What is the value of k if 2x^3-3x^2+kx-4 is divided by x-3 and gives a remainder of -7?

Alik [6]

By the polynomial remainder theorem, the remainder upon dividing a polynomial $p(x)$ by $x-c$ is the same as the value of $p(c)$ .

Here $p(x)=2x^3-3x^2+kx-4$ and $c=3$ . We have

$p(3)=23+3k=-7\implies k=-10$

Let x be the number of successes throughout n independent repetitions of a random experiment having probability of success p=1/4

Llana [10]

To answer problems like this you have to use binomial:

P (x > 1) = 1 – p (0 < x < 1) > .7

So:

1 – p (0) – p (1) > .7

1 – (3/ 4) ^n – (3/ 4) ^n (n – 1 ) (1/ 4) > .7

Therefore n > 5.185, and the smallest value of n so that we can satisfy the given condition is 6 (rounded up)
