0.125 the first one, even though im not sure.
Answer:
solution given:
height [h]= 20 millimetres
radius [r]=20 millimetres
π=3.14
now
Volume of cylinder [V]=πr²h=3.14×20²×20=25120mm³is your answer.
Answer:
a) 
And using the normal distribution table or excel we got:

b) 
And we can use the normal standard table or excel in order to find the probability and we got:

Step-by-step explanation:
For this case we know that the random variable of interest is normally distributed with the following parameters:

Part a
We want to find this probability:

And we can use the z score formula given by:

Replacing we got:

And using the normal distribution table or excel we got:

Part b
We select a random sample of size n = 16 and we try to find this probability:

And we can use the z score formula given by:

And replacing we got:

And we can use the normal standard table or excel in order to find the probability and we got:

Answer:
For example, the function
does not have a y-intercept of (0, 1). To prove this, let's make x=0, and if the value of 'y' is different from 1, then, the graph does nt have a y-intercept of (0,1):
⇒
⇒ 
Therefore, the y-intercept is at (0, 0) not (0, 1).
