Compute a Matlab script: Suppose we have two species of animals, foxes and rabbits and we wish to model their population Suppose the number of foxes at a given time is given by yn and the number of rabbits is given by rn. Suppose in the absence of predation, rabbits reproduce at a rate proportional to their population rn with constant of proportionality a. Suppose the rate at which foxes eat rabbits is proportional to the number of foxes with...
Population growth problems BIDE model: No.1 N, +(B + 1) - ( D Rates: b = B/N; d = D/N: E) Net growth rate: R = b-d Exponential growth (discrete): N, NR* where R = 1+b-d Intrinsic rate of increase: r = InR Exponential growth (continuous): N:Noe -or-dN/dt = IN Logistic growth 1. Suppose a species of fish in a lake is modeled by a logistic population model with relative growth rate ofr 0.3 per year and carrying capacity of...

When a new item is purchased, its value typically decreases over time. We call this depreciation. Vehicles, computers, and machinery are all examples of items that depreciate in value. The value of a sports car is given by the equation V = 35000(0.85)" + 1000, where V is the value in dollars, and n is the age of the...
Given this bird population growth data, answer the followign questions: 1) Explain why you think the population grew in the pattern it did 2) Model the population as closely as possible using the logistic equation. Lowever to do so, you'll need to predict the intrinsic rate of increase and carrying capacity. Estimate these vales as must as possible. Report the estimated R and K and graph 1) the populations (both modeled and real on the same graph) against time, 2)...
Suppose we are interested in estimating the proportion p of a population that has a certain disease. As in Section 2.3 let y;-1 if person i has the disease, and yi 0 if person i does not have the disease. Then p . a Show, using the definition in (2.13), that 22 N- np If the population is large and the sampling fraction is small, so that write (2.26) in terms of the CV for a sample of size 1....

In October 2001, Environment Canada introduced the wind chill index above. Each curve represents the combination of air temperature and wind speed that would produce the given wind chill value. For example, a temperature of -25°C and wind speed...
Page 1 Question 1 Suppose we take repeated random samples of size 20 from a population with a Select all that apply. mean of 60 and a standard deviation of 8. Which of the following statements is 10 points true about the sampling distribution of the sample mean (x)? Check all that apply. A. The distribution is normal regardless of the shape of the population distribution, because the sample size is large enough. B. The distribution will be normal as...

please help me with these problems. thank you Introduction The Island of Daphne Major, one of several islands that make up the archipelago of islands off the coast of Ecuador, supports a population of ground finches, Geospiza fortis. Finches are small songbirds with chunky beaks which they use to crack open seeds from various shrubs and trees on the island. These seeds make up most of the finch diet. Biologists have been studying this population for over 30 years. Each...
