Marriage. Table 5 shows the marriage and divorce rates per 1 , 000 population for selected years since 1960 . (A) Let x represent the number of years since 1960 and find a cubic regression polynomial for the marriage rate. (B) Use the polynomial model from part (A) to estimate the marriage rate (to one decimal place) for 2025 .
