Estella is a marine biologist observing the location of a rare species of sea anemone. She records the depth, in feet, of two sea anemones. A research center sends data about where it observed two more sea anemones, but the units for depth given are in fathoms. A fathom is a unit of length used in reference to depth of water. Estella knows that 5 fathoms is equivalent to 30 feet. The table below shows the depths of four sea anemones.
