Question

Interpolate: Use the equation to determine what the student enrollment in 2003 likely was.

Answer 1

Answer:

1244 students

Explanation:

That would be y = 82*3 + 998

= 1244.

Answer 2

Answer:

The expected student enrollment in 2003 is 1244.

Explanation:

The given diagram it is clear that the graph represents the relationship x and y, where x is number of years since 2000 and y is number of student enrollment.

From the given figure it is clear that the equation of best fit line is

$y=82x+998$       .... (1)

We need to find the expected student enrollment in 2003.

Year 2003 is 3 years since 2000.

Substitute x=3 in equation (1) to find the expected student enrollment in 2003.

$y=82(3)+998$

$y=246+998$

$y=1244$

Therefore the expected student enrollment in 2003 is 1244.
