Step-by-step explanation:

Cylinder volume formula is \pi r^2h

\pi \times 6^2 \times h=904.78

36\pi \times h=904.78

h=904.78 \div 36\pi

If you get a sneak peak at the salary list of your job and realize you are in the lowest bracket, which is the lowest 1%, what i
hoa [83]

Answer:

z=-2.33

And if we solve for a we got

a=48000 -2.33*5500=35185

And for this case the answer would be 35185 the lowest 1% for the salary

Step-by-step explanation:

Let X the random variable that represent the salary, and for this case we can assume that the distribution for X is given by:

X \sim N(48000,5500)  

Where \mu=48000 and \sigma=5500

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

P(X>a)=0.99   (a)

P(X   (b)

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 0.01 of the area on the left and 0.99 of the area on the right it's z=-2.33. On this case P(Z<-2.33)=0.01 and P(z>-2.33)=0.99

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=-2.33

And if we solve for a we got

a=48000 -2.33*5500=35185

And for this case the answer would be 35185 the lowest 1% for the salary

Find the z-score such as 88% of the area under the normal curve is to the left of the z-score
jok3333 [9.3K]
If you have a calculator with statistical functions, that's the way to go.

On my TI-83, I typed in  invNorm(0.88) and got the result z = 1.17.

88% of the area under the normal curve is to the left of z = 1.17.
