After this lesson, you will be able to: Given the vertex of parabola, find an equation of a quadratic function Given three points of a quadratic function, find the equation that defines the function Many real world situations that model quadratic functions are data driven.

Graphs of Two Variable Functions Many types of economic problems require that we consider two variables at the same time. A typical example is the relation between price of a commodity and the demand or supply of that commodity. The student will solve inequalities with one variable and graph the solution. Additional Learning Objective(s): The student will learn to effectively communicate ideas in . Selection File type icon File name Description Size Revision Time User.

This data set contains body measurements body fat percent calculated using 2 different methods for a random sample of college graduates.

Make histograms of adiposity, fatpct1, fatpct. Superimpose a normal curve on them. Do any of these distributions appear approximately normal? Include the histograms with appropriate titles and labeling in your response.

NORMALThese instructions generate a random sample from a normal distribution with a mean of and a standard deviation of Make a histogram of Calories and superimpose a normal curve on it. If it was exactly normally distributed then it would have the mean and standard deviation you requested.

If Calories is exactly normally distributed, what percentage of cases should have values between and ? What percentage of cases in your sample have Calories in this range? What percentage of cases would you expect to have Calories or more if Calories is exactly normally distributed?

What percentage of cases in your sample have Calories greater or equal to ? What percentage of cases in your sample have Calories less than ?

What would you expect if the distribution is exactly normal?

This creates a new variable in your dataset called zcalories, what the z-score of calories would be for each subject in your dataset. Make a histogram with a normal curve superimposed. Is this what you expected? Between 0 and 1. What are the null hypothesis you want to test?

Test the hypotheses and write a brief summary of your conclusions. You have ONE sample. Describe the age and gender composition of those in the sample.Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations.

Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

Solving Quadratic Inequalities in One Variable Video Homework: Page #4, 5, 6, 7a, 9a. Solving Quadratic Inequalities in One Variable – Part 2. Use Compute to create a new variable that is the difference between the between the two body fat percent variables (variables fatpct1 and fatpct2).

(Hint: use Transform à Compute) a. It has been proposed (e.g. in the ENCODE DCC grant proposal) that we design a new graphing data format that will preserve the submitted data exactly.

Lacking this, we have promised to provide for download an additional copy of each ENCODE dataset as originally submitted. B) change in the horizontal variable divided by the change in the vertical variable. C) the vertical axis divided by the horizontal axis.

D) change in the vertical variable. Internal Assessment Proposal What instrument would you use to measure each variable?

(if applicable) Choose two variables to investigate – one for your IV, the other for your DV Spreadsheets and graphing software can be used in all investigation types. In some cases, real data can be.
