Svetradugi [14.3K]

Answer:

P(80

And we can find this probability with this difference:

P(-4

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(-4

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 passengers who arrive at the platform of a population, and for this case we know the following info

Where \mu=180 and \sigma=25

We are interested on this probability

P(80

For this case we can assume that the random variable is normally distributed.

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

P(80

And we can find this probability with this difference:

P(-4

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(-4

What is the equation of a line that is perpendicular to the x-axis and passes through (3,-2)
34kurt

Answer:

x = 3

Step-by-step explanation:

we know that if we have an original line and we are finding the perpendicular we know that the slope of the second line is gonna be the negative reciprocal of the first line and given that we know it must be  perpendicular to the original line it will be heading downwards on the y axis with no slope so instead of y equals it will be x equals and we know that our x value of the point given is three so the answer is x = 3
