the population P (in thousands) of a certain city from 2000 through 2008 can be modeled by p=280.84e^kt where t is the year with t=0 corresponding to 2000. in 2006 the population was about 360,000. (a) finf the value of k for the model. round your result to four decimal places (b) use your model to predict the population in 2015(round your answer to the nearest person p=?? 16. 1/2 points Previous Answers LarATRMRP7 4.5.0183/30 Submissions Used My Note Corplete...
The amount of garbage, G, produced by a city with population p is given by G = f(p). G is measured in tons per week, and p is measured in thousands of people. a. The town of Tola has a population of 50,000 and produces 12 tons of garbage each week. Express this information in terms of the function f. Enter your answer as an equation. Do not enter an any units (people, tons) or commas in your answer. Include...
The population of fish, P, in a lake is a function of time, t, measured in years. The rate of change of P is given by 7600e0.4t fish/year. dt(19 + e0.4t)2 dp dt a. Graph on the domain [0, 20]. Make sure your graph is properly labeled. b. Estimate the change in population on the time interval 0 s t š 20 years. Use 10 intervals, each lasting two years.

1. Suppose an economy is represented by the following equations: C=500+.75(Y-T) I=1000 -50r (M/P)d=Y-200r G=1000 T=1000 M=6000 P=2 Use these equations to derive both the IS and LM curves. Suppose that a newly elected president cuts taxes by 20%. Assuming that the money supply is held constant, what is the equilibrium interest rate in this economy? Round your answer to the nearest tenth. Do not use a percent sign when entering your answer. Your answer should not be given as...
3. The population of a city is given by P 250000(1.25)n/20 where n is the n years after 2005. What is the population in 2035. 5 Marks 4. The sales of a small company were $ 27000 in its 2md operation and S 63000 in its 5 year of operation. Assume that the data can be year.

2. After conducting a census in 1970, the family incomes in a certain city were found to have a mean of $14,200 with a standard deviation of $2600. A random sample of 75 families taken in 1975 produced x¯ = $14, 930 (in 1970 dollars, after adjusting for inflation). Assume throughout this problem that the standard deviation of family incomes is the same in 1975 as it was in 1970. a) Identify each of the numbers $14200, $2600, and $14930...
1. In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land use. The assumptions are: • all dwellings are situated within apartment complexes, • all dwellings must contain exactly 1,500 square feet of floor space, re- gardless of location, and • apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling...
In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land-use. The assumptions are: (i) all dwellings must contain exactly 1500 square feet of floor space, regardless of location, and (ii) apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling sizes and building heights do not vary with distance to the...

The reading speed of second grade students in a large city is approximately normal, with a mean of 91 words per minute (wpm) and a standard deviation of 10 wpm. Complete parts (a) through (f). (a) What is the probability a randomly selected student in the city will read more than 96 words per minute? The probability is nothing. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer...
