(A) Let x represent the number of years since 1960 and find a cubic regression polynomial for the marriage rate. y = ( x3 + ( ) x2 + ( (Round to six decimal places as needed.) (B) Use the polynomial model from part (A) to estimate the marriage rate for 2023. The value of x that corresponds to 2023 is x = . The estimated marriage rate in 2023 will be about per 1,000 population. (Round to the nearest tenth as needed.)The table to the right shows the marriage and divorce rates per 1,000 population for selected years since 1960. Complete parts (A) and (B) Marriages and below. Divorces (per 1,000 population) Date Marriages Divorces 1960 7.6 2.2 1970 11.4 3.5 1980 10.3 5.2 1990 9.4 4.7 2000 9.1 4.1 2010 6.8 3.6
