Vail Resorts pays part-time seasonal employees at ski resorts on an hourly basis. At a certain mountain, the hourly rates have a
notsponge [240]

Answer:

z=0.842

And if we solve for a we got

\mu=13.16 +0.842*3=15.69

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 hourly rates of a population, and for this case we know the distribution for X is given by:

X \sim N(\mu,3)  

For this part we want to find a value a, such that we satisfy this condition:

P(X>13.16)=0.20   (a)

P(X   (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.80 of the area on the left and 0.20 of the area on the right it's z=0.842. On this case P(Z<0.842)=0.8 and P(z>0.842)=0.20

If we use condition (b) from previous we have this:

P(X  

P(z

But we know which value of z satisfy the previous equation so then we can do this:

z=0.842

And if we solve for a we got

\mu=13.16 +0.842*3=15.69

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. −5x − 25 = 78 Step 1
raketka [301]
Hi there! Her mistake is in step 1.

She subtracted -25 by 25. -25 - 25 = -50

What she SHOULD have done was add 25 to each side. This obeys the property of reciprocals.

-25 + 25 = 0

Hope this helps.

Find the values of the variables
ki77a [65]

The values of the variables are k = -6 , w = ± 9 , f = -7

Step-by-step explanation:

To solve these problems we will compare the elements inside the [  ]

[-12 , -w²] = [2k , -81]

[2f , 3] =  [-14 , 3]

That mean:

1. -12 = 2k

2. -w² = -81

3. 2f = -14

∵ 2k = -12

Divide both sides by 2 to find k

∴ k = -6

∵ -w² = -81

Divide both sides by -1

∴ w² = 81

Take √ for both sides

∴ w = ± 9

∵ 2f = -14

Divide bith sides by 2

∴ f = -7

The values of the variables are k = -6 , w = ± 9 , f = -7
