Answer:
193.586 deaths per 100,000
Step-by-step explanation:
The cause-specific mortality rate for a disease in a per 100,000 basis is determined as the total number of deaths due to the disease multiplied by 100,000 and divided by the average (mid-year) total population.
There were 597,689 deaths due to diseases of the heart in a population of 308,745,538 people. The cause-specific mortality rate for diseases of the heart per 100,000 in this population is:
[tex]M=\frac{597,689}{308,745,538}*100,000\\ M=193.586\ deaths/100,000[/tex]
The mortality rate is 193.586 deaths per 100,000.
