Until the Sun Dies. It took 65 million years from the time the dinosaurs were wiped out by an asteroid impact until humans arrived on the scene. Today, we have the technology to wipe out all humans, if we do not use our technology wisely. Suppose we wipe ourselves out, and then it takes 65 million years for the next intelligent species to arise on Earth. Then suppose the same thing happens to them, with another intelligent species arising 65 million years later. If this process could continue until the Sun dies in about 5 billon years, how many more times could intelligent species arise on Earth at 65-million-year intervals?

After a person becomes infected and then recovers, the person is immune cannot become infected again. Of the people who are infected, 5 will die each year and the other will recover. Of the people who have never been infected, 25 will become infected each year. How many people will be infected in 4 years?arrow_forward
- Like any seeds, watermelon seeds lose their viability over time. If they've been left sitting for years, it's possible that only a small proportion of the seeds may sprout when planted. If they have been stored in a cool, dark, dry location, they have a better chance of sprouting. Drake has a large quantity of old watermelon seeds he's been saving, and now wants to know how many of them may still be able to sprout. He randomly selects 50 seeds from the set, places them between damp paper towels, and puts them in a plastic baggie in a warm spot on the counter. He finds that 27 out of the 50 seeds do sprout. Does this provide good evidence that over half of all of the seeds will sprout? (a) What proportion of Drake's tested seeds actually sprouted? p = (b) State the appropriate null and alternative hypotheses. р ? 0.5 Ho: на: р ? 0.5 (c) What is the value of z, the test statistic, for this test?

Each satellite has fuel to last about five years, upon which it will steer itself into the atmosphere in order to burn up. On average about four satellites per day are expected to do this. Some satellites may not burn up completely and fragments large enough to cause injury may reach the surface of the Earth. The company estimates that about 10 such fragments per satellite on average will reach the surface of the Earth. The probability that the company's satellite constellation will cause an injury is 0.43 every five years. Assume a Poisson distribution for fragments of satellites causing injury. Complete parts (a) through (d). a) What is the expected number of injuries every five years? (Round to three decimal places as needed.) b) What is the expected number of injuries per year? .

If there are 1000 mosquitoes initially and there are 1600 after 1 day, what is the size of the colony after 2 days? How long is it until there are 30,000 mosquitoes? The size of the colony after 2 days is approximately mosquitoes. (Do not round until the final answer. Then round to the nearest whole number as needed.) There will be 30,000 mosquitoes in the colony in about days. (Do not round until the final answer. Then round to the nearest tenth as needed.)arrow_forward

This isotope is not very stable due to radioactive decay. Two-thirds of the original radioactive material loses its radioactivity after each month. If 13 grams of this isotope are released into the atmosphere at the end of the first and every subsequent month and the situation goes on ad infinitum, how many grams of radioactive material are in the atmosphere at the end of each month in the long run?arrow_forward
- . The earth has more than 7 billion people and almost no one lives 100 years. Assume that nobody make it past age 100. How do you know that, some year soon, more than 50 million people will diearrow_forwardUnder certain water conditions, the free chlorine (hypochlorous acid, HOCI) in a swimming pool decomposes according to the law of uninhibited decay. After shocking a pool, the pool boy, Geoff, tested the water and found the amount of free chlorine to be 2.7 parts per million (ppm). Twenty-four hours later, Geoff tested the water again and found the amount of free chlorine to be 2.4 ppm. What will be the reading after 3 days (that is, 72 hours)? When the chlorine level reaches 1.0 ppm, Geoff must shock the pool again. How long can Geoff go before he must shock the pool again? After 3 days, or 72 hours, the amount of free chlorine in the pool will be ppm. (Do not round until the final answer. Then round to the nearest hundredth as needed.) Geoff will need to shock the pool again in hours. (Do not round until the final answer. Then round to the nearest tenth as needed.)arrow_forwardA private space company is launching a network of about 11,000 satellites to provide internet connectivity globally. Each satellite has fuel to last about seven years, upon which it will steer itself into the atmosphere in order to burn up. On average about four satellites per day are expected to do this. Some satellites may not burn up completely and fragments large enough to cause injury may reach the surface of the Earth. The company estimates that about 10 such fragments per satellite on average will reach the surface of the Earth. The probability that the company's satellite constellation will cause an injury is 0.39 every seven years. Assume a Poisson distribution for fragments of satellites causing injury.
