Let H(x) be the percent of U. S. households with Internet use x years after 1980. Match each statement with its meaning. 1. H(23)=55
2. H(4)=k
3. H(27)≥61
4. H(17)+H(21)≈H(29)

Options-
(in the picture)

H(23)=55 - 55% of U.S households had internet use in 2003.

H(4)=k - k% of U.S households had internet use in 1984.

H(27)≥61 - At least 61 percent of U.S households had internet use in 2007.

H(17)+H(21)≈H(29) - The sum of the percents of U.S. households with internet use in 1997 and 2001 is about the same as the percent of U.S. households with internet use in 2009.
