The figure below shows a particle's distance from a point as a function of time, t. What is the particle's average velocity from t = 0 tot = 3? distance (meters) s(t) 3 1 t (sec) 2 Round your answer to the nearest integer. The particle's average velocity from t = 0 tot = 3 is i meter(s)/sec.
Question: a. Sales of the Flying Flintmobile has been increasing over the past five years. The operations manager has estimated sales in 2017 to be 410 Flying Flintmobiles. Using exponential smoothing with a weight of a = 0.30, develop forecasts for 2017 through 2022. Year Sales Forecast 2016 450 2017 495 2018 518 2019 563 2021 584 2022 (i) Advise Flying Flintmobile of the benefits associated with this method of forecasting. (ii) Caution the manager on the limitations associated with your forecast.
FARM POPULATION Consider the percent of the United States population which lived on farms during the years 1880-1990. Year Percent 1880 43.8% 1890 42.3% 1900 41.9% 1910 34.9% 1920 3.1% 1930 24.9% 1940 23.2% 1950 15.3% 1960 8.7% 1970 4.8% 1980 2.7% 1990 1.9% 1. Using technology, calculate the average rate of change per year. You may, for example, make a table in a spreadsheet with Year, Percent of Population, and Average Rate of Change, as three columns. What are the independent and independent variables? 2. Using technology, create a plot of Percentage vs Year. Does the data appear to be linear? Explain. 3. Using technology, construct a linear trendline and determine the R2 value. What is the trendline equation? What is the slope, including units? What is the R2 value? Is there a strong or weak correlation? 4. Using the trendline formula, calculate algebraically the date when 100% of the population lived on a farm? Explain in the context of the problem. 5. Using the trendline…
Carbon foot print: Carbon dioxide (CO, is produced by burning fossil fuels such as oil and natural gas, and has been connected to global warming. The following table presents the average amounts (in metric tons) of CO, emissions for certain years per person in the United States and per person in the rest of the world.

An entrepreneur who owns and operates two businesses (A and B) would like to analyze their profitability. They would like your help in the analysis. They give you the annual net profit (in thousands of $) for each business from 2008-2020.

Suppose you want to graph the distribution of profits. Explain why using only one stem- plot might not be optimal for the analysis. b. Describe the correct stemplot to use. Generate this stemplot. Explain your steps. What can you say about the distribution from this stemplot? c. When are stemplots useful? And why is that? d. Suppose that instead of having 26 observations you have 200 observations. What graph should you generate? e. What other type of…
