High school graduates need more mathematics than ever before, and they need to know how to use quantitative reasoning, statistical reasoning, and modeling tools to solve problems in applied situations. This 12th-grade capstone course engages students in relevant problems and prepares them for higher education and the workplace. The materials prepare students to use a variety of mathematical tools and approaches to model a range of situations and solve problems. Revised in , Advanced Mathematical Decision Making addresses all the student expectations for the Texas Advanced Quantitative Reasoning course and the majority of the student expectations for similar courses implemented in other states. Please note: the downloadable materials have not been revised or updated to reflect new standards and strategies. To download the materials: We have a short process that gathers basic information about the use of the course.

A weighted average is a type of average where each observation in the data set is multiplied by a predetermined weight before calculation. In calculating a simple average arithmetic mean all observations are treated equally and assigned equal weight. Weightings are the equivalent of having that many like items with the same value involved in the average. A weighted average is most often computed with respect to the frequency of the values in a data set. One can calculate a weighted average in different ways. Each data point value is multiplied by the assigned weight which is then summed and divided by the number of data points.

C Student Activity Sheet 8: Quarterback Ratings The National Football League NFL rates quarterbacks for statistical purposes against a fixed performance standard based on the statistical achievements of all qualified pro passers since This system allows passing performances to be compared from one season to the next. For the first two games of the season, Dallas Cowboys quarterback Tony Romo completed 45 passes in 62 attempts for a total of yards, with 4 touchdowns and 2 interceptions. Verify that Romo s quarterback rating for those games is approximately Round each value to the nearest tenth. He completed 2, passes in 3, attempts for a total of 25, yards, with touchdowns and 85 interceptions.
