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
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.

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.
