For all real numbers a( b + c ) = ab + ac a( b - c ) = ab - ac
Two or more terms that have the same variable(s) with the same power(s)
a process for converting measures into different units by using unit multipliers
Area of a square
A = s²
Area of a rectangle
A = lw
Area of a parallelogram
A = bh
Area of a circle
A = πr²
Area of a triangle
A = ½bh
Square Root √x
The number multiplied by itself to give x
A number that is a square of an integer.
A measure of how likely a given event, or outcome, will occur. Represented by a fraction, decimal, or percent. (# ways to get what you want)/(Total # of possibilities)
Solve an equation
To find the value or values of a variable which will make the statement true. There is always a possibility of no solution or all numbers are a solution.
Operations that undo each other. Addition ↔ Subtraction Multiplication ↔ Division
The variable whose value can be chosen. INPUT
The variable whose value is determined by the input value of another variable. OUTPUT
A display where the data is organized by PLACE VALUE, very useful if you need to find the mean, median, or mode of the data set.
A display where the data is represented by vertical or horizontal bars.
The average of a set of numbers. The sum of values in a data set divided by the number of data values.
The middle number in a set of numbers when they are arranged in order. If there is an even number of data values in the set, find the mean of the two middle numbers.
The value or values that occur most frequently in a data set. If all values occur the same number of times, then it does not exist.
The set of possible values for the independent variable. The x values.
The set of possible values for the dependent variable. The y values.
A point on the coordinate plane (x,y)
A set of ordered pairs where each number in the domain is matched to one or more numbers in the range.
A special relation where every x value in the domain pairs with exactly one value in the range (y).
f(x) This is read as "f of x" This does NOT mean f times x. This is a special way to show an expression is a function. It can use other letters but must have the same format where (?) is the independent variable. A(l) G(e) B(r)
