Students will be asked to create two scatter plots (one for games 1-23 and a second for games 24-46). Students will then choose appropriate regression models for the growth of advertising costs. Students will choose these models based on visual representations as well as appropriate r or r2 values. Teachers can also introduce residuals here. Teachers can also help the students graph the equations as a piecewise function so that they can see the change in growth rate. Super Teachers need to

President Barack Obama was sworn in to office for his second term on January 21, 2013. This inauguration was held on Martin Luther King Day. Whether you are a member of the Democratic or the Republican Party, there is historical significance to the swearing in on that holiday. Dr. Martin Luther King, Jr. was asked about whether he thought there would ever be a President of color. "I've seen levels of compliance with the civil rights bill and changes that have been most surprising," King had

Several High School students use the TI84 graphing calculator for their math classes. The most asked questions are always “How do I do this” and “My calculator is broken, how do I fix it?” This brief tutorial should help you with some of the basic instructions for students and teachers to get started on the calculator. Please look for other files helping with graphing, regressions and other calculator steps. 1. Resetting the Calculator 2. Changing between Radian and degree modes 3. Catalog 4. No

Several High School students use the TI84 graphing calculator for their math classes. The most asked questions are always “How do I do this” and “My calculator is broken, how do I fix it?” This brief tutorial is the second in a series. The first tutorial addressed Resetting the Calculator, Changing between Radian and degree modes, Catalog, Normal and Scientific Notation and Storing Values. This tutorial will address graphing equations and inequalities. Please look for other files helping wit

Many homeowners try to pay more on their mortgage each month in the hopes that it will save them money in the long run. Is this an accurate belief? For this exercise, you will determine the minimum payment for different mortgage products. You will also decide whether it is worth paying early. Note this exercise will not address the possibility of late or early payments, tax breaks for making an extra payment every year and other variables. Some of those are addressed in the extension assignment

Postal rates have been figured by the ounce since July 1, 1885. Students• This activity allows the students to create graphs and equations based on the price of mailing a letter up to one ounce. The explanation of reasoning pieces are important as we move to the common core and also are more aware of the importance of English results

One of the most underused functions of the TI84 calculator is the solver function. This function allows the user to either check their answer, or to find a solution to an equation that they are unable to solve. The keys to this function are that the equation must be equal to zero and the user must be able to input “guesses.” The other key to using the solver function is the user must be able to properly use parentheses. MathPrint does not work on the Solver. exponential growth decay, linear,

The TI84 calculator has many built in functions that are never used. This document is designed to be a quick tutorial on how to use many of the most useful ones. All of the functions can be found by going through the CATALOG (2ND 0). There are other methods for reaching each of these functions, however, this tutorial will not address those directions, absolute value, circle, factorial, conjugate, gcf, gcd, lcm, remainder, divisor,

Based on the table, how much more will an adult with an Associate degree earn than a person with a high school diploma over the course of a 40 year work career? Is there a greater difference in the median salaries between No high school diploma and High school diploma, or between a high school degree and an Associate degree? If the same student is not a New York State resident, then the cost increases. What is the total cost of a two year degree for a non-New York resident? How long will it t

Students in Algebra 2 and other advanced classes are often asked to graph and evaluate piecewise functions. These problems are much easier to evaluate if you can use the power of the graphing calculator to graph and view the resulting function. A typical example is f(x) Students can enter this function (note it is a function, because there is only one value of y for every x), into Y= and graph. In the past, students would enter into Y1 and then into Y2.

Many students will be heading off the college in the coming years, and some don’t have a comprehension of money. This assignment, while it is a bit far-fetched, will better help them to prepare for their move into a college dorm. The expenses will be different for that move (a bed is usually included, but most students want their own mini-fridge and/or microwave), but the research will be very similar.

Some questions in algebra and algebra 2 will ask for the equation of a curve or correlation coefficient. The r-value number describes both how well the equation of the curve fits and whether the graph is increasing or decreasing. The r- value will be positive if the graph is increasing and the r-value will be negative if the graph is decreasing. The closer the absolute value of r is to 1, the better the curve fits the data. An r-value of 1 means the curve fits the data perfectly and has a positi

Step 1: Solve for x or y in one equation. Choose the x or y that has either a 1, 2, 4 or 5. Look for the multiples in that order. NEVER CHOOSE AN X OR Y WITH A "3" as your keeper. ? Step 2: Substitute your new value into the other equation. This will create a longer equation, but the equation will have only one variable and will be much easier to solve. ? Step 3: Solve for x AND solve for y. ? Step 4: Check your answers algebraically by substituting your found values into both equation

How much math is incorporated in theme parks? The following eleven questions are geometry review questions that are also centered around theme parks. Please answer each question, showing all work. So put on your swim suits and break out the sun screen and lets go to the theme park. Circles, logic, c More…onstructions, parabolas, arcs, volume, equations of a line and area are addressed

Students are given the length and speeds of 9 different animals and then asked to determine the equation of the curve of best fit. Students are then asked to explore whether the equation would fit other animals including humans. Students are asked to identify possible outliers to the data
