Final answer:
The numerical value of coefficient a is 0.6667 (or 2/3 in fraction form), and the numerical value of coefficient b is 0.075 (calculated by dividing the product of 2 and 3 by 80).
Step-by-step explanation:
To determine the numerical values of the coefficients a and b as given in the student's question, we can simply evaluate the expressions provided. For coefficient a, the expression is a straightforward fraction, a = 2/3. Evaluating this expression gives us the numerical value of a which is approximately 0.6667.
For coefficient b, the expression is b = 2*3/80. This requires two operations: multiplication and division. First, we multiply 2 by 3, resulting in 6. Next, we divide this product by 80, giving us the numerical value of b which equals 0.075.
