Final answer:
The mean weight of a package of apples can be found by adding up the weights of individual apples and dividing by the total number of apples in the package.
Step-by-step explanation:
To find the mean weight of a package of apples, we need to sum up the weights of individual apples and divide it by the total number of apples in the package. Since there are 4 apples in a package, we add up the weights of all 4 apples and then divide by 4. Let's say the weights of the 4 apples are 50 grams, 60 grams, 70 grams, and 80 grams. Adding them up gives us 50 + 60 + 70 + 80 = 260 grams. Dividing by 4 gives us a mean weight of 260/4 = 65 grams. Therefore, the mean weight of a package of apples is 65 grams.
