Answer:
3.6% of the ball bearings will have diameters of 20.27 mm or more.
Step-by-step explanation:
We can calculate this proportion using the z-score.
We have a normal distribution with mean 20.00 mm and standard deviation of 0.150 mm.
The value for X is 20.27 mm.
Then, the z-score and its associated probability are:

I believe the points should be as follows : X, S, Y, and U.
I think the answer is 1248 because if you divide 936 by 3 you get 312. since that is the number you mulitply to get 936 i multiplyed 312 by 4 to the the answer
Answer:
5/39
Step-by-step explanation:
10divided by 78 is 10/78.
you can simplify it to 5/39
this is the simplest form
