A culture of bacteria has an initial population of 7100 bacteria and doubles every 2 hours. Using the formula P4 = Po 2 á, where P is the population after t hours, Po
is the initial population, t is the time in hours and d is the doubling time, what is the
population of bacteria in the culture after 15 hours, to the nearest whole number?

so, converting firstly the mixed fractions to improper fractions and then "adding".

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

the answer is 21%.
