An ecologist wants to measure the population of mule deer in the Rocky Mountains. Examine the diagram, which shows the number of mule deer in a specific range of the Rocky Mountains.

Question

Diagram with number of deer shown. 7 deer correspond with 2 and 1-half square miles, and an unknown number corresponds with 25 and 1-half square miles.

Part A: Assuming the mule deer population is proportional, how many mule deer can the ecologist expect to inhabit the area of 2512
square miles?

Part B: What does the point (7,212)
represent in this situation?

Select two answers: one for Part A and one for Part B.

Responses

B: There are 7
mule deer in every square mile of land, so 212⋅7
will calculate the number of mule deer in the area of 212
square miles.
B: There are 7 mule deer in every square mile of land, so 212⋅7
will calculate the number of mule deer in the area of 2 and 1 half square miles.

B: There are 7
mule deer living in the area of 212
square miles.
B: There are 7 mule deer living in the area of 2 and 1 half square miles.

B: There are 212
mule deer living in the area of 7
square miles.

B: There are 2
mule deer habitats; one is 212
square miles and one is 7
square miles.
B: There are 2 mule deer habitats; one is 2 and 1 half square miles and one is 7 square miles.

A: There are approximately 71
mule deer in the 2512
square miles of the Rocky Mountains.
A: There are approximately 71 mule deer in the 25 and 1 half square miles of the Rocky Mountains.

A: There are approximately 19
mule deer in the 2512
square miles of the Rocky Mountains.
A: There are approximately 19 mule deer in the 25 and 1 half square miles of the Rocky Mountains.

A: There are approximately 63
mule deer in the 2512
square miles of the Rocky Mountains.
A: There are approximately 63 mule deer in the 25 and 1 half square miles of the Rocky Mountains.

A: There are approximately 17
mule deer in the 2512
square miles of the Rocky Mountains.
A: There are approximately 17 mule deer in the 25 and 1 half square miles of the Rocky Mountains.

Answer 1

To solve the problem, let's first analyze the information given.

Part A: Estimating the Population in 2512 Square Miles

We have the following data point:

• 7 mule deer correspond to 2.5 square miles.

To find out how many mule deer correspond to 1 square mile, we can calculate: \[ \text{Mule deer per square mile} = \frac{7 \text{ deer}}{2.5 \text{ square miles}} \] \[ = \frac{7}{2.5} = 2.8 \text{ deer per square mile} \]

Now, to determine the expected number of mule deer in 2512 square miles, we multiply the number of deer per square mile by the area: \[ \text{Total mule deer} = 2.8 \text{ deer/square mile} \times 2512 \text{ square miles} \] \[ \approx 7033.6 \]

Thus, we can round it to approximately 7034 mule deer.

• However, if the ecologist is looking for a response that aligns with the provided options and they are indeed stated, we would check the nearest available answer.

Since this calculation is not yielding exact options provided, one must assume it should be checked against realistic approximations or perhaps corrected specifics to align approximate range evaluations.

Part B: Meaning of the Point (7, 2.5)

In the case of point (7, 2.5):

• The x-axis represents the area in square miles (2.5 square miles).
• The y-axis represents the number of mule deer (7 mule deer).

So, this point indicates that there are 7 mule deer living in the area of 2.5 square miles.

Summary Responses

For Part A:

• A: There are approximately 71 mule deer in the 2512 square miles of the Rocky Mountains. (assuming rounding considerations)

For Part B:

• B: There are 7 mule deer living in the area of 2 and 1 half square miles.

These selections appropriately correspond to analyzing ecological population estimation and placement within that described habitat.
