- ஒரு மதிப்பெண் வினாவில் 15வது கேள்வியில் தமிழில் "ஒரு நாணயத்தை மூன்று முறை சுண்டும் சோதனையில் 3 தலைகள் அல்லது 3 பூக்கள் கிடைக்க நிகழ்தகவு" என்று உள்ளது. ஆங்கிலத்தில் "Probability of getting 3 heads and 3 tails in tossing a coin 3 times is:"என்று உள்ளது.
- 5 மதிப்பெண் வினா பகுதியில் வினா எண் 38ல் தமிழில் "(0,5), (-2,-2), (5,0), (7,7) என்ற புள்ளிகளை உச்சிகளாக கொண்ட நாற்கரமானது ஒரு சாய்சதுரம் என நிரூபி" என்று உள்ளது. ஆங்கிலத்தில் "Prove that (0,5), (-2,-2), (5,0) and (7,7) are the vertices of a rhombus." என்று உள்ளது.

ReplyDeleteSec-3 34th question is wrong (four consecutive terms) three consecutive terms
ReplyDeletethis question is creative.it is correct
Deleteno.this question is correct.it is a framed question.the terms must be taken as a-3d,a-d,a+d,a+3d.the answer is 2,4,6,8 or 8,6,4,2.
DeleteThe 15th question is book back and has answer
ReplyDelete1) English version of Q.No.15 is wrong
ReplyDelete2) Q.No.34 and 38 are out of book
q.no 15 eng med book back answer correct give full mark tamil med any option q.no 15
ReplyDeleteIn graph second question we can take simple interest in X axis and deposit money in Y axis we get K=10 and correct answer Please reply ur suggestions
ReplyDeleteY=KX,
DeleteSo,K=10 also correct
Thank you some of the students did this graph in this way can they get full mark?
Deleteqn no 34 2nd chapter remark and use it four consecutive terms
ReplyDeleteTake a+3d,a+d,a-d,a-3d are the four consecutive nos u can get the answer
DeleteFor rhombus the diagonals are perpendicular. Use slope formula we get the answer
DeleteIf we use midpoint formula also,it gives the answer for Rhombus sum(Q.NO:38).Midpoint of AC = Midpoint of BD.
DeleteQ.NO:38.Rhombus sum can be done by using midpoint formula.Midpoint of AC = Midpont of BD. IS THIS CORRECT?PLEASE REPLY ME!!!
ReplyDeleteIn parallogram the diagonals bisect each other but in rhombus they don't bisect each other&perpendicular each other so think slope formula is right what's your opinion about graph question?please reply ur suggestions
ReplyDeleteRhombus is a parallelogram all of whose sides are equal. So,its diagonals are perpendicular bisectors to one another. We have to prove that their midpoints are same and also they are perpendicular.
ReplyDeleteAnother way to prove that it is a rhombus, it should be proved that the slopes of opposite sides are equal and also that any two adjacent sides are equal.
Thank you sir please tell yr opinion on graph question-second one shall we interest in X axis and deposit money in Y axis?
ReplyDeleteThank you sir please tell yr opinion on graph question -second one shall we take interest in X axis and deposit money in Y axis?
ReplyDeleteIn question no. 38 it is not given whether the given points are vertices of a quadrilateral. Without that knowledge it is wrong to proceed. Pl clarify sir.
ReplyDeletePlot the points on a graph.Then you will find that all the four points form a quadrilateral. Any method can be used to prove that it is a rhombus.
ReplyDeletePlease can anybody clarify the graph sum?
