we know that

Expanded form is a way to write a number by adding the value of its digits

$39,012$ in expanded form is equal to

$39,012=3*10,000+9*1,000+0*100+1*10+2*1\\ 39,012=30,000+9,000+10+2$

therefore

the answer is

$39,012=30,000+9,000+10+2$

g A fair coin is tossed 20 times. The number of heads observed is the count X of successes. Give the distribution of X . Choose

Nuetrik [128]

Answer:

We assume that we have a fair coin that is $p(Head)=p(Tails)=0.5$

For this case we define the random variable X as "number of heads observed in 20 times". The distribution for X is given by:

$X \sim Binom(n=20, p=0.5)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Solution to the problem

We assume that we have a fair coin that is $p(Head)=p(Tails)=0.5$

For this case we define the random variable X as "number of heads observed in 20 times". The distribution for X is given by:

$X \sim Binom(n=20, p=0.5)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Factor the GCF: 9x4y − 6x3y2 + 3x2y3.

Ganezh [65]

For this case we have the following expression:
$9x^4y - 6x^3y^2 + 3x^2y^3
$
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:
$3x^2y
$
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:
$3x^2y (3x^2 - 2xy + y^2)
$
Answer:
the GCF is:
$3x^2y (3x^2 - 2xy + y^2)$
option A: a 3 is missing at the beginning of the option.
