SOLVED: CURRENT OBJECTIVE Compute probability using the exponential distributionQuestion Carbon-14, radioactive isotope of carbon; decays at a rate of 14 disintegrations per minute (per gram of natural carbon): Assuming that the time between disintegration events has an exponential distribution; calculate the probability that such an event takes more than 12 seconds to occur. Round your answer to four decimal digits and do not include units in your answer

SOLVED: The half-life of the radioactive isotope Carbon-14 is about 5730 years. (a) Use Equation 6.5 to express the amount of Carbon-14 left from an initial N milligrams as a function of time t in years. (b) What percentage of the original amount of Carbon- 14 is left after 20,000 years? (c) If an old wooden tool is found in a cave and the amount of Carbon-14 present in it is estimated to be only 42 % of the original amount, approximately how old is the tool? (d) Radiocarbon dating is not as eas

SOLVED:The radioactive isotope carbon 14 is present in small quantities in all life forms, and it is constantly replenished until the organism dies, after which it decays to stable carbon- 12 at a rate proportional to the amount of carbon-14 present, with a half-life of 5730 years. Let C(t) be the amount of carbon- 14 present at time t (a) Find the value of the constant k in the differential equation C^'=-k C (b) In 1988 three teams of scientists found that the Shroud of Turin, which was reputed
