When twice a non zero positive numbr is divided by its cube root the quotient is obtained as 32 .If the cube of the number is divided by the number itself then the quotient is ___________
A. n/a
B. n/a
C. n/a
D. n/a
Correct Answer - D
Let the probability for getting an odd number be p. Therfore the probability for getting an even number is 2p.
`thereforep+2p=1orp=1/3`
Sum of two numbers is even...
Correct Answer - C
`(c )` ` (a^(2)+b^(2))x^(2)-2b(a+c)x+b^(2)+c^(2)=0`
`D=4b^(2)(a+c)^(2)-4(a^(2)+b^(2))(b^(2)+c^(2))`
`=-4(b^(4)-2b^(2)ac+a^(2)c^(2))`
`=-(n^(2)-ac)^(2)`
For real roots, `D ge 0`
`implies -4(b^(2)-ac)^(2) ge 0`
`implies b^(2)-ac=0`
`implies` Roots are real and equal.
`:.` Roots...
