Final answer:
To determine the U.S. population based on the proportionality of area and population, set up a proportion using the areas and populations of California and the U.S. Solve for the U.S. population by cross multiplying and dividing. The U.S. population is approximately 8.824×10^8 people.
Step-by-step explanation:
To determine the population of the U.S. based on the proportionality of area and population, we can set up a proportion using the geographic areas of California and the U.S. and the population of California:
(Population of California) / (Area of California) = (Population of U.S.) / (Area of U.S.)
Substituting the given values, we have:
(3.804×10^7) / (1.637×10^5) = (Population of U.S.) / (3.794×10^6)
Cross multiplying and solving for the population of the U.S., we get:
(Population of U.S.) = (3.804×10^7) / (1.637×10^5) * (3.794×10^6)
Calculating the expression on the right-hand side, we find that the population of the U.S. is approximately 8.824×10^8 people.
