According to the CDC there were 597,689 deaths in the US in 2010 attributed to heart disease.
In Japan, there were 94,974 deaths attributed to heart disease and the population of Japan is about 128 million. If the United States were able to reduce its number of deaths to be proportional to that of Japan, about how many deaths due to heart disease would be expected? (round the nearest whole number)
If the population of the US was x million, then
597689 * x/128 * 94974/128000000
To find out how many deaths due to heart disease would be expected in the United States if it had the same proportional rate as Japan, you need to calculate the death rate in Japan and then apply it to the population of the United States. Here's how you can do that:
1. Calculate the death rate in Japan:
- Divide the number of deaths due to heart disease in Japan (94,974) by the population of Japan (128 million):
Japan's death rate = 94,974 / 128,000,000
2. Calculate the expected number of deaths in the United States:
- Multiply the death rate in Japan by the population of the United States. The population of the United States is about 329 million:
Expected deaths in the United States = Japan's death rate * population of the United States
3. Round the result to the nearest whole number to get the final answer.
Now let's calculate it step by step:
1. Calculate the death rate in Japan:
- Japan's death rate = 94,974 / 128,000,000 = 0.000742
2. Calculate the expected number of deaths in the United States:
- Expected deaths in the United States = 0.000742 * 329,000,000 = 244,018
3. Round the result to the nearest whole number:
- The expected number of deaths due to heart disease in the United States would be approximately 244,018.
So, if the United States had the same proportional rate as Japan, about 244,018 deaths due to heart disease would be expected.
