1 0.9
2 1.0
3 0.8
4 1.2
5 0.9
Rita wants to know the average weight of each apple in an 8-pound bag of apples. She purchased 5 bags and found the average apple weight. Using her results, an apple from an 8-pound bag of apples should weigh between:
A. 0 lbs and 0.9 lb
B. 1.0 lb and 1.2 lbs
C. 0.8 lb and 1.2 lbs
D. 0.8 lb and 0.9 lb
Answer (2)
Identify the minimum average apple weight from the given data: 0.8 lbs.
Identify the maximum average apple weight from the given data: 1.2 lbs.
Determine that the weight range for an apple from an 8-pound bag is between the minimum and maximum average weights.
Conclude that an apple from an 8-pound bag should weigh between 0.8 lbs and 1.2 lbs .
Explanation
Understanding the Problem Rita wants to estimate the weight range of apples in an 8-pound bag. She has data on the average apple weight from 5 different bags. We need to find the minimum and maximum average apple weights from the given data to determine the range.
Listing the Data The average apple weights from the 5 bags are: Bag 1: 0.9 lbs/apple Bag 2: 1.0 lbs/apple Bag 3: 0.8 lbs/apple Bag 4: 1.2 lbs/apple Bag 5: 0.9 lbs/apple
Finding the Minimum Weight To find the minimum average apple weight, we compare the weights: 0.9, 1.0, 0.8, 1.2, and 0.9. The smallest value is 0.8.
Finding the Maximum Weight To find the maximum average apple weight, we compare the weights: 0.9, 1.0, 0.8, 1.2, and 0.9. The largest value is 1.2.
Determining the Weight Range Therefore, an apple from an 8-pound bag of apples should weigh between 0.8 lbs and 1.2 lbs based on Rita's results.
Examples
Understanding the range of apple weights can be useful in various real-life scenarios. For example, if you are a farmer selling apples, knowing the average weight range helps in pricing your bags. If you are a consumer, it helps in estimating how many apples you might get in a bag of a certain weight. This concept of finding minimum and maximum values is also applicable in other areas like tracking temperature variations, stock prices, or even sports statistics to understand performance ranges.
The average weight of an apple from Rita's previous bags ranges from 0.8 lbs to 1.2 lbs. Therefore, an apple from an 8-pound bag of apples should weigh between 0.8 lbs and 1.2 lbs. The correct answer is option C: 0.8 lb and 1.2 lb.
