Answer:

The lowest ccommon denominator (or LCD) of 1/3 and 2/5 is 15.

Step-by-step explanation:

The lowest multiple of 3 and 5 is 3*5 = 15.

In terms with the LCD, 1/3 now equals 5/15; and 2/5 now equals 6/15.

Hope this helps :)

Find the domain and range of y=-5x-1

harina [27]

Answer:

$\mathrm{Domain\:of\:}\:-5x-1\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

$\mathrm{Range\:of\:}-5x-1:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Step-by-step explanation:

Finding the domain:

The domain of a function is the set of possible input values for which the function is real and defined.

Given the function

$y=-5x-1$

The function has no undefined points nor domain constraints. Hence, the domain is

$-\infty \:$

i.e.

$\mathrm{Domain\:of\:}\:-5x-1\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Finding the range:

The range of a function is the set of possible output values (dependent variable y values) for which a function is defined.

The range of polynomials with odd degree is all the real numbers.

Hence, the domain is

$-\infty \:$

i.e.

$\mathrm{Range\:of\:}-5x-1:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

A fair coin is tossed 5000 times. What can you say about getting the outcome of exactly 2500 tails

WINSTONCH [101]

Step-by-step explanation:

You can't expect to get exactly 2500 out of 5000 tosses more than a few times . You will come pretty close, but that's only good in horseshoes.

Of course I'm answering this on the basis of a computer language and not actually performinig this a million tmes, each part of a million consisting of 5000 tosses.

Simulations and not completely unbiased, but based on experience, 5000 is a very small number and getting 2500 more than a couple of times is unlikely
