Final answer:
The student's question requires a specific percentage of the noncommercial foodservice industry, which is not provided. In lieu of this, examples were given on calculating percentages in other contexts such as in a university cafeteria for veggie-burgers and beliefs in alien landings among the adult US population.
Step-by-step explanation:
The noncommercial segment of the foodservice industry refers to operations serving food as a secondary activity and not for profit. Examples include schools, hospitals, and company cafeterias. The question seems to be seeking a specific percentage that represents the noncommercial segment, but the question does not provide a specific number.
Nonetheless, to illustrate the process for similar problems, consider the scenario mentioned in the question about a university cafeteria. If out of 889,875 burgers, 997 were soybean-vegetable burgers, then the fraction representing veggie-burgers is 997/889,875. To convert this fraction into a percentage, you would divide 997 by 889,875 and then multiply the result by 100, giving you approximately 0.112%.
Another example provided in the question touches on population-based percentages. If 36 percent of adult Americans believed in alien landings as per a 2012 poll and there were about 222,000,000 adults, using scientific notation to find the number of believers would entail calculating 36% of 2.22 x 108, which gives 7.992 x 107 adults.
