Answer:
82.49 percent were at least high school graduates.
Step-by-step explanation:
We have been given that at 1950 x=0
and at 1960 x=10
And following this pattern at 2000 x=50
So, we have coordinates:
(0,34.7) and (50,87.8) for two point form we will find a function:
Using:[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}\cdot (x-x_1)[/tex]
Substituting the values in the formula we get:
[tex]y-34.7=\frac{87.8-34.7}{50-0}(x-0)[/tex]
[tex]y-34.7=1.062(x)[/tex]
y=1.062 x+34.7 is the linear function
(b) Now, we need to find the value at x= 1995 which will be equal to 45 according to the pattern followed
Put x=1995 in the function above we get:
y =1.062(45)+34.7
y=82.49 percent were at least high school graduates.
