To score 65% you would need to answer 32.5 questions correctly. As you can't answer half a question correctly, you will need to answer 33 correctly resulting in a mark of 66%. Thus you can miss 17.
You can miss 31.5 questions. 105*70%(.70)=73.5 105-73.5= 31.5
To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.
64, of course. Unless you mean how many can you miss and still pass... 70% of 64 is 44.8, so you need 45 to pass so you can miss 19.
To get a 70 to pass the test you can miss 37 questions.
To achieve a score of 70% on a test of 125 questions, you would need to answer 87.5 questions correctly (125 questions x 70% = 87.5 questions). Since you can't answer half of a question, you would need to round up to 88 questions. Therefore, you can miss 37 questions (125 total questions - 88 questions answered correctly = 37 questions missed) and still achieve a score of 70%.
To pass with 80 percent on a test of 110 questions, you need to answer at least 88 questions correctly (80% of 110 is 88). This means you can miss a maximum of 22 questions (110 - 88 = 22). Therefore, you can miss 22 questions and still pass with 80 percent.
You can miss 31.5 questions. 105*70%(.70)=73.5 105-73.5= 31.5
To achieve an 80 percent score on a 27-question test, you would need to answer 80% of the questions correctly. This means you can get 20% of the questions wrong. To calculate the number of questions you can miss, multiply 27 by 0.20 (20%) to get 5.4. Since you can't have a fraction of a question, you would need to round down to 5 questions. Therefore, you can miss 5 questions out of 27 to achieve an 80 percent score.
To get seventy percent or better on a quiz of 16 questions one needs 11.2 answers correctly answered. So it is best not to miss 4 but definitely not to miss 5 or more. This answer is arrived at by taking the 16 questions and multiplying by .70 (70 percent) or 16 x .70 = 11.2.
You would need to answer 52 questions correctly out of 73 to pass with a 71%. That means you could miss a total of 21 questions.
To achieve 75 percent on a test with 125 questions, you need to answer at least 94 questions correctly (since 75% of 125 is 93.75, which rounds up to 94). Therefore, you can miss out on a maximum of 31 questions (125 - 94 = 31) to still reach that passing score.
To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.
64, of course. Unless you mean how many can you miss and still pass... 70% of 64 is 44.8, so you need 45 to pass so you can miss 19.
To get a 70 to pass the test you can miss 37 questions.
To achieve a score of 70% on a test of 125 questions, you would need to answer 87.5 questions correctly (125 questions x 70% = 87.5 questions). Since you can't answer half of a question, you would need to round up to 88 questions. Therefore, you can miss 37 questions (125 total questions - 88 questions answered correctly = 37 questions missed) and still achieve a score of 70%.
Assuming that all questions score equally, you can miss out at most 7. And then need to get them all correct.
