A corporation that manufactures electronics makes computer chips, transistors, and resistors. Four units of copper, one unit of zinc, and two units each of glass are needed to make one transistor. Each computer chip needs two, one, and three units of these materials, whereas each resistor needs three, three, and one units of each of the three materials. When we convert this data into a table, we get:

Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2), which contributes to global warming. The CO2 emissions (metric tons per capita) for countries varies from 0.02 in Burundi to 44.02 in Qatar. Although the data set includes 214 countries, the CO2 emissions of 15 countries are not available on the World Bank database. The data set is too large to display but the data for the first five countries is given. Use the full data set with data on the 214 countries to answer the questions.

In your biology class, your final grade is based on several things: a lab score, score on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 30% of your total grade, each major test is worth 22.5%, and the final exam is worth 25%. Compute the weighted average for the following scores: 95 on the lab, 84 on the first major test, 91 on the second major test, and 82 on the final exam. Round your answer to the nearest hundredth. 87.72 88.37 84.47 091.62 86.80

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 21%, and the final exam is worth 35%. Compute the weighted average for the following scores: 95 on the lab, 67 on the first major test, 72 on the second major test, and 76 on the final exam.
