neonofarm [45]
5/20 students in Alessandro's class live in Oakdale, which can be simplified to 1/4. 1/4 in decimal form is 0.25. Now to convert it to a percentage, you just multiply that by 100. So 25% of students in Alessandro's class live in Oakdale.

A Starbucks coffee shop serves an average of 3500 customers per day, with a standard deviation of 250. What is the probability t
castortr0y [4]

Answer:

P(3300  

And we can find this probability with this difference:  

P(-0.8  

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 amount of cofee shops of a population, and for this case we know the distribution for X is given by:  

X \sim N(3500,250)  

Where \mu=3500 and \sigma=250  

We are interested on this probability  

P(3300  

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(3300  

And we can find this probability with this difference:  

P(-0.8

Solve the equation <br>8-2x=-8x+14
Marina86 [1]

8 - 2x = -8x + 14      <em>subtract 8 from both sides</em>

-2x = -8x + 6     <em>add 8x to both sides</em>

6x = 6     <em>divide both sides by 6</em>

<h3>x = 1</h3>
