absolute value - correct answer the distance a number is from zero on a number line example: I-4I binomial - correct answer a polynomial with two terms example: 5x3+4x or 2x-7 coefficient - correct answer number that appears in front of a variable and is multiplied by that variable example: 5x-4y+z (5, 4) constant - correct answer a term that is unchanging; either has no variables or variables that cancel out example: 15 or 2x+7-2x ( 15, 2 and 7) data - correct answer collected facts and information used to analyze a situation decimal points - correct answer the symbol that shows the separation between a whole number and a portion or part of a whole number example: .75 degree - correct answer also a unit of measure in an angle example: 45° denominator - correct answer the number on the bottom of a fraction- identifies the number of parts in the whole example: 3/4 (means there are 4 parts in the whole) difference - correct answer the answer to a subtraction problem distribution - correct answer data showing the frequency of an occurrence dividend - correct answer the amount that is being divided divisor - correct answer a number that divides into another number evenly, also known as a factor exponent - correct answer the number written above the base that tells how many times the base is multiplied by itself example: 7² fraction - correct answer portion of a whole number that has a numerator (top number) and denominator (bottom number); has an equivalent decimal and percentage inequality - correct answer a statement that relates unequal terms example: 6≠4+3 interest - correct answer an amount of money that is paid or earned and is calculated over time inverse - correct answer opposite or reverse of mean - correct answer measure of central tendency; the average number in a set of data found by adding all numbers in the data set and dividing by the number of values given example: for the data set 3, 4, 5, 6 add the numbers 3+4+5+6=18 divide the answer by the number of numbers added- 18÷4=4.5 median - correct answer measure of central tendency; middle number in a set of data, if there are two middle numbers (in an even set) add those 2 numbers, then divide by 2 mixed number - correct answer a number made up a whole number and a fraction example: 5 1/4 read five and one-fourth mode - correct answer measure of central tendency; the number that appears the most in a data set monomial - correct answer polynomial with only one term example: 4xy number line - correct answer a way to picture the order of numbers; goes from smallest number on the left (can be negative) to largest number on the right numerator - correct answer the top number of a fraction that tells how many parts of a whole are being considered example: 5/8 means five parts out of eight ordered pair - correct answer a pair of numbers that indicate a point on a grid; the first coordinate is on the x-axis and the second on the y-axis example: (1,3) 1 is x-coordinate, 3 is y-coordinate pattern - correct answer a series whose order is predictable and repeating example: 2, 4, 6, 8, 10....the next numbers in the series are 12, 14, 16 percent - correct answer out of 100 example: 32% of the profit is from books, so $32 out of every $100 is from books sold polynomial - correct answer an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables example: x² − 4x + 7 principal - correct answer original amount borrowed or deposited separate from interest example: before 2.5% interest is charged, the original amount of a personal loan is $5,000 product - correct answer the answer to a multiplication problem proportion - correct answer a relationship that compares two values example: 1/3 = 2/6 (when you cross multiply, the products are the same on both sides) range - correct answer measure of central tendency; the difference between the highest and lowest values in a set of data example: 1, 3, 5, 6, 8 (subtract 1 [lowest number] from 8 [highest number], the answer is 7 ratio - correct answer compares two numbers by using fractions or colons example: for every 1 sunny day, there are 4 days of rain 1:4 or 1/4 slope - correct answer measurement of the steepness of a line; y=mx+b sum - correct answer answer to an addition problem trinomial - correct answer polynomial with three terms connected by + or - variables - correct answer letters that represent unknown numbers example: 7x=14 x is unknown until the equation is solved
