- Table 6 shows the population, in thousands, of harbor seals in the Wadden Sea over the years 1997 to 2012. a. Let x represent time in years starting with x=0 for the year 1997. Let y represent the number of seals in thousands. Use logistic regression to fit a model to these data. b. Use the model to predict the seal population for the year 2020. c. To the nearest whole number, what is the limiting value of this model?What does the y -intercept on the graph of a logistic equation correspond to for a population modeled by that equation?Graph the following logistic function, first discussed in Example 5. Use window settings of 0,20 for x and 0,1,500,000 for y. Pt=1,200,0001+1199e-0.4t
- Enter the data from Table 2 into a graphing calculator and graph the ranking scatter plot. Determine whetherthe data from the table would likely represent a function that is linear, exponential, or logarithmic.Which of the following conclusions is not supported by data in the graph? 1. The ratio of biomass to fossil fuel extraction did not change that much in that time. 2. Overall, fewer tons of metals were extracted than minerals. 3. The extraction of all four types of natural resources - biomass, minerals, metals and fossils fuels - increased steadily for several decades after 1980. 4. Biomass energy is a renewable resource.
