Let x, the number of flaws on the surface of a randomly selected boiler of a certain type, have a poisson distribution with parameter μ = 5. use the cumulative poisson probabilities from the appendix tables to compute the following probabilities. (round your answers to three decimal places.) (a) p(x ≤ 7) (b) p(x = 7) (c) p(9 ≤ x) (d) p(5 ≤ x ≤ 7) (e) p(5 < x < 7)

it is a secret for it not to be compromised sorry

step-by-step explanation:

60 for the first and 130 for the second

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
