Question

The table shows a company’s profit based on the number of pounds of food produced.

A 2-column table with 5 rows. The first column is labeled pounds of food produced with entries 100, 250, 500, 650, 800. The second column is labeled profit (dollar sign) with entries negative 11,000; 0; 10,300; 11,500; 9,075.
Using the quadratic regression model, which is the best estimate of the profit when 350 pounds of food are produced?

$5,150
$5,300
$10,150
$11,000

Answer 1

$5,300

(Quadratic regression gives an estimate ≈ \$5,353 for 350 lb, so the closest choice is \$5,300.)
