Answer:
23.607
Step-by-step explanation:
<em> Given:</em>
$65,575
9%
4 Year
4 x 9% = 0.36
65,575 x 0.36 = 23.607

The life expectancies of residents of a country for which the average annual income is $80,000 for the three models are 12309.9352, 172.2436 and 4828.1393
The life expectancies of the models are given as:
--- model 1
--- model 2
--- model 3
Given that the average annual income is $80,000;
We simply substitute 80000 for income in the equations of the three models.
So, we have:
<u>Model 1</u>
![y =69.9352 + 0.1530\times (income)](https://tex.z-dn.net/?f=y%20%3D69.9352%20%2B%200.1530%5Ctimes%20%28income%29)
![y =69.9352 + 0.1530\times 80000](https://tex.z-dn.net/?f=y%20%3D69.9352%20%2B%200.1530%5Ctimes%2080000)
![y =12309.9352](https://tex.z-dn.net/?f=y%20%3D12309.9352)
<u>Model 2</u>
![y =4.2436 + 0.0021\times (income)](https://tex.z-dn.net/?f=y%20%3D4.2436%20%2B%200.0021%5Ctimes%20%28income%29)
![y =4.2436 + 0.0021\times 80000](https://tex.z-dn.net/?f=y%20%3D4.2436%20%2B%200.0021%5Ctimes%2080000)
![y =172.2436](https://tex.z-dn.net/?f=y%20%3D172.2436)
<u>Model 3</u>
![y =4.1393 + 0.0603\times (income)](https://tex.z-dn.net/?f=y%20%3D4.1393%20%2B%200.0603%5Ctimes%20%28income%29)
![y =4.1393 + 0.0603\times 80000](https://tex.z-dn.net/?f=y%20%3D4.1393%20%2B%200.0603%5Ctimes%2080000)
![y =4828.1393](https://tex.z-dn.net/?f=y%20%3D4828.1393)
Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393
