Answer:

Approximately 19 people per thousand who are 44 years old die every year.

Step-by-step explanation:

To solve this problem, we have to substitute x by 44 (age).


\begin{gathered} y=0.032x^2-2.4\cdot x+62.58 \\ y=0.032\cdot44^2-2.4\cdot44+62.58 \\ y=61.95-105.6+65.58 \\ y=18.93 \\ y=19 \end{gathered}

Answer: Approximately 19 people per thousand who are 44 years old die every year.
