# A scientist has four petri dishes of different sizes. Each dish contains a different number of bacteria. Find each population density, to the nearest hundredth. Which statement is true? Dish A has the lowest population density. Dish C has the greatest population density. Dish A and Dish B have approximately the same population density. Dish C and Dish D have approximately the same population density.

Students were enquired to answer a question at school and to mention what is most important for them to succeed. Of many replies, one which that stood out was practice. Persons who definitely successful do not become successful by being born. They work hard and persistence their lives to succeeding. This is how you can get your goals. beneath some question and answer examples that you will be able to use to elevate your knowledge and gain insight that will help you to preserve your school studies.

## Question:

A scientist has four petri dishes of different sizes. Each dish contains a different number of bacteria. Find each population density, to the nearest hundredth. Which statement is true? Dish A has the lowest population density. Dish C has the greatest population density. Dish A and Dish B have approximately the same population density. Dish C and Dish D have approximately the same population density.

The statement that is True is Option D which says:

“Dish C and Dish D have approximately the same population density.”

### What is Population Density?

The population density of an area is the Number of Entities in that space/Total Area occupied by the population.

It can also be written as Dp = N/A.

Because the Dp of Dish C and Dish D is approximately 0.68, we can say that they have approximately the same Dp.

From the answer and question examples above, hopefully, they can possibly assist the student take care of the question they had been looking for and notice of the whole thing stated in the answer above. You can potentially then have a discussion with your classmate and continue the school learning by studying the subject collectively.
