In Japan, there were 94,848 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) US population = 308 million

228228

To calculate the expected number of deaths due to heart disease in the United States, proportionally to that of Japan, we can use the following formula:

Expected deaths in the US = (Deaths in Japan / Population of Japan) * Population of the US

First, let's calculate the expected deaths in the US:

Expected deaths in the US = (94,848 / 128,000,000) * 308,000,000

Now we can perform the calculation:

Expected deaths in the US = (0.000741 * 308,000,000)

Expected deaths in the US = 228,228

Therefore, if the United States were able to reduce its number of deaths to be proportional to that of Japan, about 228,228 deaths due to heart disease would be expected. Rounded to the nearest whole number, this would be approximately 228,000 deaths.

To find the expected number of deaths in the United States due to heart disease, we can use a proportion comparing the population sizes of Japan and the United States.

First, let's calculate the proportion of the populations:

Proportion = Population of Japan / Population of the United States
Proportion = 128 million / 308 million

Next, we can use this proportion to determine the expected number of deaths in the United States:

Expected deaths in the United States = Proportion * Deaths in Japan
Expected deaths in the United States = (128 million / 308 million) * 94,848

Now, let's calculate the expected number of deaths in the United States:

Expected deaths in the United States = (0.4156) * 94,848
Expected deaths in the United States ≈ 39,399

Therefore, if the United States were able to reduce its number of deaths due to heart disease to be proportional to that of Japan, we would expect approximately 39,399 deaths.

Cross multiply and solve for x.

94,848/128,000,000 = x/308,000,000
