Final answer:
The discard date for the dish is based on the ingredient with the earliest use-by date, which is September 1 for the beef. The scenario also includes concepts of statistical probability and checking measurements for a recipe.
Step-by-step explanation:
The subject matter presented through the example involving a chef preparing a dish with beef and pork is related to food safety and proper use-by dates. The discard date for the dish would be determined by the ingredient with the earliest use-by date, which in this case is the beef with a use-by date of September 1. Therefore, regardless of the use-by date of the pork, the dish should be discarded by September 1 to ensure food safety.
The other scenarios provided in the exercise are related to statistical probability and measurements, and they serve to practice interpretation of food-related data in a mathematical context.
Concerning Example 3.3.4.2, Marcy has 1.5 kilograms of beef available for her stew, which equals 1500 grams. Since her recipe only requires 900 grams, she certainly has enough beef for her recipe.
