" (i) "12:18=8:12

Verify that: 12:18 = 8:12

The 13 th term in the expansion of (9x-1/(3sqrt(x)))^(18),x gt0 is (i) ""^(18)C_(12)x^(3) (ii) ""^(18)C_(12)x^(6) (iii) ""^(18)C_(12)1/(x^(6)) (iv) ""^(18)C_(12)

Which number in each of the following pairs is larger? (i) 3,\ -4 (ii) -12,\ -8 (iii) 0, 7 (iv) 12 ,\ -18

Which number in each of the following pairs is larger? (i) 3, -4 (ii) -12, -8 (iii) 0, 7 (iv) 12 , -18

If x : 12 : : 12 : 18. then x is

The marks obtained by 40 students of class VIII in an examination are given below: 16,17,18,3,7,23,18,13,10,21,7,1,13,21,13,15,19,24,16,3, 23,5,12,18,8,12,6,8,16,5,3,5,0,7,9,12,20,10,2,23 Divide the data into five groups, namely 0-5, 5-10, 10-15, 15-20 and 20-25 and prepare a grouped frequency table.

Fill the appropriate number in the box. (8 ^(8))/( 8 ^(3)) = 8 ^( 8-3) = 8 ^(5) (12 ^(12))/( 12 ^(7)) = 12 ^( square) = 12 ^( square)

Verify the following : (-8)+(-12)=(-12)+(-8)
