hi there this is an easy question and the question is simply for finding the centroid of a triangle to begin with consider the third unknown vertice to be (x,y) so avg of all x cordinates of the triangle vertices should be equal to 3 as it is given 3 is the x cordinate of the center therefore (0+6+x...

hi there in case of finding 10's present in any factorial we have to ind out how many 5's were present in the product of those integers present in the factorial since 2 will be abundantly present in the product it is not worth finding it now the question is why do we find 2's and 5's since only thes...

in all there are 45 number of rocks including all type of them
15 slate+20 pumice+10 granite=45 rocks

2 rocks can be selected in 45C2 ways=22*45

on other hand to select 2 slate rocks can be selected in 15c2 ways = 7*15

hence probability of slate rock picking=(7*15)/(22*45)=7/66

First of all let us find the lowest price of the car sold in the two months period ie may and june since the least price of car sold in may is 4500 less than the least cost of the car sold in june which was 6100 so we have the lowest value in order to find the range=4500 consider the month of may ra...

As per data table is given below No of students in 1)kinder = 96 2)1st G + 2nd G=120 3)3rd G+4th G= 2x. 4)5th G+ 6th G= 128. so ad...

It seems you have jotted the question wrongly which area is asked for is it ABD or ABC is C or D one of the vertices for the triangle please do let know seems to be a simple question
