My initial think was 0.25% as well

How reliable are the answers of the question's source?

 

[davidgoes4wce]

There are no answers, just ticks and crosses.

No solutions given to student.

No solutions given to student.

But you said the answer was D) – is this reliable?

 

[davidgoes4wce]

No its not reliable. if you read the first post on Page 3 of this forum, they got the radial survey question wrong as well. I'll post up the exam page online now.

 

[davidgoes4wce]

The teacher who marked it on the MCQ gave Q14 D (was deemed wrong), Q15 D (was deemed correct)


Im skeptical because when I did Q 14 :







Which was marked wrong.

 

[InteGrand]

In that case, yeah, answer should surely be +/- 0.25%.

 

[davidgoes4wce]

I also won't name the school paper this is from, for privacy reasons.

Yeah it appears that these markings are quite unreliable.

This school has fckued up their students , they have done Question 16 wrong as well.

Wouldn't the students have complained if there were so many blatant errors?

Question 16:

 

[davidgoes4wce]

Wouldn't the students have complained if there were so many blatant errors?

The student that I am tutoring wasn't good enough , he failed the General Maths exam. I don't think he would have been able to spot the errors out and he left half of the short answer section.

Question 16:

Which answer was marked correct here?

 

[davidgoes4wce]

Theory behind that question

 

[davidgoes4wce]

My answer would have been B, the answer that was marked correct was D

 

[InteGrand]

My answer would have been B, the answer that was marked correct was D

Yeah it should be B) (Simpson's Rule).

 

[InteGrand]

Is the reason the teachers marked that wrong that they didn't understand the theory themselves?

If you have access to other years' papers from that school, you could maybe check how correctly those ones were marked, to see if this is a recurring problem.

 

[davidgoes4wce]

I won't show the name of the student or the school for privacy reasons but this is how they mark the MCQ's:

Just wondering if there has been a mistake made in the Year 11 Oxford General Maths textbook for Chapter 2 Q 11.

Saw an example of this nature from the text book:










My initial thinking with this question was to find the Limit of Reading value which in this case, I thought it was 1 gram. (As I speak I've realised they have used the Limit of Reading value of 10 grams as stated in the question)





After having a deeper thought about it, I think the answer is (but I really don't like the logic behind it):
