A scientist kept 1,000 gram samples of radioactive carbon, radium, and plutonium in three different containers. The table below shows the half-lives of the three radioactive materials.
Radioactive Material | Half-life (in years)
carbon | 5,700
radium | 1,620
plutonium | 6,563
Based on the table, which of these conclusions is most likely correct?
1. After 6,000 years, approximately 250 grams of carbon and radium will be left in the containers.
2. After 20,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.
3. After 20,000 years, approximately 250 grams of carbon and radium will be left in the containers.
4. After 6,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
