248,682 rounded to nearest hundred means just look at the hundreds place which is the 6. Now the number to the right of that is the 8 and that is the number that helps you decide to round up or down. If it is 4 or lower, keep the hundreds place the same. If it is 5 or higher then round up 1. Then any number that follows the hundreds place all change to 0.

The population of the country was 314 million. What is the empirical probability of death by stroke during a single year

Marat540 [252]

Answer:

Empirical probability of deaths cause by stroke=0.004086

Empirical probability of deaths cause by kidney disease =0.001436

Death rate due to stroke is 4 times the death rate due to kidney disease.

Step-by-step explanation:

Consider the table attached in figure

No. of deaths cause by stroke = 128300

No. of deaths caused due t kidney disease = 45100

Total population = 314 x 10⁵

Formula to calculate empirical probability:

$P(A)=\frac{No.\, of\,\, times\,\, event\,\, occurs}{Total\,\, population}\\$

Empirical probability of deaths cause by stroke:

$P(A)=\frac{128300}{314\times 10^5}\\\\P(A)=0.004086$

Percentage of deaths cause by stroke =0.4%

Empirical probability of deaths cause by kidney disease:

$P(B)=\frac{45100}{314\times 10^5}\\\\P(B)=0.001436$

Percentage of deaths cause by kidney disease =0.1%

Ratio between deaths caused to stoke to deaths caused by kidney disease is 4:1 which means death rate due to stroke is 4 times the death rate due to kidney disease.
