Question

which month had the greatest decrease in temperature from the previous month? average daily low temperatures chart with months jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec and their average daily low temperatures (in degrees fahrenheit): jan -19.6, feb -23.3, mar -20.5, apr -9.9, may 14.8, jun 29.9, jul 32.1, aug 33.2, sep 26.4, oct 9.5, nov -7.2, dec -10.2
______ had the greatest decrease in temperature.

Explanation:

Step1: Calculate temperature change for each month

• Jan to Feb: \(-23.3 - (-19.6) = -3.7\)
• Feb to Mar: \(-20.5 - (-23.3) = 2.8\)
• Mar to Apr: \(-9.9 - (-20.5) = 10.6\)
• Apr to May: \(14.8 - (-9.9) = 24.7\)
• May to Jun: \(29.9 - 14.8 = 15.1\)
• Jun to Jul: \(32.1 - 29.9 = 2.2\)
• Jul to Aug: \(33.2 - 32.1 = 1.1\)
• Aug to Sep: \(26.4 - 33.2 = -6.8\)
• Sep to Oct: \(9.5 - 26.4 = -16.9\)
• Oct to Nov: \(-7.2 - 9.5 = -16.7\)
• Nov to Dec: \(-10.2 - (-7.2) = -3\)

Step2: Identify the largest decrease (most negative change)

The change from Sep to Oct is \(-16.9\), which is the most negative (largest decrease) among all calculated changes.

Answer:

October
