The number of cars running a red light in a day, at a given intersection, possesses a distribution with a mean of 3.6 cars and a

Iteru [2.4K]

Answer:

$X \sim N(3.6,5)$

Where $\mu=3.6$ and $\sigma=5$

Then we have:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

With the following parameters:

$\mu_{\bar X}= 3.6$

$\sigma_{\bar X} = \frac{5}{\sqrt{100}}= 0.5$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the number of cars running a red light of a population, and for this case we know the distribution for X is given by:

$X \sim N(3.6,5)$

Where $\mu=3.6$ and $\sigma=5$

Since the distribution for X is normal then we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

With the following parameters:

$\mu_{\bar X}= 3.6$

$\sigma_{\bar X} = \frac{5}{\sqrt{100}}= 0.5$

How to solve 3+4(-4-2)+5=-16

masha68 [24]

Answer:

-16=-16

Step-by-step explanation:

You would first do (-4-2) which would be (-6), after you would multiply (-6) by 4 which comes out to be -24, after you would add 3 which would look like this -24+3 but since its a negative it would come out to be -21 then you would do the same thing with 5, it would look like this -21 + 5 but since its negative it would be -16. I hope this helped :)

Which of the following describes how to graph the line whose equation is y = x - 1?

jenyasd209 [6]

You would need to substitute a number for y. I would probably put 0 for y which would then give you x.

y = 0

x = 1

Then you can easily graph the point. :)
