The tables show how many toasters two assembly lines produce in certain amounts of time. Which statement about the assembly lines is true? (6.RP.3.d)

To determine which statement about the assembly lines is true, we need to look at the production rates of both assembly line A and assembly line B as shown in the tables you've mentioned. Since I don't have the actual tables or data, I will guide you on how to compare their outputs.

1. **Compare the production rates**: Look at the number of toasters produced by both lines in the same amount of time. If Assembly line A produces more toasters than Assembly line B in the same timeframe, A has the higher output, and vice versa.

2. **Identify consistency**: Check if the output of each assembly line remains consistent in the different time periods provided in the tables. This will help you determine if one line is consistently outperforming the other.

3. **Variable output**: If you find that sometimes A has a higher output and sometimes B does, then the statement that "Sometimes assembly line A has the lower output and sometimes assembly line B has the lower output" would be true.

Once you analyze the data with these steps, you will be able to select the correct response based on the observed outputs of assembly lines A and B. If you provide the specific outputs from the tables, I could help you interpret the results directly.
