Let's calculate the answers to each part of the question:
(a) How many Maine voters turned out to vote in the 2004 presidential election?
In 2004, Maine had 664,000 voters, and the voter turnout decreased by 0.9% (0.009 as a decimal).
Number of voters in 2004 = 664,000 - (0.009 * 664,000)
Number of voters in 2004 = 664,000 - 5,976
Number of voters in 2004 = 658,024 voters
So, 658,024 Maine voters turned out to vote in the 2004 presidential election.
(b) How many people in Arizona voted in the 2004 election?
In 2004, Arizona had 1,632,000 voters.
So, 1,632,000 people in Arizona voted in the 2004 election.
(c) How many more people voted in the 2000 election than in the 2004 election in the state of Alaska?
In 2000, Alaska had 280,000 voters, and the voter turnout decreased by 12.4% (0.124 as a decimal) in 2004.
Number of voters in 2004 = 280,000 - (0.124 * 280,000)
Number of voters in 2004 = 280,000 - 34,720
Number of voters in 2004 = 245,280 voters
Now, we can find how many more people voted in the 2000 election than in the 2004 election in Alaska:
Difference = Number of voters in 2000 - Number of voters in 2004
Difference = 280,000 - 245,280
Difference = 34,720 more people voted in the 2000 election than in the 2004 election in Alaska.
