Question by jay: The Sanchez household is about to install solar panels to reduce the cost of heating their house. ?
In order to know how much the solar panels help, they record their consumption of natural gas before the panels are installed. Gas consumption is higher in cold weather, so the relationship between outside temperature and gas consumption is important. Here are data for 12 consecutive months:
Degree days193300081127463834
Gas used3221.610.70.71.63.15.17.776.1
Use your calculator or software: the correlation between degree days and overall gas usd is about
(Use decimal notation. Give your answer to three decimal places.)
What are the values [...]

Best answer:
Answer by ScottLewisSolar energy is a term for describing a range of methods for obtaining energy from the sun. Many people immediately think about solar panels when hearing solar energy but wind, biomass and hydropower are all forms of solar energy. Wind develops through highs and lows in temperature. Wind drives waves. Rainfall, created by sun-warmed evaporated water feeds the rivers that are sources for hydropower. [...]
