Suppose that trees are distributed in a forest according to a two-dimensional poisson process with parameter α, the expected number of trees per acre, equal to 40. (a) what is the probability that in a certain quarter-acre plot, there will be at most 15 trees? (round your answer to three decimal places.) (b) if the forest covers 70,000 acres, what is the expected number of trees in the forest? trees (c) suppose you select a point in the forest and construct a circle of radius 0.1 mile. let x = the number of trees within that circular region. what is the pmf of x? [hint: 1 sq mile = 640 acres.]

What are the digits that repeat in the smallest sequence of repeating digits in the decimal equivalent of 24/11?

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?

Bonnie and bobby are saving money for a vacation. each friend starts with an amount and also saves a specific amount each week. bonnie created a table to show the total she has saved at the end of each week.. weeks 0 1 2 3 4 5 6 7 8 amount saved 12 16 20 24 28 32 36 40 44 bobby came up with the following equation to show the total, y, he has saved at the end of each week, x. y = 12x + 4 compare the rate at which each friend saves money. select the correct answer from the drop-down menu to complete the statement. the rate at which bobby is adding to his savings each week is $ more than the rate at which bonnie is adding to her savings each week.
