In​ 2015, there were approximately 3,805,000 births in a country. Find the birth rate in births per minute. Assuming a population of 367 ​million, what was the annual birth rate in units of births per 1000​ people?

Let's solve this problem step by step.

### Step 1: Calculate the birth rate in births per minute
- There are 3,805,000 births in a year.
- A year has \( 365 \times 24 \times 60 = 525,600 \) minutes.

The birth rate in births per minute can be calculated as:

\[
\text{Births per minute} = \frac{3,805,000 \text{ births}}{525,600 \text{ minutes}}
\]

\[
\text{Births per minute} \approx 7.24 \text{ births per minute}
\]

### Step 2: Calculate the annual birth rate per 1000 people
- The population is 367 million people.

The annual birth rate per 1000 people is given by:

\[
\text{Annual Birth Rate per 1000 people} = \left(\frac{3,805,000 \text{ births}}{367,000,000 \text{ people}}\right) \times 1000
\]

\[
\text{Annual Birth Rate per 1000 people} \approx 10.37 \text{ births per 1000 people}
\]

### Final Answers:
1. The birth rate was approximately **7.24 births per minute**.
2. The annual birth rate was approximately **10.37 births per 1000 people**.

Would you like more details or have any questions?

Here are five related questions to expand your understanding:

1. How would the birth rate change if the population were to increase or decrease?
2. What factors could affect the accuracy of these birth rate calculations?
3. How would the birth rate per minute change if there were fewer births in a year?
4. How does this birth rate compare to other countries with similar populations?
5. What impact might this birth rate have on future population growth?

**Tip:** When calculating rates, always ensure that the units are consistent across the variables involved to avoid errors in interpretation.
