Establish for which constants c the following function is a density.

Valentin [98]

By "density" I assume you mean "probability density function". For this to be the case for $f(x)$ , we require

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=1$

Since

$f(x)=\begin{cases}cx^{1/2}&\text{for }0$

you have

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2cx^{1/2}\,\mathrm dx=\dfrac{2c}3x^{3/2}\bigg|_{x=0}^{x=2}=\dfrac{2^{5/2}c}3=1$

which means

$c=\dfrac3{2^{5/2}}=\dfrac3{4\sqrt2}$

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr

Alex Ar [27]

Answer:

3/68

Step-by-step explanation:

<u>Given</u>

Total 17 marbles
4 - blue marbles
6 - green marbles
2 - red marbles
The rest - yellow marbles

<u>Probability of drawing red first:</u>

P(red) = number of red / total number = 2/17

<u>Probability of drawing green second, without replacement:</u>

P(green) = number of green / number left in the bag = 6/16 = 3/8

<u>Probability of red and green in order:</u>

P = P(red)*P(green) = 2/17*3/8 = 3/68

Least common multiple of 30 25 4

White raven [17]

Answer:

The least common multiple of 30, 25, 4 is 150.

Step-by-step explanation:

The given numbers are 30, 25 and 4.

The factors of given numbers are

$30=2\times 3\times 5$

$30=5\times 5$

$4=2\times 2$

The L.C.M of given numbers is a smallest number that divides the given numbers completely.

$L.C.M.=\frac{2\times 3\times 5\times 5\times 5\times 2\times 2}{5\times 2}$

$L.C.M.=2\times 3\times 5\times 5\times 2=150$

Therefore the least common multiple of 30, 25, 4 is 150.
