So basically there was a test with 72 questions and you got x number of them wrong, and got 70%.
So... You have to find out what 70% of 72 is.
All you have to do is multiply 0.70 by 72. Which equals 50.4
50 represents the number of questions you got right out of 72.
So, 50/72 = roughly 70%
--------------------------------------------------------------------------------------------------
72 - 50 = 22
SO. To answer you question, you can miss 22 questions out of 72 to get 70 percent.
Why does it sound like you're trying to go all lazy on a test?
18
70% of 15 is 10.5 so it is 4.5 questions
No more than 19. You can do it!
Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
14 miss 35 correct 35/49 = 0.714 = 71.4%
18
To achieve a score of 70 percent on a 25-question test, you need to answer at least 18 questions correctly (70% of 25 is 17.5, which rounds up to 18). This means you can miss a maximum of 7 questions (25 - 18 = 7). Therefore, you can miss 7 questions to still score 70 percent or above.
70% of 15 is 10.5 so it is 4.5 questions
No more than 19. You can do it!
Not more than 11.
14 miss 35 correct 35/49 = 0.714 = 71.4%
Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
70% of 12 is 8.4 and 12 minus 8.4 = 3.6
To score 70 percent on a 30-question driving test, you need to answer at least 21 questions correctly (70% of 30 is 21). Therefore, you can miss up to 9 questions (30 total questions minus 21 correct answers) to still achieve a passing score of 70 percent.
To achieve a score of 70 percent on a 10-question test, you need to answer at least 7 questions correctly. This means you can miss a maximum of 3 questions. Therefore, missing 3 questions would still allow you to meet the 70 percent threshold.
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.
2 * (50 - x) = 70 50 - x = 35 x = 15 You can miss 15 questions.
