Before 1918, approximately 60% of the wolves in a region were male, and 40% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 65% of wolves in the region are male, and 35% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before 1918, in a random sample of 12 wolves spotted in the region, what is the probability that 9 or more were male?What is the probability that 9 or more were female?What is the probability that fewer than 6 were female?(b) For the period from 1918 to the present, in a random sample of 12 wolves spotted in the region, what is the probability that 9 or more were male?What is the probability that 9 or more were female?What is the probability that fewer than 6 were female?
Suppose a small quantity of radon gas, which has a half-life of 3.8 days, is accidentally released into the air in a laboratory. If the resulting radiation level is 30% above the safe level, how long should the laboratory remain vacated? (Hint: To start with, determine what fraction of the "resulting radiation level" is the maximum safe level.) The laboratory should remain vacated for days.
Q1. Assume that the rate at which radioactive nuclei decay is proportional to the number of such nuclei that are present in a given sample. In certain sample 10% of the original number of radioactive nuclei have undergone disintegration in a period of 100 years. a) What percentage of the original radioactive nuclei will remain after 1000 years? b) In how many years will only one-fourth (1/4) of the original number remain?

What is the probability that fewer than 4 were female?

What is the probability that 7 or more were female? What is the probability that fewer than 4 were female?

3. (5.7.12) On June 2, 2010 USA Today reported a story from Bloomberg News that said that the total price tag for the project to build the new F-35 Joint Strike Fighter would be 65% higher than the original $232 billion estimate. The cost now is estimated to be $382 billion. The total cost of each plane would be $112.4 million, up 81% from the original $62 million. The cost to produce each plane would be $92.4 million, about 85% higher than the original estimate of $50 million. a. Check the arithmetic to see that the three percentage increases reported are correct. b. Can you explain how the project cost can have increased by just 65% when the overall total per plane increased by 81% and the construction cost alone increased by almost 85%?
2. A town has a population of 8400 in the year 1990. Fifteen years later, its population grew to 12,500. A) Determine the growth rate of this town's population. B) Predict the population in the town in the year 2050. C) In which year would the town's population be just above 20,000? D) If this model were valid until only the year 2090, determine the domain and range of this model.
2.) Consider an M/M/2 system with an arrival rate of 9 per minute and a service rate of 8 per minute. What is the average time a customer spends in the system? Take your answer to three decimal places. Omit the units in your answer.
India has average precipitation of 1083 mm per year. On a random week in India, what is the expected rainfall as measured in inches per week? Use your E(aX+b) formula, and the fact that 1 mm is equal to 0.0393701 inches, and there are 52.1429 weeks in a year. (Round your answers to two decimal places; ex: 1.23). The United Arab Emirates has average precipitation of 78 mm per year. On a random week in United Arab Emirates, what is the expected rainfall as measured in inches per week?
