Question

Please help with this I have no idea what to do and how to find the answer!!!!!

Answer 1

82.49 percent were at least high school graduates.

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:
`y-y_1=(y_2-y_1)/(x_2-x_1)\cdot (x-x_1)`

Substituting the values in the formula we get:

`y-34.7=(87.8-34.7)/(50-0)(x-0)`

`y-34.7=1.062(x)`

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.
