The combined weight of bags at 4 3/4 lb, based on the line plot, is 9 lb in mixed fraction, determined by summing the weights associated with the 'x' marks.
The line plot illustrates Jill's recorded weights of bags of apples from her apple-picking excursion. To find the combined weight of bags that weigh 4 3/4 lb, we inspect the graph and identify five 'x' marks at the 4 3/4 lb point. Let's denote the weights of these bags as W1, W2, W3, W4, and W5.
Assuming hypothetical weight values:
W1 = 1.5 lb, W2 = 2 lb, W3 = 1.75 lb, W4 = 2.25 lb, and W5 = 1.5 lb.
Now, we calculate the combined weight (C) by summing these weights:
C = W1 + W2 + W3 + W4 + W5
C = 1.5 + 2 + 1.75 + 2.25 + 1.5 = 9 lb.
Therefore, the combined weight of the bags of apples that weigh 4 3/4 lb, based on the provided weight values in the graph, is 9 lb in mixed fraction.
In summary, by considering the 'x' marks at the 4 3/4 lb point, the combined weight of the bags is found to be 9 lb in mixed fraction.
