Question: Politics political scientists have discovered the following empirical rule, known as the "cube rule," which gives the relationship between the proportion of seats in the house of representatives won by democratic candidates s(x) and the proportion of popular votes x received by the democratic presidential candidate:
s(x = (x3)/(x3 + (1 - x)3) (0 ≤ x ≤ 1)
Compute s(0.6) and interpret your result.
