(b) Write down the formula for the function g(t) which is obtained by shifting f(t) t 4 units to the right. (c) Determine the derivative function g'(t) and sketch the graph of g'(t) on the interval (0, 52). Show any important points on the graph.

Suppose that you work for the conservation of natural areas at the Bureau of Land Management. Your section concerns the effect of wildfires on natural areas. Your supervisor asked you to analyze the temporal trend in wildfires. In particular, she is interested in the following associations:1. Has the number of wildfires per year increased?2. Has the total burned area (in acre) per year increased?3. Has the burned area (in acre) per fire increased?The accompanied data file contains the number of wildfires, total burned area, and burned area per fire in the U.S. from 2000 to 2019. Question 1. Using Excel, create three scatter plots which show each association (year and number of wildfires, year and total burned area, and year and burned area per fire). Clearly label the graphs. Note that year should be on the x-axis. Attach the scatterplot to this report. Refer to the textbook 12.2. (15 pts.) Question 2. Using the scatter plots created in Question 1, perform a visual assessments.…

Based on the coefficient of determination you calculated in Question 3, what percentage in the variability in the dependent variable is explained by year? Refer to the textbook 12.3. (10 pts.)
A) What is the purpose of the “callout bubble” in the bottom right-hand corner of the graph, showing a tiny red square inside the yellow square? Why do you suppose the author felt the need to use a callout bubble? B) Data from this source show that the rate of symptomatic infection with COVID for people who have been vaccinated is about 100 infections per 102,000 vaccinations. As of July 30, 2021, data show that164,000,000 Americans have been fully vaccinated. How many of these vaccinated Americans would be expected to become infected with COVID and display symptoms? C) Data from this source show that the rate of death from COVID for people who have been vaccinated is about 1 death per 102,000 vaccinations. As of July 30, 2021, data show that 164,000,000 Americans have been fully vaccinated. How many of these vaccinated Americans would be expected to die from COVID?
This question is from the textbook and I had raised a request as the graph was not visible in your solution. The Cambridge Study in Delinquent Development was under-taken in north London to investigate the links between criminal behavior in young men and the socioeconomic factors of their upbringing. A cohort of 395 boys was followed for about 20 years, starting at the age of 8 or 9. The following table shows the total number of criminal convictions by the boys between the start and end of the study. Number of convictions Frequency 0 265 1 49 2 21 3 19 4 10 5 10 6 2 7 2 8 4 9 2 10 1 11 4 12 3 13 1 14 2 a) Display the frequency distribution in a graph. Which type of graph is most appropriate? (b) Describe the shape of the frequency distribution. Is it skewed or is it symmetric? If skewed, is it positively skewed or negatively skewed? Is it unimodal or bimodal? Are there outliers in the…
At the beginning of 2020, the trends described below were predicted to be the major HR trends for 2020. After reading these trends, which two trends do you see as now relevant for 2022 and why? Given the unprecedented two years we’ve had due to COVID, do you see any of these trends as now irrelevant?
In a poll, a random sample of 2163 adults aged 18 and over was asked, “When you see an ad emphasizing that a product is made in your country, are you likely to buy it, less likely to buy it, or neither more nor less likely to buy it?”. The results of the survey are presented in the side by side graph.
Mercury is a persistent and dispersive environmental contaminantfound in many ecosystems around the world.When released as an industrial by-product, it often finds itsway into aquatic systems where it can have deleteriouseffects on various avian and aquatic species.

Swordfish have a unique "heater organ" that maintains elevated eye and brain temperatures when hunting in deep, cold water. The following graph illustrates the results of a study by Fritsches et al. (2005) that measured how the ability of swordfish retinas to detect rapid motion, measured by the flicker fusion frequency, changes with eye temperature. 50 40- 30- 20 10- 0. 10 15 20 25 Eye temperature ("C) Whitlock & Schluter, The Analysis of Biologica Deta Se 2020 W.H. Freeman and Company The 20 points in the graph were obtained from measurements of 6 swordfish. Can you treat the 20 measurements as a random sample? No, because the selection of the measurements is not independent. Yes, because otherwise the results would not be published. Yes, because the researchers can make a scatter plot only based on the random sample. ONo, because the researchers should have studied at least 10 swordfish. Flicker fusion frequency (hertz)

Twins Twins are often born after a pregnancy that lastsless than 9 months. On the next page is a graph from theJournal of the American Medical Association (JAMA)showing the rate of preterm twin births in the United States over the past 20 years. In this study, JAMA catego-rized mothers by the level of prenatal medical care they received: inadequate, adequate, or intensive.a) Describe the overall trend in preterm twin births. b) Describe any differences you see in this trend, depend-ing on the level of prenatal medical care the mother received.c) Should expectant mothers be advised to cut back onthe level of medical care they seek in the hope ofavoiding preterm births?
