Joseph measures the ropes used to tie boats to a dock. He records the lengths of the ropes in feet and then makes a line plot.

Question

A line plot named

Joseph concludes that the difference between the longest and shortest lengths is

Marta disagrees and says that there is no difference. Who is correct?

at the greatest and least lengths.

Answer 1

Marta is correct because there is no difference between the greatest and least lengths represented by the line plot. The line plot only shows the number of times each length appears, not the actual values of the lengths themselves. Therefore, it is not possible to determine the difference between the longest and shortest lengths from the line plot alone.

Answer 2

There 2nd drop down menew tells me to add or subtract
witch one do I choose

Answer 3

Based on the question and the information provided, you should choose "neither" for the second drop-down menu. The question is asking about the difference between the longest and shortest lengths, but the line plot only shows the frequency of lengths and not the actual values of the lengths. Therefore, it is not possible to add or subtract anything from the line plot to determine the difference between the longest and shortest lengths.

Answer 4

no I need to choose add or subtract I can't choose neither
so witch one do I choose

Answer 5

If you must choose between adding or subtracting, you would choose "subtract". However, please note that subtracting is not a correct method for finding the answer to this question since the line plot only shows the frequency of lengths and not the actual values of the lengths. Therefore, subtracting based on the line plot would not provide accurate or meaningful results.
