Suppose the likelihood that a child will attend a live theatrical performance can be modeled byq = 0.01(-0.0076x² + 1.4x + 4.1)(15 < x< 100).%3DHere, q is the fraction of children with annual household income x thousand dollars who will attend a live dramatic performance at a theater during the year. Compute the income elasticity of demand E at an income level of$20,000. (Round your answer to two decimal places.) HINT [See Example 2.]E =Interpret the result.At a family income level of $the fraction of children attending a live theatrical performance is increasing by% per 1% increase in household income.

On the basis of data for the years 1912 through 1992, the expected life span of people in a country can be described by the function f(x) = 12.663 In x+17.681 years, where x is the number of years from 1900 to the person's birth year. What does this model estimate the life span to be for people born in 1937? This model estimates that the life span for people born in 1937 is (Round to the nearest year as needed.) years.
The demand for ceiling fans can be modeled below as D(p) = 25.62(0.996P) thousand ceiling fans where p is the price (in dollars) of a ceiling fan. (a) According to the model, is there a price above which consumers will no longer purchase fans? Explain why or why not. The model is exponential and ---Select--- ✓the horizontal axis. Therefore there ---Select--- above which consumers will not purchase a ceiling fan. (b) Calculate the amount that consumers are willing and able to spend to purchase 17 thousand ceiling fans.

Suppose a species of fish in a particular lake has a population that is modeled bythe logistic population model with growth rate k, carrying capacity N, and time tmeasured in years. Adjust the model to account for each of the following situations. * One hundred fish are harvested each year.* One-third of the fish population is harvested annually.* The number of fish harvested each year is proportional to the square root of thenumber of fish in the lake. I was hoping to compare my answer to yours because I am a little confused if I did it right. Thank you for your time and effort.
