A so-called 7-way lamp has three 60-watt bulbs which may be turned on one or two or all three at a time, and a large bulb which may be turned to 100 watts, 200 watts or 300 watts. How many different light intensities can the lamp be set to give if the completely off position is not included? (The answer is not 7.)

You have an LED night light without a photocell control with the following information: It draws 0.3 Watts continuously. It is always on--24 hours per day. Based on this information, we can now calculate the energy used by this nightlight in one year. For this problem we will assume a year to consist of 365 days. (It is not a leap year.) Calculate the energy used by this night light in one year. Group of answer choices 0.1095 kW-hrs 0.365 kW-hrs 0.003 kW-hrs 2.628 kW-hrs
