Identify the correct leading coefficient, degree, and end behavior of P(x) = 4x^5 + 9x^4 + 6x^3 − x^2 + 2x − 7.
A. leading coefficient: 5
degree: 4
end behavior:
as x → −∞, P(x) → +∞
as x → +∞, P(x) → −∞
B. leading coefficient: 5
degree: 4
end behavior:
as x → −∞, P(x)→ −∞
as x → +∞, P(x)→ +∞
C. Leading coefficient: 4
degree: 5
end behavior:
as x → −∞, P(x) → −∞
as x → +∞, P(x) → +∞
D. leading coefficient: 4
degree: 5
end behavior:
as x → −∞, P(x)→ +∞,
as x → +∞, P(x)→ −∞

Exclude leap years from the following calculations. (a) compute the probability that a randomly selected person does not have a birthday on october 4. (type an integer or a decimal rounded to three decimal places as needed.) (b) compute the probability that a randomly selected person does not have a birthday on the 1st day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (c) compute the probability that a randomly selected person does not have a birthday on the 30th day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (d) compute the probability that a randomly selected person was not born in january. (type an integer or a decimal rounded to three decimal places as needed.)
