Question

The graph shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment.
Based on the graph, what is the approximate number of bacteria after 16 hours?
6 bacteria
8 bacteria
60 bacteria
80 bacteria

Answer 1

Answer:

The approximate number of bacteria after 16 hours is  

60

Step-by-step explanation:

The values on the x-axis indicates the time.

Between 10 hours and 20 hours, there are 3 boxes.

This means that each box is

So can estimate 16 hours from the graph to be between the first and second box after 10 hours (see graph for the position).

We now trace to the y-axis to determine the corresponding number of bacteria.

This gives us the number of bacteria to be

The correct answer is C.

Answer 2

The figure shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment.

Now we have to find the number of bacteria after 16 hours.

From the graph , the graph seems to rise in y direction in the mid way between 10 and 20 .

The y coordinate in the mid way between 10 and 20 is approximately 80.

So we can say that the number of bacteria after 16 hours is 80.

Answer : last option that is 80 bacteria.
