- The bar graph shows the percentage of households with an interfaithmarriage in 1988 and 2012. Also shown is the percentage of households in which a person of faith is married to someone with no religion.The formula I =1/4x + 26 models the percentage of U.S. households with an interfaith marriage, I, x years after 1988.The formula N =1/4x + 6 models the percentage of U.S. households in which a person of faith is married to someone with no religion, N, x years after 1988.In which years will more than 33% of U.S. households have an interfaith marriage?arrow_forwardPlease show your complete solution.
