The United States has a population of about 320 million. If our homicide deaths were proportional to that of Honduras, how many deaths would we expect in the

Answer 1

a)Express the death per capita as a decimal rounded to 6 decimal places

0.000875 death per capita

b) Express the death per capita in Scientific notation

8.75 × 10^-4 death per capita

c) 279883 deaths

Explanation:

a) Express the death per capita as a decimal rounded to 6 decimal places

The formula for Death Per capita is given as

Number of deaths/ Total population

Measurement : 7172 homicide deaths

Total population : 8.2 millon= 8,200,000

Death per capita = 7172/8200000

Death per capita = 0.00087463414 death per capita.

Approximately to 6 decimal places

= 0.000875 death per capita.

b) Express the death per capita in Scientific notation

The death per capita = 0.000875

In Scientific notation = 8.75 × 10^-4 death per capita

c) The United States has a population of about 320 million. If our homicide deaths were proportional to that of Honduras, how many deaths would we expect in the United States due to homicides? Round to the nearest person.

Measurement : 7172 homicide deaths

Total population : 8.2 millon= 8,200,000

The United States has a population of about 320 million

Death per capita in Honduras : Death per capita in United States

7172/8200000 : x/320,000,000

7172/8,200,000 = x/320,000,000

Cross Multiply

7172 × 320,000,000 = 8,200,000 × x

x = 7172 × 320,000,000/8,200,000

x = 279882.926829 deaths

Approximately to the nearest person = 279883 deaths
