number of cars moving between the intersections. To keep the traffic moving smoothly, the number of cars entering the intersection per hour must equal the number of cars leaving per hour. 1. Describe the situation. 2. Create a system of linear equations using a, b, c, d, e, f, and g that models continually flowing traffic. 3. Solve the system of equations. Variables f and g should turn out to be independent. 4. Answer the following questions: a. List acceptable traffic

Executive Summary This paper will use both simple and multiple linear regression techniques to show the relationship between the amount of a bill and the number of days it takes to collect for both commercial and residential accounts for Quick Stab Collection Agency. It will examine if the size of the bill impacts the time it take to collect, analyze the differences between procuring delinquent residential and commercial bills and recommend strategic actions that may be taken to maximize Quick Stab

A linear regression is worth a maximum of 5 points; a multiple regression is worth a maximum of 10 points and both are worth 13 points. You must analyze the regression(s) that you do. The better job that you do, for instance, checking the residuals and for multicollinearity, the more points you get. If you choose to do a linear regression then you must compare the list price to the square footage. You are to project out the listing price of a home that has 2750 square feet. If you choose to do the

Background Information: In this lab, the different positions of a battery powered toy car moving in one direction over time (Velocity) was measured and recorded. Time and distance were the two physical quantities measured in this lab. A stopwatch and a meter stick were used to measure the distance the toy car travelled in a specific amount of time. Once the data points were collected and plotted, the relationship between the points was found using a line of best fit, which was in the form of y=mx+b

| Crime in the United States | Data Analysis Project | | Brad Davidson | | 12/2/2010 | | Executive Summary This purpose of this report is to answer the question, “what variables affect the level of crime in the United States?” With so many possible influences, the goal of this analysis will be to narrow the scope to the items which we feel will be most statistically significant when gauging the effect on the level of crime. The regression analysis methodology is best suited

Vector methods have become standard tools for the physicists. In this chapter we discuss the properties of the vectors and vector ®elds that occur in classical physics. We will do so in a way, and in a notation, that leads to the formation of abstract linear vector spaces in Chapter 5. A physical quantity that is completely speci®ed, in appropriate units, by a single number (called its magnitude) such as volume, mass, and temperature is called a scalar. Scalar quantities are treated as ordinary real numbers
