Biology a lake is stocked with 500 fish, and the fish population p begins to increase according to the logistic growth model
p = 10,000/1 + 19e-t/5, t > 0
where t is measured in months.
(a) find the number of fish in the lake after 4 months.
(b) use a graphing utility to graph the model. find the number of months it takes for the population of fish to reach 4000.
(c) does the population have a limit as t increases without bound? explain your reasoning.

If given an equation of a line such as -1/2x+6 how would you create an equation of a line parallel and perpendicula to this line that goes through another point such as (4,10)

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
