Answer:
55.75
Step-by-step explanation:
find the area of 1 side using the base and height and divide that answer by 2
5x6=30 30 divided by 2=15
all sides are equal so each side is 15
the base you do the same thing.
base is 5, height is 4.3
4.3 x 5= 21.5
divide it by 2 10.75
side 1=15
side 2= 15
side 3=15
base 1= 10.75
add all together
55.75
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>



<u>Model 2</u>



<u>Model 3</u>



Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393
