a.
To plot: A regression curve on a scatter plot using the data given below
Given information:
The data is given
The plot of the
Where
The regression model based on the data and the scatter plot is a quadratic regression model.
Graph is given below.
b.
To Explain: how far the person from motion detector to when the person changes the direction using the regression model .
Where distance is in
Given information:
The regression curve is given below.
Where time is in
Based on the data and regression curve can understand the model is quadratic regression model where the relation between time versus distance is about
Based on the time can find the distance the from the motion detector by substituting the value for time

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
