if there are a total of 10 marked whales, a total of 89 whales counted, and a total of 8 marked whales counted. what is the best estimate for the population of whales

Answer 1

To find the best estimate for the population of whales, we can use the concept of proportion. We know that 8 marked whales represent a total of 10 marked whales in the population.

So, if 8 whales represent 10 in the population, then 89 whales would represent how many in the population?

Using a proportion:

8 marked whales / 10 marked whales = 89 counted whales / x

Cross-multiplying:

8x = 10 * 89

8x = 890

Dividing both sides by 8:

x = 890 / 8

x ≈ 111.25

Therefore, the best estimate for the population of whales would be around 111.

Answer 3

I apologize for any confusion caused. If there are 8 marked whales out of a total of 89 counted whales, we can set up a proportion to estimate the population of whales.

8 marked whales / 10 marked whales = 89 counted whales / x (population of whales)

Cross-multiplying:

8x = 10 * 89

8x = 890

Dividing both sides by 8:

x = 890 / 8

x = 111.25

Therefore, the best estimate for the population of whales would be approximately 111.

Answer 5

If there are 8 marked whales out of a total of 89 counted whales, we can set up a proportion to estimate the population of whales.

8 marked whales / 10 marked whales = 89 counted whales / x (population of whales)

Cross-multiplying:

8x = 10 * 89

8x = 890

Dividing both sides by 8:

x = 890 / 8

x = 111.25

Therefore, the best estimate for the population of whales would be approximately 111.
