If interest is compounded annually, what is the amount of money alter 8 years? $ (Do not round until the nal answer, Then round to the nearest cent as needed) What is the purchasing power of $1 in 1987 in terms of 2019 dollars? Average Annual Consumer Price Index (CPI) (1982 - 1984 = 100) Year CPI Year CPI Year CPI The purchasing power of $1 in 1987 in terms of 2019 dollars is $. 198 90.9 1995 152.4 2009 214.5 (Round to the nearest cent as needed.) 1982 96.5 1996 156.9 2010 218.1 1983 99.6 1997 160.5 2011 224.9 1984 103.9 1998 163.0 2012 229.6 1985 107.6 1999 166.6 2013 233.0 1986 109.6 2000 172.2 2014 236.7 1987 113.6 2001 177.1 2015 237.0 1988 118.3 2002 179.9 2016 240.0 1989 124.0 2003 184.0 2017 245.1 1990 130.7 2004 188.9 2018 251.1 1991 136.2 2005 195.3 2019 255.7 1992 140.3 2006 201.6 2020 258.8 1993 144.5 2007 207.3 1994 148.2 2008 215.3Sampling techniques can be used to estimate physical quantities, To estimate a large quantity, you might measure a representative small sample and nd the total quantity by "scaling up," To estimate a What is a good method for estimating the thickness of each coin? ' a A. Take one of each cein and make a stack. Measure the height, and then divide the height of the stack by the number of coins in the stack. ' * B. Stack some coins to a measureable height such as 2 inches, and then divide the height of the stack by the number of coins in the stack. Do this for each type of coin. ' a C. Stack some coins to a measureable height such as 2 inches, and then divide the height of the stack by the number of coins in the stack. The thickness of the rest of the coins is about half of this quotient, - :3 D. Stack some coins to a measureable height such as 2 inches, and then murtiply the height of the stack by the number of coins in the stack, Do this for each type of coin, How thick is a penny? A penny is mm thick. (Round to one decimal place as needed) How thick is a nickel? A nickel is mm thick, (Round to one decimal place as needed) How thick is a dime'? A dime is mm thick, (Round to one decimal place as needed) Sampling techniques can be used to estimate physical quantities. To estimate a large quantity, you might measure a representative small sample and nd the total quantity by "scaling up." To estimate a tl (Round to one decimal place as needed) How thick is a nickel? A nickel is mm thick. (Round to one decimal place as needed.) How thick is a dime? A dime is mm thick. (Round to one decimal place as needed.) How thick is a quarter? A quarter is mm thick. (Round to one decimal place as needed.) Would you rather have your height stacked in pennies, nickels, dimes, or quarters? '- A. Nickels; they are the thickest, so I won't have to use as many. B. Dimes; they are the thickest, so I won't have to use as many. Also, they are smaller overall, so the pile won't be hard to clean up. '- C. Quarters; the stack of quarters in my height will have a lot of value. Also, they are thick' so I won't have to use as many as I would ifl chose pennies or dimes. 7 D. Pennies; they are difficult to come across, so the stack of pennies will have a great value
