11. Mark and Kandace worked together in Earth Systems to measure the weather for several days in a row. They collected the following data:

Mon. / Tues. / Wed. / Thurs. / Fri.
Temp. (ºC) / 5 / 11 / 12 / 12 / 13
Cloud cover / 70% Altostratus / 90% Nimbostratus / 25% Stratus / 20% mix stratus/stratocumulus / 25% stratocumulus
Pressure (mb) / 1012 / 1010 / 1019 / 1023 / 1025
Precip. (in) / 0.00 / 0.05 / 0.01 / 0.00 / 0.00
