3 A population of single-celled organisms was grown in a Petri dish over a period of 16 hours. The number of organisms at a given time is recorded in the table below. Time, hrs Number of Organisms (x) (y) 25 0 2 36 4 52 6 68 8 00 85 10 104 12 142 16 260 Determine the exponential regression equation model for these data, rounding all values to the nearest ten-thousandth. Using this equation. predict the number of single-celled organisms, to the nearest whole number, at the end of the 18th hour.
