Assume that in a trivia contest, a caller will have the correct answer with probability  p = 0.24. Assume calls are independent.  The winner of the contest will be the second person with the correct answer.  This copywritten question is part of a quiz or exam at Arizona State University. It may not be posted on Chegg or any other online site without permission from Dr. L. Chattin.   If you wanted to determine the probability that it will take more than five callers before the winner of the contest is identified, which distribution would you need to use?  Hint: Define your random variable in words, first.

Refer to the figure. What was the ultimate cause of the increase in mouse density according to this figure?  

Refer to the figure.   Based on the figure, what year is the population growth rate expected to be only 1%?

Refer to the figure. The low-lying shrub-covered heathlands of England once covered large, continuous areas, but over the past 200 years the development of farms and urban areas has greatly reduced the extent of heath plant species. The development and subsequent decline in habitat can best be described as

The logistic equation assumes that

Refer to the figure.   Based on the figure, what is the highest density of red kangaroos that can be found along the coastlines of Australia?  

A population of prickly pear cacti has 1,500 individuals with an intrinsic rate of increase (r) of 0.3. As the population gets close to its carrying capacity of 2,000 individuals, how will r change?
