- The diagram below illustrates the electricity generation in ten countries during 2011. (a) Based on the data in the graph, identify one of the fuel sources that in 2011 was intermediate in contribution among the ten countries in the amount of electricity generated. (b) Based on the data in the graph, identify the country that produced a higher percentage of its electricity in 2011 from nonhydroelectric renewables than any other country. (c) Based on the data in the graph, describe one environmental problem in South Korea that could result if its total electricity generation was increased by 10 percent with its most-used fuel source. (d) Based on the data in the graph, propose a solution to reduce an environmental problem linked to the primary means of electricity generation in Brazil, other than reduced use of that resource. (e) The ecological footprint of an average individual living in Canada is seven times larger than the ecological footprint of an average individual living in…Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015.† With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? Suppose the following contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Percentage ofHomes withSmoke Detectors Home Fire Deathsper Millionof Population 0.52 22.8 0.69 20.7 0.76 17.2 0.78 20.4 0.79 19.3 0.84 18.8 0.83 17.5 0.87 16.1 0.88 13.5 0.90 14.3 0.92 14.2 0.94 12.9 0.95 10.8 0.96 10.8 0.97 10.1 0.96 8.3 0.96 8.0 (a) Do you expect a positive or negative relationship between smoke detector use and deaths from home fires? Why or why not? We would expect there would be a ---Select--- negative positive relationship between smoke detector use and deaths from home fires. As more households have…2. As of 2019, Maryland ranked first among the 50 states in average (median) income, at about $86,700 per person, and Mississippi ranked last at $45,800 per person. In the example comparing the median income of people from Maryland and Mississippi, how much higher was the median income in Maryland than in Mississippi? In terms of absolute and relative difference.
- A Gallup survey showed that in March 2011 , 8 of every 25 employers in the United States were adding more workers to their workforce, 9 of 50 were reducing their workforce, and 1 of 2 were keeping it the same. In a metropolitan area there are 1250 employers and of those who will hire, they will hire an average of seven new employees. If the employers who were cutting their workforce in that area were planning on letting go an average of nine workers, what would the net change in jobs for the area be? This metropolitan area would see a ▼net decrease or increase of jobs.The National Highway Association is studying the relationship between thenumberof bidders on a highway project and the winning (lowest) bid for the project.

Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table.

- (Looking at the graph, we can see that the blue line, representing the population proportion in the USA, is consistently increasing over time and eventually reaches a value of around 0.33 (33%) after 100 years. In contrast, the green line, representing the population proportion in China, is decreasing over time and eventually reaches a value of around 0.67 (67%) after 100 years. The red line, representing the population proportion in Canada, remains relatively constant over time and has the lowest value among the three countries) By year 100, the USA has the highest proportion of the population, followed by China and Canada. Does my analysis correct ?In February 2021, the Chicago Tribune reported:“The overdose epidemic that has ravaged Chicago has not spared the nearby suburbs, some of which have death rates comparable to anything seen in the city, according to a report released this week by the Cook County Department of Public Health. ZIP codes in the towns of Worth, Broadview, Maywood, and Forest Park, areas that “have substantially lower median household incomes and higher poverty rates,” have been especially hard-hit, the report said.”In the article, they claimed that lower incomes were associated with higher overdose death rates and that overdose death rates are increasing over time. The data you have been analyzing wasn’t focused on Chicago, obviously. But do your results support the general gist of the statistical argument being made in this Tribune excerpt? Please address:• Do overdose death rates appear to be associated with per capita income (use scatterplot)?• Do overdose death rates appear to be increasing over time…Several of the U.S. occupations that are projected to have the fastest job growth during the decade of the 2020’s are in either the medical or the renewable energy sectors of the economy. For example, the Federal Bureau of Labor Statistics (BLS) projects that “wind turbine service technicians” will be the fastest growing occupation during the decade, with an expected growth rate of 64% after 10 years. “Solar panel installers” is projected to be the third-fastest growing occupation, with an expected growth rate of 51% . Meanwhile, “nurse practitioners” ( projected growth), “occupational therapy assistants” (35% projected growth), and “home health and personal care aides” (34% projected growth) are all among the six occupations projected to grow the fastest. what was the overall percent increase in the median salary for solar panel installers after three full years? Round your answer off to the nearest whole percent.
