Coal (activated carbon) hypothesis accept/reject = ACCEPT: The sample of charcoal and water, after sitting for 48 hours, had a higher ph than the initial water only reading 3. Based on your data, what effect do you predict coal mining has on the environment? Answer = Coal
If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates ≤1,000 grams? Show your calculations. 208 EXERCISE 27 • Simple Linear Regression 6. In the legend beneath Figure 2, the authors give an equation indicating that systolic blood pressure is SBP = 50.3 + 0.12x. If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates 1,001–1,500 grams?
Booker Jones Case 1. Calculate the effect on the financial statements in Exhibits 1 and 2 if the accounting system were changed to incorporate the cost of barrels ($31.50 each) into the inventory accounts. a. What would pretax profit be in 1961? Booker Jones increased production by 20,000 barrels in 1961.
158,012 tons per yr. of carbon dioxide What are the U.S. average household emissions? 31,308 lbs. per month What was your reduced emissions? 1,473 tons of c02 emissions Household Emissions Savings (Answers can be found above bar graphs If you took all actions you would reduce annual emissions by: 1,473 tons of c02 emissions If you took all actions your potential dollar savings would be: $78.00 per yr. Your new total annual estimated CO2 emissions: 156,539 lbs.
i. The world’s population and energy usage have followed similar patterns of growth. Both tables show a relatively steady increase between 1850 and 1950, then over the next 50 years the Growth rates increase rapidly. Question 2 Environmental impact a) The ecological footprint is a model which is used to measure the amount of resources consumed by an individual or group of people .This calculation determines the impact a particular lifestyle has on the environment. Fossil fuels, such as coal, oil and natural gas are energy sources which contain large amounts of carbon, any process that uses fossil fuels will add carbon dioxide to the atmosphere.
In a year 21.3 billion tonnes of carbon dioxide is produced. Only half of it is removed by natural processes while the other half remains in the atmosphere. The amount of carbon dioxides in the air has rapidly increased as the human population has also increased rapidly. As the population increases more automobiles and energy are needed thus, the level of carbon dioxide in the atmosphere increases. the second cause of global climate change is fluorocarbons.

Write an equation that represents this situation. How much will this person make in 10 years? a) y= 80,000(1+.05)* ---> y= 80,000(1.05)* b) y= 80,000(1.05)^10 = $130,311.6 Elective Problem: A car salesman makes $15,000 a year, for every sale he makes he earns an extra $15o. Write an equation that represents this situation.
Exxon Mobil Analysis ExxonMobil, the largest publicly traded petroleum and petrochemical company in the world, began almost 125 years ago as a regional marketer of kerosene in the United States. The enterprise operates in most of the world’s countries under the brand names of Exxon, Esso, and Mobil (Our history, 2012). What follows is a brief analysis based on parts of ExxonMobil’s 2011 and 2012 annual reports. When looking at assets for ExxonMobil, the determination can be made that the majority of its assets are tangible rather than intangible. In 2011, of the $3.31B in total assets reported, $2.15B would be considered tangible: property, plant and equipment.
Customer Analysis The total industrial consumption of cyano-acrylates which the new Bond-A-Matic 2000 would dispense was 265,000 pounds in FY 1978, expected to grow to about 335,000 pounds in FY 1979. Across 16 SIC categories, approximately 174,909 firms currently used cyano-acrylates (at a 15.5% market penetration.) 11% of CA users, i.e. approximately 19,240 firms used over 10 pounds of CAs per year, comprising at-least 75% of total current market. Assuming that growth in the CA segment stagnates, and that only heavy CA applicators would be interested in dispensing equipment the total market is still estimated at 19,240 users.
