cation Question 20, 3.1.40 Assuming that no questions are left unanswered, in how many ways can a ten-question true-false quiz be answered? The quiz can be answered in \( \square \) ways.

When answering a true-false quiz, each question has 2 possible answers: true or false. For a ten-question quiz, the total number of ways to answer the quiz can be calculated using the principle of multiplication. This means you take the number of choices (2) for each question and raise it to the power of the total number of questions (10). Thus, you would have: \[ 2^{10} = 1024 \] So, the quiz can be answered in 1024 ways!
