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.]

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
