What is the sum when adding together only the whole numbers? A. 5. B. 11 C. 12.
D. 15 - PRECISE ANSWER D. 15
Operation - PRECISE ANSWER In Mathematics, an operation is a procedure which generates a new value from one or more operands, or Mathematical values.

This number is written in front of the variable(s). Mean - PRECISE ANSWER Average, calculated by adding a series of elements in a data set together and dividing by the total number in the series. Outlier - PRECISE ANSWER An observation point that is statistically distant from the other observations in the dataset. Regression Line - PRECISE ANSWER The line of best fit to show the relationship between variables, the one that minimizes distance from each data point to the line. Experiment - PRECISE ANSWER 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 - PRECISE ANSWER C. 67 Multi-Step Expression - PRECISE ANSWER An expression or equation with more than two values and two or more operators that requires multiple steps to be solved. Improper Fraction - PRECISE ANSWER A fraction where the number in the numerator is more than the number in the denominator.
Fair - PRECISE ANSWER An experiment in which all outcomes are equally likely. 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 - PRECISE ANSWER D. 11 Continuous - PRECISE ANSWER A collection of numbers whose values are not dividable into distinct values. Proper Fraction - PRECISE ANSWER A fraction where the number in the numerator is less than the number in the denominator. Unlike Terms - PRECISE ANSWER Terms that do not have the same variable(s) with the same exponent(s). These terms can not be combined using addition or subtraction. Valid Data - PRECISE ANSWER Data that results from a test that accurately measures what it was intended to measure. Five-Number Summary - PRECISE ANSWER The minimum, first quartile, median, third quartile, and the maximum. A box plot represents the five numbers in a five-number summary. Observational Study - PRECISE ANSWER The researcher observes if there is an association between variables. There is no treatment or control group. Conditional Probability - PRECISE ANSWER 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 - PRECISE ANSWER D. 12
Negative Number - PRECISE ANSWER A number whose value is less than zero. On the number line, negative numbers are to the left of zero. Numerator - PRECISE ANSWER The number that is written before the slash, or above the fraction bar, in a fraction. Slope - PRECISE ANSWER 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 - PRECISE ANSWER 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 - PRECISE ANSWER 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 - PRECISE ANSWER A statistical test that tells us whether a result is significant. Disjoint - PRECISE ANSWER 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 - PRECISE ANSWER A. 1/ Whole Number - PRECISE ANSWER 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 - PRECISE ANSWER A method used to prove that a proportion is true.
Linear Interpolation - PRECISE ANSWER Estimation using the linear regression equation in between known data points. Sample Space - PRECISE ANSWER The entire set of outcomes for a trial or experiment. 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 - PRECISE ANSWER B. 46.8g Square Root - PRECISE ANSWER A number that produces a specified number when it is multiplied by itself. Rounding - PRECISE ANSWER A method of estimating in order to make working with a number easier. Term - PRECISE ANSWER 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 - PRECISE ANSWER 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 - PRECISE ANSWER A graph that uses dots on a coordinate plane to show the relationship between two quantitative variables. Population - PRECISE ANSWER An entire pool from which a sample is drawn. Multiplication Rule for Independent Events - PRECISE ANSWER 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 - PRECISE ANSWER D..
Rational Number - PRECISE ANSWER 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 - PRECISE ANSWER A symbol used to denote percentages. Horizontal Line - PRECISE ANSWER 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 - PRECISE ANSWER The difference, in value, between the bottom and top 25 percent of the sample or population. Box Plot - PRECISE ANSWER 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 - PRECISE ANSWER In an experimental study, this group does not receive treatment or receives a placebo. Venn Diagram - PRECISE ANSWER A type of chart that illustrates distinct sets, topics, or objects relate to one another. Uses circles to represent events.

A. .075mL B. 2.7mL C. 75mL D. 270mL - PRECISE ANSWER D. 270mL Base Number - PRECISE ANSWER 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 - PRECISE ANSWER Sequence of zeros after the last non- zero digit in a decimal number.
Correlation - PRECISE ANSWER An observed relationship between two quantitative variables. While this is most commonly a linear relationship, it does not need to be. Not that observing a relationship does NOT imply that there is a meaningful causal link between the variables. Sample - PRECISE ANSWER The small quantity of data gathered about a population that will represent the population as a whole. What is the Fahrenheit equivalent for a patient's room that needs to be kept at 25 degrees Celsius? A. 70° B. 75° C. 77° D. 80° - PRECISE ANSWER C. 77° Multiplicative Inverse - PRECISE ANSWER 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 - PRECISE ANSWER A decimal number that has a finite number of digits. Slope-Intercept Form - PRECISE ANSWER 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.
