The denominator. Say for instance, you have 4/12 and 1/6. They are equivalent.

Simplify all fractions. If they reduce to be the same fraction, then the fractions are equivalent.

Cross multiply. If the two products are equal, then the fractions are equivalent.

Get a common denominator and compare numerators.

What is the probability of rolling a number less than five on a standard number cube (6 sides)

fgiga [73]

<h3>Answer: 2/3</h3>

Here are the outcomes that are less than five = {1, 2, 3, 4}. There are A = 4 values here.

Here are all the outcomes possible: {1, 2, 3, 4, 5, 6}. There are B = 6 ways to roll a single number cube (aka dice).

Divide the two values: A/B = 4/6 = (2*2)/(2*3) = 2/3

The fraction 2/3 is approximately equal to 0.667 which converts to 66.7%

Find the laplace transform of f(t)={0,(t−4),0≤t<4t≥4

Masja [62]

Presumably,

$f(t)=\begin{cases}0&\text{for }0\le t$

By definition of the Laplace transform,

$\mathscr L_s\{f(t)\}=\displaystyle\int_0^\infty f(t)e^{-st}\,\mathrm dt=\int_4^\infty(t-4)e^{-st}\,\mathrm dt$

Integrate by parts, taking

$u=t-4\implies\mathrm du=\mathrm dt$
$\mathrm dv=e^{-st}\,\mathrm dt\implies v=-\dfrac1se^{-st}$

so we get

$\displaystyle\mathscr L_s\{f(t)\}=\left(-\frac1se^{-st}(t-4)\right)\bigg|_{t=4}^{t\to\infty}+\frac1s\int_4^\infty e^{-st}\,\mathrm dt$
$=-\dfrac1{s^2}e^{-st}\bigg|_{t=4}^{t\to\infty}$
$=\dfrac{e^{-4s}}{s^2}$
