The following table shows world population N, in billions, in the given year. According to the logistic model N = 10.90 / 1+2.23e^-0.030t, when will world population reach 90% of carrying capacity?

The bass population of a mountain lake was measured a year ago, and the lake was found to host 6,000 bass. If the current bass population is 10,500 and the bass grow according to a logistic growth model with carrying capacity 60,000, determine the growth constant k.k =     What are the units of k? years2years−1     years   plz show step by step 9 )

The exponential growth model of a population in a certain city is A= 20e0.05t, where A is the size of the population in thousands in a particular year, and t is the number of years from the year 2000. a) What is the population of the city in the year 2000? b) What is the population of the city in the year 2020? C) If the rate of change increased after 2020 to 10%, in what year that the population be 200,000? d) What could be the initial population if the number of people is 10, 0000, 000 in 12 years with the same growth rate?

A survey was conducted and asked: "Do you consider your health to be poor?" This was coded as 1 for "yes" and 0 for "no." The effect of age (in years) and sex (1 male, 0 = female) on the outcome was examined using logistic regression. The fitted logistic model is: = logit(ô) = −0.544 + ß * sex + 0.0331 * age (a) What are the odds of responding "yes" for a female subject who is 60 years old? (b) What is the estimated odds ratio corresponding to the age variable? Interpret this estimate. (c) Suppose that, based on the data from the survey, the odds of responding "yes" for males are 3.79% greater than the odds for females, adjusting for age. What is the value of Â? (d) If we only wanted to assess the association between survey response (yes/no) and sex, what other method(s) (that we have learned in this class) could we have used (name at least one)? In your own words, explain why we cannot use the same method(s) if we want to consider the effects of both sex and age on survey response.
