A. +/- 2.3 B. +/- 3.3 C. +/- 4 D. +/- 5 Correct Answer: D. +/- 5 Composite Number Correct Answer: A number with more factors that just one and itself. Equivalent Fractions Correct Answer: Different fractions that represent the same value. X-Axis Correct Answer: The horizontal line that passes through the origin on a coordinate plane. Qualitative Data Correct Answer: Non-numeric information based on some quality or characteristic. No Correlation Correct Answer: There is no apparent overall trend between the two variables. If the correlation coefficient is 0, this only rules out a linear trend. There could be a non-linear or curvilinear trend.

Outlier Correct Answer: An observation point that is statistically distant from the other observations in the dataset. Regression Line Correct 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 Correct 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?
