The marks of 16 students in math in monthly test are 0, 0, 2, 2, 3, 3, 3, 4, 5, 5, 5, 5,6, 6, 7, 8, then mode will be
5
6
3
7
If , then the values of x are
1,-2
-1,-2
0,1
2,-1
D.
2,-1
put 3x=y....(1)
If
Then
also,
then, y=9
From Equation 1,
therefore x=-1
also 3x = 9
3x = 32
therefore x=2
If distance between centre to chord is 12 cm and length of chord is 10 cm, then the diameter of circle is
