i have this table:

day -- change in temperature
mon -12 degree fahrenheight
tues +6 degree f
wed -4 degree f
thur -9 degree f
fri +8 degree f

question: which two day period had the greatest change in temperature?
i said : mon to tues and
thurs to friday is that right or are they asking for just 1 answer im confused

There can only be one "greatest." 18 > 17.

To determine the two-day period with the greatest change in temperature, you need to calculate the temperature differences between consecutive days and compare them. Based on the given table, you correctly identified two possible periods:

1. Monday to Tuesday: The change in temperature is +6°F - (-12°F) = 18°F.
2. Thursday to Friday: The change in temperature is +8°F - (-9°F) = 17°F.

Both of these periods have significant temperature differences. However, to be sure which one is the greatest, you should compare them directly. In this case, you can say that the two-day period with the greatest change in temperature is Monday to Tuesday, with a temperature difference of 18°F.

Therefore, your answer of Monday to Tuesday is correct.
