hi
Bunuel I am not able to understand the question clearly
What does it mean when we say ' The mean of four integers will not change if all the integers are multiplied by
any constant. '
Does it mean that all numbers are multiplied by one same constant for instance [ 1,2,3,4,5 ] new set [ 1*2 , 2*2 ,3*2 , 4*2 , 5*2 ]
or
does it mean that all numbers are multiplied by any constant meaning different constant [ 1*1 , 2*2, 3*3 ,4*10 ,5*20 ].
Kindly help me with the same
thanks in advance
it means if your set is {1,2,3,4,5} and is multiplied by a constant say 2, then the resultant set would be {2,4,6,8,10}
This is only possible if your set is centered at 0, including all zeros
So for example if your set is {-2,-1,0,1,2}, mean of this set = 0
Multiply this set with say a constant 100, resultant set={-200,-100,0,100,200}, mean = 0
