The mean service time (x with bar on top ) of a customer at a barber shop is 18 minutes with a standard deviation (sigma ) of 90 seconds. Upper specification limit (USL) is 20 minutes, whereas lower specification limit (LSL) is 15 minutes for this process. Calculate the proper capability metric. Is the process capable

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
