Typo in exam question no 9 and question no 17. And need explanation of question number 24.
Question No 9: Shouldn't the vector a have been a row vector to have the question being correct? I will delete comment after clarification so that the question and answer of exam won't be available here.
Question No 17: Shouldn't the first vector have been a row vector to have the question being correct? I will delete comment after clarification so that the question and answer of exam won't be available here.
Question Number 24: Need explation of why I am incorrect and explanation should be updated for everybody as this question doesn't contain explanation.

Hi, in your version of the test the correct answer for question 9 was wrong, the good one is the c. For question 17 as they are vector it doesnt matter from my point of view, it is explained like that in the course as well. And finally for question 24 the resulting of the dot product of the 2 matrix 1x3 and 3x1 is a 1x1 so you can't add a 1x3 to it so adding the sum of time penalties (twice 10s) to the result is the only way.
Hope it will help!
