Answer:
35.29%
Explanation:
no. of questions in test = 34
no. of questions answered correctly = 22
therefore, no. of questions answered incorrectly = 34 - 22
= 12
error percentage = 12/34 * 100
= 35.29%
Answer: John's percentage error is 35.3 %.
Explanation:
To calculate the percentage error, we use the equation:
[tex]\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100[/tex]
We are given:
Number of questions answered by John = 22
Total number of questions = 34
Putting values in above equation, we get:
[tex]\%\text{ error}=\frac{|22-34|}{34}\times 100\\\\\%\text{ error}=35.3\%[/tex]
Hence, John's percentage error is 35.3 %.
