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

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
