Event - Solution an outcome, or set of outcomes, whose chance of occurrence can be represented with a probability. Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when adding together only the whole numbers? A. 5.
B. 11
C. 12.
D. 15 - Solution D. 15 Operation - Solution In Mathematics, an operation is a procedure which generates a new value from one or more operands, or Mathematical values. Conditional Proportion - Solution A proportion where one part of the proportion is a variable, or unknown quantity. Coefficients - Solution A number by which a number is multiplied. This number is written in front of the variable(s). Mean - Solution Average, calculated by adding a series of elements in a data set together and dividing by the total number in the series. Outlier - Solution An observation point that is statistically distant from the other observations in the dataset. Regression Line - Solution The line of best fit to show the relationship between variables, the one that minimizes distance from each data point to the line. Experiment - Solution A procedure that can be done repeatedly which has a well-defined set of outcomes. Given the following expression: 4 + 7 × (6 - 3)2. What is the answer using proper order of operations? A. 25 B. 46 C. 67 D. 99 - Solution C. 67 Multi-Step Expression - Solution an expression or equation with more than two values and two or more operators that requires multiple steps to be solved. Improper Fraction - Solution A fraction where the number in the numerator is more than the number in the denominator.
What is the greatest common factor of 132 and the square root of 121 using prime factorization? A. 1 B. 2 C. 10 D. 11 - Solution D. 11 Continuous - Solution A collection of numbers whose values are not dividable into distinct values. Proper Fraction - Solution A fraction where the number in the numerator is less than the number in the denominator. Unlike Terms - Solution Terms that do not have the same variable(s) with the same exponent(s). These terms cannot be combined using addition or subtraction. Valid Data - Solution Data that results from a test that accurately measures what it was intended to measure. Five-Number Summary - Solution The minimum, first quartile, median, third quartile, and the maximum. A box plot represents the five numbers in a five-number summary. Observational Study - Solution The researcher observes if there is an association between variables. There is no treatment or control group. Conditional Probability - Solution A probability that depends on the occurrence of an earlier event. What is the greatest common factor of 24 and 84 using prime factorization? A. 2 B. 4 C. 8 D. 12 - Solution D. 12 Negative Number - Solution A number whose value is less than zero. On the number line, negative numbers are to the left of zero.
Numerator - Solution The number that is written before the slash, or above the fraction bar, in a fraction. Slope - Solution The number that describes the direction and steepness of a line drawn on the coordinate plane. It is measured by 'rise over run'. Rise/Run = (the change in y value) / (the change in x value) = (y2-y1)/(x2- x1). Statistics - Solution The science that deals with the interpretation of numerical facts or data through theories of probability. Also, the numerical facts or data themselves. Conditional Percentages - Solution A way to approximate a percentage by dividing the number of times an event occurred in an experiment by the total number of respondents in that row or column. See Relative Frequency. Hypothesis Test - Solution A statistical test that tells us whether a result is significant. Disjoint - Solution Two events which both cannot occur at the same time. What is 3/14 - 1/7? A. 1/ B. 2/ C. 5/ D. 3/2 - Solution A. 1/ Whole Number - Solution A number whose value is 0 or greater (negative number are not considered whole numbers) and can be represented without a fractional or decimal component. Cross Multiplying - Solution A method used to prove that a proportion is true. Addition Principle of Equality - Solution The fact that we can add the same number to both sides of an equation, and the result will be an equivalent equation.
A patient's protein intake for today has been 15.76g, 8.49g, and 22.58g. What is the total protein intake rounded to the nearest tenth of a decimal? A. 46.5g B. 46.8g C. 46.9g D. 47g - Solution B. 46.8g Square Root - Solution A number that produces a specified number when it is multiplied by itself. Rounding - Solution A method of estimating in order to make working with a number easier. Term - Solution In Mathematics, a term is an individual number or variable, or numbers and variables multiplied together in an expression. Terms are separated by addition or subtraction signs. Stem Plot - Solution A visual representation of data in which individual points are plotted to the right of a vertical line, or chart, and the left (the "stem") shows the interval categories. Scatterplot - Solution A graph that uses dots on a coordinate plane to show the relationship between two quantitative variables. Population - Solution An entire pool from which a sample is drawn. Multiplication Rule for Independent Events - Solution If two events are independent, then P(A and B) = P(A) x P(B). Given the equation: (.5475 - .3025) x .15. What is the solution rounded to the nearest thousandth? A.. B.. C.. D. .037 - Solution D.. Rational Number - Solution A rational number is a number that can be written as a ratio of integers, which means it can be written as a fraction. Percent Sign - Solution A symbol used to denote percentages.
Horizontal Line - Solution A line that runs left to right on the coordinate plane, parallel to the x-axis. It has no 'rise' or change in y-value. Interquartile Range - Solution The difference, in value, between the bottom and top 25 percent of the sample or population. Box Plot - Solution A graphical rendering of the range and the first and third quartiles of a data set with the data set's median in the center. Control Group - Solution In an experimental study, this group does not receive treatment or receives a placebo. Venn Diagram - Solution A type of chart that illustrates distinct sets, topics, or objects relate to one another. Uses circles to represent events. An intravenous drip is infused at a rate of 4.5 milliliters per minute. How many milliliters are infused per hour? A. .075mL B. 2.7mL C. 75mL D. 270mL - Solution D. 270mL Base Number - Solution The number multiplied by itself when paired with an exponent. For example, in 8 to the third power (8^3), 8 would be the base number. Trailing Zeros - Solution Sequence of zeros after the last non-zero digit in a decimal number. Equation - Solution Two Mathematical expressions separated by the equals sign, =. The two expressions on either side of the equals sign hold the same value as one another. Bar Chart - Solution A graph that displays data that is distributed over groups or categories. Relative Frequency - Solution A way to approximate a percentage by dividing the number of times an event occurred in an experiment by the total number of trials.

C. 77°
D. 80° - Solution C. 77° Multiplicative Inverse - Solution The multiplicative inverse of a number x is the number you must multiply x by to get 1. For example, 5 and 1/5 are multiplicative inverses. Terminal Decimal - Solution A decimal number that has a finite number of digits. Slope-Intercept Form - Solution A common format that a linear equation can take that is helpful for graphing purposes. It is of the form y = mx + b, where m is the slope of the line and b is the y-intercept.
