We need to evaluate the expression (11-3²)/10. Let's work through this step by step. First, we evaluate the exponent 3² which equals 9. Then we substitute this back into our expression.
The first step is to evaluate the exponent. We calculate 3 squared, which means 3 times 3, equals 9. Now we can substitute this value back into our original expression, replacing 3² with 9.
Next, we perform the subtraction in the numerator. We calculate 11 minus 9, which equals 2. This gives us the fraction 2 over 10.
Finally, we simplify the fraction 2 over 10. We can divide both the numerator and denominator by their greatest common divisor, which is 2. This gives us 1 over 5. Therefore, the answer is one-fifth, which corresponds to option D.
Let's verify our answer by checking the multiple choice options. We calculated that the expression equals one-fifth. Looking at the options: A is 2, B is 6.4, C is one-half, and D is one-fifth. Our answer matches option D, so the correct answer is D.
