Final answer:
The weight of 2 apples is not directly provided but can be estimated from the average weight of an apple. If an average apple weighs around 0.5 lb, then 2 apples would weigh about 1 lb or 16 ounces.
Step-by-step explanation:
To find the weight of 2 apples, we need to use the information about the average weight of a bag of apples. Since it's mentioned that the average weight of a bag of apples is 5.1 lb with a percent uncertainty of 6%, we need to calculate the individual weight of an apple from this. Then, multiply that value by 2 to get the weight of two apples.
First, we start by confirming the average weight of a single apple. The average weight can be estimated by dividing the total weight by the assumed number of apples in the bag. For instance, if the bag contains approximately 10 apples, each apple would on average weigh 0.51 lb. However, it's not specified how many apples are in a 5.1 lb bag, so we will consider the average apple weight to be around 0.5 lb for this calculation.
Therefore, the weight of 2 apples would be 0.5 lb multiplied by 2, resulting in 1 lb or 16 ounces.
