Interpreting Categorical And Quantitative Data |
| HSS.ID: Interpret Linear Models |
| HSS.ID.8 | Compute (using technology) and interpret the correlation coefficient of a linear fit. |
| Summarize, Represent, And Interpret Data On A Single Count Or Measurement Variable |
| HSS.ID.4 | Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve. |
| Summarize, Represent, And Interpret Data On Two Categorical And Quantitative Variables |
| HSS.ID.6 | Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. |
Interpreting Functions |
| HSF.IF: Analyze Functions Using Different Representations |
| HSF.IF.7 | Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.★ |
Reasoning With Equations And Inequalities |
| HSA.REI: Represent And Solve Equations And Inequalities Graphically |
| HSA.REI.11 | Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.★ |
|
| HSA.REI.12 | Graph the solutions to a linear inequality in two variables as a half- plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes. |
| Solve Systems Of Equations |
| HSA.REI.6 | Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables. |
|
| HSA.REI.7 | Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = –3x and the circle x2 + y2 = 3. |
Trigonometric Functions |
| HSF.TF: Model Periodic Phenomena With Trigonometric Functions |
| HSF.TF.7 | (+) Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology, and interpret them in terms of the context.★ |
Vector And Matrix Quantities |
| HSN.VM: Perform Operations On Matrices And Use Matrices In Applications. |
| HSN.VM.7 | (+) Multiply matrices by scalars to produce new matrices, e.g., as when all of the payoffs in a game are doubled. |
|
| HSN.VM.8 | (+) Add, subtract, and multiply matrices of appropriate dimensions. |
