What exactly are compartments in compartmental modeling? Can you broadly, yet intuitively, explain?

A tenet of the scientific method is that -------------------------------allow researchers to examine mental processes and behavior in an empirical, scientific manner.

DATAfile: Landscape David's Landscaping has collected data on home values (in thousands of $) and expenditures (in thousands of $) on landscaping with the hope of developing a predictive model to help marketing to potential new clients. Data for 14 households may be found in the file Landscape. HomeValue($1,000) LandscapingExpenditures($1,000) 242 8.1 321 10.8 198 12.2 340 16.2 300 15.6 400 18.9 800 23.5 200 9.5 521 17.5 547 22.0 437 12.1 464 13.5 635 17.9 356 13.9 (a) Develop a scatter diagram with home value as the independent variable. A scatter diagram has a horizontal axis labeled "Home Value ($1,000)" with values from 0 to 900 and a vertical axis labeled "Landscaping Expenditures ($1,000)" with values from 0 to 25. The scatter diagram has 14 points. A pattern goes down and right from (198, 21.9) to (800, 6.5). The points are scattered moderately from the pattern.   A scatter diagram has a horizontal axis labeled "Landscaping Expenditures…

Textbook exercise: A city’s status and living conditions may affect how its residents perceive their mayor and city council. Dr. Benevita has used data from Statistics Canada to rank larger metropolitan areas against each other. Focusing on unemployment rates, median household income, and crime rates, he has given Calgary an overall positive ranking (low unemployment, high income, and relatively low crime), and Winnipeg an overall negative one (mid-range unemployment, fairly low income, and very high crime). Dr. Benevita has contacted 40 residents of each city to respond to one simple question: “How competent do you believe your municipal leaders are in governing your city?” Participants rated their municipal government on a scale of -3 (completely incompetent) to +3 (completely competent). A perfectly normal distribution around the central, neutral, point would have a mean of 0 and a standard deviation of 1.66. We will use this as our comparison point to determine whether residents of…

2. Consider the function y(x) = 5x over the interval [0, 10]. (a) If the points A(0, y(0)), B(5, y(5)), and C(10, y(10)) are on the curve represented by the above function, find the slope of the lines (secants) AB, and AC, respectively. (b) If x represents time and y represents the displacement of a particle moving along a line, what is the physical meaning of your results to part (a)? (c) Now consider a point D(10 – h, y(10 – h)) on the curve represented by the given function, find the slope of the line DC. (d) As h → 0, what is the limiting value of your result to part (c)? (e) What is its physical meaning of your result to part (d) if again x represents time and y represents the displacement?
