Minchanka [31]

Answer:

12/15 and 16/20

Step-by-step explanation:

<h3>What is a polynomial?</h3>

a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

P(x)=0.7166x²+6.267x+1.344

when x = 0, it represents 1997

Substitute the value of x as zero in polynomial.

P(0)=0.7166(0)²+6.267(0)+1.344

P(0)=0+0+1.344

P(0)=1.344

The amount of coffee imported in the year 1997 was approximately 1.344 pounds.

Hence amount of coffee imported in the year 1997 was approximately 1.344 pounds.
