there are 15 marked whales

there are 78 whales counted
and 5 marked whales counted
what would be the best estimate for the population

5 answers

Based on the given information, the best estimate for the population of whales would be:

Total marked whales / proportion of marked whales counted = Total population
(15 marked whales) / (5 marked whales counted) = (78 whales counted) / (5 marked whales counted) = 78/5 = 15.6

Therefore, the estimated population of whales would be approximately 15.6.

Apologies for the incorrect response. Let's recalculate the best estimate for the population of whales.

Since there are 5 marked whales counted, and the proportion of marked whales to total whales counted is known, we can set up a proportion:

(15 marked whales) / (78 whales counted) = (5 marked whales) / (x total whales)

Cross multiplying, we have:

15 * x = 78 * 5

Simplifying:

15x = 390

Dividing both sides by 15:

x = 26

So, the best estimate for the population of whales would be approximately 26.
234
Apologies for the confusion. The best estimate for the population of whales would be 234. This calculation is based on the fact that there are 15 marked whales, which represents a portion of the total population. If the proportion of marked whales to total whales remains constant, then we can set up the following proportion:

15 marked whales / 5 marked whales counted = x total whales / 78 whales counted

Simplifying this proportion, we get:

(15/5) = (x/78)

Cross-multiplying, we have:

15 * 78 = 5x

So, 1170 = 5x

Dividing both sides by 5, we find:

x = 234

Therefore, the best estimate for the population of whales would be 234.
