive slope - answers Up to the right
negative slope - answers Down to the right
Inequalities - answers If multiplying or dividing by a negative number, arrow direction
must be switched
A number that can be written as a ratio of integers, which means it can be written as a
fraction. - answers rational number
The result of multiplying values. - answers product
A number whose value is 0 or greater and can be represented without a fractional or a
decimal component. - answers whole number
The property that 0 can be added to any number without changing the value of the
number. Likewise, 1 can be multiplied by any number without changing the value of that
number. - answers identity property
The property that under certain operations in a multi-step expression, the computations
may be done in any order. Commonly represented as (a + b) + c = a + (b + c). Addition
and multiplication both have this property, but subtraction and division do not. - answers
associative property
The product of any integer with itself yields this. So, a number is this if it can be written
as the square of an integer. For example, 9 is this because 3 * 3 = 9. Other examples
are 16, 25, 36, 49,... - answers perfect square
In mathematics: a collection of numbers. - answers set
A set of rules that defines the order in which mathematical operations should be
performed - answers order of operations
