In a northern European country.

Question

_{^{In a northern European country, the formula y = 0.032}}x²− _{^{2.5x + 62.54}}

^{_{models the number of deaths per year per thousand people, y , for people who are x years old, 40 ≤ x ≤ 60. Approximately how many people per thousand who are 60 years old die each year? For the purposes of this problem, please round your answer to a whole number.}} 

Answer 1

Since the units are consistent, we can simply evaluate y when x=60.

 

y = 0.032(60)² - 2.5(60) + 62.54

 

Simplify to get y.  Then round off to the nearest whole number as your question requests.
