GED Math Terms Advanced Test Questions And Correct Detailed Answers.

consecutive numbers - correct answer numbers in counting order Data - correct answer a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things Dot plot - correct answer a graphical display of data using dots Function - correct answer a special relationship where each input has a single output. It is often written as "f(x)" where x is the input value Graph - correct answer a diagram that shows a relationship among numbers Histogram - correct answer a graphical representation of the distribution of numerical data Mean - correct answer a measurement of average; the sum of a set of numbers divided by the number of numbers in a set Median - correct answer a measurement of average; a number in the middle of a set of numbers, or the mean of the two middle numbers in a set Mode - correct answer a measurement of average; the number that occurs most often in a data set. Example: in the set {1,5,7,5,9}, the mode is 5 because there are 2 fives and only one of each of the others. Permutation - correct answer relates to the act of rearranging, or permuting, all the members of a set into some sequence or order (unlike combinations, which are selections of some members of the set where order is disregarded) Probability - correct answer the chance of an event happening, usually expressed as the ratio of the number of favorable outcomes to the total number of outcomes Proportion - correct answer a statement that two ratios (or fractions) are equal Scientific notation - correct answer a number written as the product of a number between 1 and 10 and a power of 10 Unit rate - correct answer describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Some common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc. Ratio - correct answer comparison between two numbers. Separated by a colon (:), the word "to", or may be written in fraction form. Cross Products - correct answer The product of the numbers which are diagonal from one another in a proportion equation. Should be equal on both sides. Common denominator - correct answer for a set of fractions, a number into which each denominator can divide evenly Denominator - correct answer the bottom number in a fraction Difference - correct answer the answer to a subtraction problem Equation - correct answer a statement that two amounts are equal Estimate - correct answer as a noun: an approximate value. as a verb: to find an approximate value. Fraction - correct answer a part of a whole Greatest common factor - correct answer the greatest factor that divides two numbers Improper fraction - correct answer a fraction in which the numerator is greater than or equal to the denominator Least common multiple - correct answer the smallest positive number that is a multiple of two or more numbers. Example: the Least Common Multiple of 3 and 5 is 15, because 15 is a multiple of 3 and also a multiple of 5. Other common multiples include 30 and 45, etc, but they are not the smallest (least). Mixed number - correct answer a number with both a whole number and a fraction Numerator - correct answer the top number in a fraction Product - correct answer the answer to a multiplication problem Proper fraction - correct answer a fraction in which the numerator is less than the denominator Sum - correct answer the answer to an addition problem Coordinate plane - correct answer a flat surface divided by a horizontal x-axis and a vertical y-axis Coordinates / ordered pair - correct answer a pair of numbers in the form (x,y) that identify the distance of a point from the origin or center on the coordinate plane. The first number tells the distance to the left or right of the vertical axis, and the second number tells the distance above or below the horizontal axis Cube - correct answer a number multiplied by itself three times (2^3, or 2 x 2 x 2 = 8) Cube root - correct answer the opposite of the cube of a number; a square root, but to the 3rd power, rather than the 2nd. (the cube root of 8 is 2, because 2 x 2 x 2 = 8) Distributive property of multiplication - correct answer when multiplying a number by a sum or a difference, you may first multiply each number in the sum or difference, or you can find the sum or difference and then multiple. For any numbers a, b, and c, a(b+c) = ab+bc and a(b-c) = ab-ac. Evaluate - correct answer to find the value of a numerical or algebraic expression; to solve an equation Exponent - correct answer a number that tells the power to which a base is raised. For example, in 3^2, the base is 3 and the exponent is 2. Factor - correct answer as a noun: a number that divides evenly into another number as a verb: to write a number or an algebraic expression as a product of two or more terms Inequality - correct answer a statement that two amount are not equal. For example, (less than) or (greater than) Linear equation - correct answer an equation whose graph is a straight line Quadratic equation - correct answer an equation in which at least one variable is raised to the second power Square root - correct answer one of two equal factors of a number Unknown OR Variable - correct answer a symbol, usually a letter, that represents an unknown value Area - correct answer a measure of the amount of surface on a closed plane figure Circle - correct answer a plane figure, each point of which is the same distance from the center Circumference - correct answer the distance around a circle Cone - correct answer a 3-dimensional figure whose base is a circle and whose height is the perpendicular distance from the base to the vertex Congruent figures - correct answer geometric figures with exactly the same shape and same size Cylinder - correct answer a 3-dimensional figure that has both a circular base and a circular top, and whose height is the perpendicular distance from the top to the bottom Diameter - correct answer the distance across and through the center of a circle Hypotenuse - correct answer in a right triangle, the side opposite (across from) the right angle Legs - correct answer the two shorter sides in a right triangle Line - correct answer a straight path of points that continues in two opposite directions Line segment - correct answer a straight path of points with definite length, having two endpoints.
