The odds against selecting a red marble is =2/11

<h3>Calculation of probability</h3>

The number of marbles which were red = 9

The number of marbles which were blue = 2

The total amount of marbles in the Box = 11

When one marble is picked at random from the box, the odds against selecting a red marble can be gotten through the blue marble.

That is, the number of blue marble/ total marble

= 2/11

What is the surface area of the rectangular prism?

algol [13]

let me lie down this prism.

Check the picture below.

so the prism is really 6 rectangles stacked up to each other at the edges, so we can simply get the area of each rectangle and sum them up.

$\bf \stackrel{rectangles}{\stackrel{\textit{top and bottom}}{2(3.5\cdot 9)}~~~~+~~~~\stackrel{\textit{left and right}}{2(9\cdot 5)}~~~~+~~~~\stackrel{\textit{front and back}}{2(3.5\cdot 5)}} \\\\\\ 63+90+35\implies 188$

Find f. f ''(x) = −2 + 24x − 12x2, f(0) = 7, f '(0) = 16

miskamm [114]

Integrate twice.

Remember the anti-derivative rule for polynomials:
$\int x^n dx = \frac{x^{n+1}}{n+1} + C$

$f'(x) = \int (-2 +24x -12x^2) dx = -2x + 12x^2 -4x^3 + C \\ \\ f'(0) = 16, C = 16 \\ \\ f(x) = \int (16 -2x+12x^2-4x^3) dx = 16x -x^2 + 4x^3 - x^4 + C \\ \\ f(0) = 7, C = 7$

Answer:
$f(x) = 7 + 16x -x^2 + 4x^3 - x^4$
