Introduction: Unveiling Pet Ownership Trends

Hey guys! Let's dive into an interesting statistical puzzle from South America. We're exploring pet ownership trends in a South American country where it's estimated that 4 out of every 10 households own a pet. Isn't that fascinating? Now, imagine we've surveyed a sample of 1600 households. The big question is: Based on this sample, how many households do we estimate have a furry, feathery, or scaly friend? This is where math and statistics come to our rescue, helping us unravel the numbers and get a clear picture of pet ownership in this region. So, buckle up as we crunch the numbers and reveal the estimated number of pet-owning households! We'll break down the problem step by step, making it super easy to understand how we arrive at the solution. Whether you're a math whiz or just curious about pet ownership trends, this is going to be an engaging journey into the world of statistics. Let's get started and see what the data tells us!

Understanding the Problem: Ratios and Proportions

Okay, let's break down the core of the problem. We know that in this South American country, the ratio of pet-owning households is 4 out of 10. This is a crucial piece of information. It means that for every ten households, four are likely to have a pet. This ratio gives us a proportion that we can use to estimate pet ownership in a larger sample. Think of it like a mini-snapshot of the overall population. If we can understand this mini-snapshot, we can project it onto a larger scale. Now, we have a sample of 1600 households. This is our larger scale. We need to figure out how to apply the 4 out of 10 ratio to this larger group. This is where the concept of proportion comes into play. A proportion is simply a statement that two ratios are equal. In our case, we're saying that the ratio of pet-owning households in the sample of 1600 should be the same as the ratio in the overall population (4 out of 10). So, our task is to find the number that, when divided by 1600, gives us the same proportion as 4 divided by 10. Sounds a bit like a puzzle, right? But don't worry, we're going to solve it together step by step. Understanding this fundamental concept of ratios and proportions is key to unlocking the answer. It's like having the right key to open a door – once we have it, the rest is smooth sailing. So, let's move on to the next step and see how we can apply this knowledge to our specific problem.

Calculation: Applying the Proportion to the Sample

Alright, guys, now comes the exciting part – the actual calculation! We've established that the ratio of pet-owning households is 4 out of 10, and we have a sample of 1600 households. To find out how many households in the sample are likely to have pets, we need to apply this ratio. Here's how we do it: First, we can express the ratio 4 out of 10 as a fraction: 4/10. This fraction represents the proportion of pet-owning households. Next, we simplify this fraction. Both 4 and 10 are divisible by 2, so we can reduce the fraction to 2/5. This simplified fraction is easier to work with. Now, we multiply this fraction (2/5) by the total number of households in our sample, which is 1600. This multiplication will give us the estimated number of pet-owning households in the sample. So, the calculation looks like this: (2/5) * 1600. To solve this, we can first divide 1600 by 5, which gives us 320. Then, we multiply 320 by 2, which gives us our final answer. Let's do the math: 320 * 2 = 640. So, based on our calculation, we estimate that 640 households in the sample of 1600 have pets. See? It's not as daunting as it might have seemed initially. By breaking down the problem into smaller, manageable steps, we've arrived at a clear and concise answer. Now, let's move on to the next section to confirm our result and see how it aligns with the options provided.

Solution: Identifying the Correct Answer

Okay, we've done the math, and we've arrived at an estimate of 640 households in the sample having pets. Now, let's take a look at the options provided in the question and see if our answer matches any of them. The options are: a. 4 000 b. 6 400 c. 960 d. 640 Looking at these options, it's clear that our calculated answer, 640, matches option d. That's great news! It confirms that we've approached the problem correctly and our calculations are accurate. But it's always a good idea to double-check our work, just to be sure. We can quickly recap our steps: We identified the ratio of pet-owning households as 4 out of 10, simplified it to 2/5, and then multiplied this fraction by the total number of households in the sample (1600). This gave us 640, which perfectly aligns with option d. So, we can confidently say that the correct answer is 640 households. This process of verifying our answer against the provided options is a crucial step in problem-solving. It helps us catch any potential errors and ensures that we're selecting the most accurate solution. Now that we've nailed the answer, let's move on to the final section where we'll summarize our findings and discuss the broader implications of this statistical analysis.

Conclusion: Summarizing Findings and Implications

Alright, guys, we've reached the end of our statistical journey into pet ownership in South America! Let's take a moment to recap what we've discovered. We started with the information that in a certain South American country, an estimated 4 out of 10 households own a pet. We then looked at a sample of 1600 households and used this ratio to estimate how many households in the sample would likely have pets. Through our calculations, we found that approximately 640 households in the sample are expected to have a furry, feathery, or scaly companion. This result highlights the significant prevalence of pet ownership in this region. It's fascinating to see how a simple ratio can be applied to a larger sample to make meaningful estimations. This kind of statistical analysis is incredibly valuable in many fields, from market research to public health. By understanding the proportion of pet owners in a population, for example, businesses can tailor their products and services to meet the needs of pet owners. Similarly, animal welfare organizations can use this data to plan their outreach and support efforts. But beyond the practical applications, this exercise also underscores the power of mathematics in understanding the world around us. By using basic mathematical principles like ratios and proportions, we can gain insights into complex social and demographic trends. So, the next time you encounter a statistical question, remember the steps we've taken today: understand the problem, break it down into smaller parts, perform the calculations, and verify your answer. With these tools in your toolkit, you'll be well-equipped to tackle any statistical challenge that comes your way! And that's a wrap, folks! We've successfully decoded pet ownership in South America, one calculation at a time.
