Answer:

6*10^8  is 200 times larger than  3*10^6

Step-by-step explanation:

6*10^8\ and \ 3*10^6

To compare both values we divide the exponents

\frac{6*10^8}{3*10^6}

6 divide by 3 is 2

for simplify exponents we use exponential property

a^m / a^n = a^(m-n)

\frac{10^8}{10^6}=10^2

\frac{6*10^8}{3*10^6}=2*10^2= 200

6*10^8  is 200 times larger than  3*10^6

Answer:

A. principal interviewed the 25 students who scored highest on a reading test.

D. For a report on the exercise habits of adults, Sergio talked to 30 adults at a local fitness center.

E. Josh asked the first 25 people he met at the dog park if they preferred dogs or cats.

Step-by-step explanation:

Biased means if the selection of every unit does not have an equal chance of being selected in a sample.

The sample is said to be good if choosing the unit is unbiased. The sample is said to be unbiased if the selection of each unit is independent.

Option A is an example of data selected in a biased way because principal chose only those student who scored the highest marks on reading test.

Options B and C are unbiased as here a selection of each number and name of the student has an equal chance of being selected.

Option D is biased because Sergio talked adults at a local fitness center where people go for maintaining their health. So, there is a chance of the selection of fitted adults more than unfitted adults.

Option E is biased because Josh met people at the dog park where dog lovers are more than a cat lover.
