Question

Initially, 50 bacteria are placed in a Petri dish. It is observed that the bacteria triple in population every 8 hours.How can this information be interpreted?Select True or False for each statement.

Answer 1

The first statement will be "false" and the second one is "true". A further explanation is below.

According to the question,

Number of bacteria after "t" hours,

= $50\times (3)^{\frac{t}{8} }$

This will be false.

Now,

After 36 hours,

→ $N = 50\times (3)^{\frac{36}{8} }$

       $= 50\times (3)^{\frac{36}{8} }$

       $= 50\times (3)^{4.5}$

       $= 7015$

This will be true.
