Answer:
10 incorrect answers
Step-by-step explanation:
Correct answer = +3
Incorrect answer = - 1
Mark scored = 20
Number of correct answers = 10
Let:
Incorrect answers = y
Hence, we can fashion out the expression for total score :
(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score
(10 * 3) + (y * - 1) = 20
30 - y = 20
-y = 20 - 30
-y = - 10
y = 10
10 incorrect answers
Answer:
6
Step-by-step explanation:
There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.
So without all the insignificant 0's, the number would look like this:
13.0049
