35%
50 is half of 100; 50 x 2 = 100 35 x 2 = 70 answer is 70%
Percentage increase from 50 to 70 is (20/50) x 100 = 40% Percentage decrease from 70 to 50 is (20/70) x 100 = 28.5714%
To do this problem, you set up a proportion: 50 percent of 100 is equal to what (x) percent of 70? It should look like this: 50/100 = x/70 To solve this problem, divide 50 by 100: .5 = x/70 To finish the equation, times both sides by 70: (.5)(70) = (70)(x/70) [The x70 and /70 cancel each other out] 35 = x So, 50% of 70 is 35.
It is not possible to answer the question without knowing how much of the total each one is worth. If they are both equally important, then the answer is 50% but they are rarely (if ever) equally important. If the test grade is worth x percent of the total - not your grade but how much weight it carries in the total - then the average is [x*70+(1-x)*30]/100
6 wrong means 14 correct. 14/20 * 100% is 70%.
To achieve a score of 70 percent on a 50-question test, a student must answer at least 35 questions correctly (70% of 50). This means they can get a maximum of 15 questions wrong (50 - 35 = 15) and still meet the passing criteria.
70 percent of 60 is 42. The points don't enter into it.
2 * (50 - x) = 70 50 - x = 35 x = 15 You can miss 15 questions.
The " 70% " score represents the fraction of the questions that you answered correctly.If you answered 70% correctly, you missed the remaining 30% .30% of 50 = 0.3 x 50 = 15 .
To obtain that answer you multiply 35 by .70. The answer is thus 24.5.
In order to score 70 or below on a 50-question test, you must answer at least 15 of them wrong.
It is 70%
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?
