Lucy wants to find out the number of frogs in the pond near her house she catches 54 of them puts on a leg bands on each frog and put them back in the pond the next week she catches 70 frogs of those 70 frogs 13 have a leg band based on this information what is a responsible estimate of the number of frogs in the pond?

I'll be glad to check your answer.

so the answer is...

The answer is (D:111 )

The answer is C) 291. 70/13=5.38

5.38*54=290.5
Round up to 291
My son had this on quizzes we thought it was 111 but the correct answer was 291

In a sample of 50 museum visitors one afternoon, 22 were female and 28 were male. If there were 800 museum visitors that afternoon, estimate the number of visitors who were female.

To estimate the number of visitors who were female, we can use proportions. We know that 22 out of 50 visitors were female, which is 22/50 or 44% of the sample. We can assume that the same percentage of the total visitors were female. So to estimate the number of female visitors out of the total 800, we can set up a proportion:

44/100 = x/800

To solve for x, we can cross-multiply:

100x = 44 * 800
x = 35.2 * 8
x ≈ 282

So we can estimate that there were approximately 282 female visitors out of the total 800.

To find a responsible estimate of the number of frogs in the pond, we can use a proportion.

Let's set up the proportion:

(54 frogs with leg bands) / (total number of frogs) = (13 frogs with leg bands) / (70 total frogs)

To find the total number of frogs, we can cross multiply:

54 * 70 = 13 * total number of frogs

3780 = 13 * total number of frogs

Now, we need to solve for the total number of frogs. We divide both sides of the equation by 13:

total number of frogs = 3780 / 13

total number of frogs ≈ 291.54

Since we can't have a fraction of a frog, we can round this estimate to the nearest whole number.

Therefore, a responsible estimate of the number of frogs in the pond is 291.

So, the answer is C) 291.
