- U.S. Population The number of White non-Hispanicindividuals in the U.S. civilian non-institutional population 16 years and older was 153.1 million in 2000and is projected to be 169.4 million in 2050.(Source: U.S. Census Bureau)a. Find the average annual rate of change in population during the period 2000–2050, with the appropriate units.b. Use the slope from part (a) and the population in2000 to write the equation of the line associatedwith 2000 and 2050.c. What does this model project the population to bein 2020?arrow_forwardplease do only D, E & F.arrow_forwardIn Figure 1.29, point B lies on AC between A and C. If AC = 10 and AB is 2 units longer than BC, find the length x of AB and the length y of BC.arrow_forward
- What is the input & output of RTD? O a. Temperature & Voltage Change O b. Pressure & Resistance Change O c. Temperature & Resistance Change O d. Temperature & Current Changearrow_forwardRunning Shoes. A shoe designer tests a new material for the soles of their most popular line of running shoes. She has 6 athletes run 100 miles with one of last years shoes and one of these new shoes, randomly assigning the new shoe to the left or right foot. Afterward, she measures the amount of wear on each of the shoes in millimeters. Test the claim that the amount of wear with the new material is different from the amount of wear with the old material. Runner 4 1 2 3 1.14 1.04 1.08 1.09 New Material Wear Old Material Wear 1.03 0.87 0.96 1.01 (b) Write the hypotheses in symbols. Ho: Hdiff-new-old = 0 Ha: Hdiff-new-old > 0 O Ho: Pdiff-new-old (a) Why are these paired data? O The top and bottom values in each column are from the same runner. Runners typically run in groups of two. There are an equal number of shoes of each type. This table does not have paired data; there is no clear relationship between the top and bottom values in any column. Each runner has a pair of shoes. -0 Ha:…arrow_forwardWorld Military Expenditure The following chart shows total military and arms trade expenditure from 2011–2020 (t = 1 represents 2011). †A bar graph titled "World military expenditure" has a horizontal t-axis labeled "Year since 2010" and a vertical axis labeled "$ (billions)". The bar graph has 10 bars. Each bar is associated with a label and an approximate value as listed below. 1: 1,800 billion dollars 2: 1,775 billion dollars 3: 1,750 billion dollars 4: 1,730 billion dollars 5: 1,760 billion dollars 6: 1,760 billion dollars 7: 1,850 billion dollars 8: 1,900 billion dollars 9: 1,950 billion dollars 10: 1,980 billion dollars (a) If you want to model the expenditure figures with a function of the form f(t) = at2 + bt + c, would you expect the coefficient a to be positive or negative? Why? HINT [See "Features of a Parabola" in this section.] We would expect the coefficient to be positive because the curve is concave up. We would expect the coefficient to be negative because the…arrow_forward
