Water from a certain pond contains an average of 4.9 specimens of species Z per cubic centimeter. How many specimens of species Z are contained in 1 cubic millimeter of pond water? [1 cubic centimeter = 1000 cubic millimeters]
Explanation
Express 4.9 in scientific notation: \( 4.9 \times 100\). To convert this number from cubic centimeters to cubic millimeters, divide by 1000. To accomplish this in scientific notation, subtract 3 from the exponent: \(4.9 \times 10^{-3}\)
