It is the first day of spring, and a gloomy 100-day winter has finally ended. Over those 100 days, 36 of them were clear, 24 of them were cloudy (but not rainy), and the remaining 40 were rainy. Denote the probability that a given winter day next year will be clear, cloudy, and rainy, respectively, and assume that next winter’s weather will follow the same pattern as this year’s. Please derive expressions for the maximum-likelihood estimates of Pclear, Pcloudy and...

What is the temperature on a spring day when the resistance is 216.0 Ω?
A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00 C, the resistance of the carbon resistor is 217.3 Ω. What is the temperature on a spring day when the resistance is 216.0 Ω?   Take the temperature coefficient of resistivity for carbon to be α = −5.00×10−4 C-1.

On an average winter day (3 or 38 ) in a typical house, energy already in the house is lost at the following rates: (i) 2.1 is lost through partially insulated walls and the roof by conduction; (ii) 0.3 is lost through the floor by conduction; and (iii) 1.9 is lost by conduction through the windows. Additional heating is also needed at the following rates: (iv) 2.3 to heat the air infiltrating the house through cracks, flues, and other openings...
