According to ecology writer Jacqueline Killeen, phosphates contained in household detergents pass right through their sewer systems, causing lakes to turn into swamps that eventually dry up into desserts. The following data (Table A) show the amount of phosphates per load of laundry, in grams, for a random sample of various types of detergents used according to the prescribed directions. For the given phosphate data, find the mean. * (2 Points) Laundry Detergent A&P Blue Sail Dash Concentrated All Cold Water All Breeze Phosphates per Load (grams) 49 47 43 43 41

Basic Concepts of Water Resource Sustainability

The majority of the earth's surface is composed of water. The water which is available for use by the living beings on earth comes from various water resources. Water resources are the naturally occurring water bodies that are intended to be used by the living beings on earth for drinking and other uses. Water resources provide 3% as freshwater, 97% as saltwater, two-thirds of which are frozen as glaciers and ices. The remaining water which generally doesn't remain frozen are the water resources found underground, precisely known as groundwater. The majority of these water sources act as non-convention sources of power generation, like in hydropower stations.
