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

This document contains 10 questions that students are asked to solve or simplify using the graphing calculator. The last two pages of the document include an answer key as well as explanations as to how students would have made the most common mistakes. Rounding, substitution, scientific notation, More… square roots, radicals, negatives, exponents, absolute values, mixed numbers, improper fractions, simple right triangle trigonometry are addressed

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

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

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

This PowerPoint document will help students understand how to read, create and interpret Venn diagrams

Bell Ringer When am I ever going to use this stuff? Recently, we went to dinner and used a 10% off coupon. The bill and coupon are attached. The discount is shown at the bottom. Was the discount applied correctly? If not, then what should the discount have been instead? Is there an easy way to find a 10% off discount?

Dolbear theorized that the temperature can be computed by counting the number of times a cricket chirps in 15 seconds, and then adding 40 for the temperature in degrees Fahrenheit. For example, if a cricket chirped 20 times in 15 seconds, Dolbear theorized that would mean that the outside temperature was 60 degrees Fahrenheit. Find a linear equation that relates cricket chirps to degrees Fahrenheit. Use N for number of chirps and F for Fahrenheit.

Students often approach me with graphing calculators and say “This is broken,” or “the batteries are dead.” More often than not, the calculator is still usable. This guide should help you restore life to many of those calculators, AAA, texas instruments, TI83, Nspire
