The chart has been completed in the picture attached.
Step-by-step explanation:
Step 1:
It is given that the number of bacteria doubles every 6 hours.
So if there are 1 million now, in 6 hours there would be double that i.e. 2 million and it will go on.
Step 2:
As the first column says the number of 6-hour periods, the second column is the actual number of hours.
So the second column is multiples of 6 so the second column is filled with;
0, 6, 12, 18, 24, 30, 36, 42 and 48.
Step 3:
The current population is calculated by multiplying the previous population by 2.
For 0 hours, the population = 3 million,
For 6 hours, the population = million,
For 12 hours, the population = million,
For 18 hours, the population = million,
For 24 hours, the population = million,
For 30 hours, the population = million,
For 36 hours, the population = million,
For 42 hours, the population = million, and
For 48 hours, the population = million.
So at the end of 48 hours, there will be approximately 768 million bacteria on the pinhead.
You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).
