Please find the domain

So there are two things:
Domain and Range
Domain is the x value
and Range is the y value
THE Y VALUE IS ALWAYS DEPENDENT ON THE X VALUE
Therefore, the range is always dependent on the domain
In this line, there are arrows at the end of the line meaning that it goes on and on
If you look at it closer, the x value goes on and on without limitations
But the y value changes based on where the x value is, so it can't go anywhere it wants like the x value can

Therefore, if the x value or DOMAIN is infinite, that's the same as saying the *Domain is limited to all real numbers* since all other options restrict the x value AND because the term "all real numbers" basically means "infinite" in graphing

A student studying for a vocabulary test knows the meanings of 16 words from a list of 20 words. If the test contains 10 words f

Murrr4er [49]

Answer:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)$

And we can find the individual probabilites:

$P(X=8) = 10C8 (0.8)^8 (1-0.8)^{10-8}= 0.302$

$P(X=9) = 10C9 (0.8)^9 (1-0.8)^{10-9}= 0.268$

$P(X=10) = 10C10 (0.8)^9 (1-0.8)^{10-10}= 0.107$

And adding the values we got:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)= 0.302+0.268+0.107= 0.678$

Step-by-step explanation:

Previous concepts

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".

Solution to the problem

For this case the probability of success is given by:

$p = \frac{16}{20}= 0.8$

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=10, p=0.8)$

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:

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

And we want to find the following probability:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)$

And we can find the individual probabilites:

$P(X=8) = 10C8 (0.8)^8 (1-0.8)^{10-8}= 0.302$

$P(X=9) = 10C9 (0.8)^9 (1-0.8)^{10-9}= 0.268$

$P(X=10) = 10C10 (0.8)^9 (1-0.8)^{10-10}= 0.107$

And adding the values we got:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)= 0.302+0.268+0.107= 0.678$

2. TWENTY-FIVE AND THREE THOUSANDTHS AS A DECIMAL AND FRACTION

Lady bird [3.3K]

Answer:

Decimal - 25.003

Fraction - $25\frac{3}{1000}$

Step-by-step explanation:

Twenty Five - '25'

And - '.'

3 Thousandths - '.003'

Twenty Five and 3 Thousandths would be 25.003.

For a Fraction:

0.003 = $\frac{3}{1000}$

So 25.003 would be $25\frac{3}{1000}$ .

Hope this helps.

lidiya [134]

Answer:

The inequality a + 8 > 14 can be used to represent the situation.

The remaining side must be longer than 6 cm.

Step-by-step explanation:

The inequality a + 8 > 14 can be used to represent the situation , reason because the summation of the two sides should be greater and not any thing equal to or less than 14

The remaining side must be longer than 6 cm. Reason because we are already given 8, so we must look for a value when added to 8 must be greater than 14.
