Radioactive atoms are unstable because they have too much energy. When they release their extra energy, they are said to decay. When studying a particular radioactive element, it is found that during the course of decay over 365 days, 1,000,000 radioactive atoms are reduced to 979,424 radioactrive atoms. Find the mean number of radioactive atoms lost through decay in a day. mean = Find the probability that on a given day 64 radioactive atoms decayed. P(X = 64) =

When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 973,846 radioactive atoms, so 26,154 atoms decayed during 365 days. a. Find the mean number of radioactive atoms that decayed in a day. b. Find the probability that on a given day, 51 radioactive atoms decayed.

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...

CASE 20 Enron: Not Accounting for the Future* INTRODUCTION Once upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant "E" slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm...
