What is the GCF of 44 and 110?

TEA [102]

In order to find the GCF of these two numbers we need to list all their factors and find the first common one so.

44: 1,2,4,11,22,44
110, 1,2,5,10,11,22,55,110

Since 22 is the highest number that both share and its common, that would be your answer. Answer: 22.

The amount of Jen’s monthly phone bill is normally

vredina [299]

Answer:

$P(19$

And we can find this probability with this difference and using the normal standard distribution

$P(-3$

Step-by-step explanation:

Let X the random variable that represent the amount of Jen monthly phone of a population, and for this case we know the distribution for X is given by:

$X \sim N(55,12)$

Where $\mu=55$ and $\sigma=12$

We are interested on this probability

$P(19$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

Replacing the info we got:

$P(19$

And we can find this probability with this difference and using the normal standard distribution

$P(-3$

Is this a function idk also what's the domain and range

masya89 [10]

This is a function since it passes the vertical line test. It is impossible to draw a single vertical line to have it pass through more than one point on the curve.

The domain is the set of numbers x such that x is between -3 and +3 excluding those endpoints. In other words, the domain is -3 < x < 3. We never actually get to either endpoint because of the vertical asymptotes.

The range is the set of all real numbers. It is possible to get any output we want depending on the specific input.
