Design specifications require that a key dimension on a product measure 105 ± 12 units. A process being considered for producing
marta [7]

Answer:

Cpk = Cpu = Cpl = 0.4785

Step-by-step explanation:

Solution:-

- The capability of a process is determined using the capability index ( Cpk ). The index helps in determining the output of the process lies within the specification limits.

- The key dimension on a product measure is:

                                 105 ± 12 units

- Process is producing this product at a 6-sigma quality standards i.e ( process is producing this product has a standard deviation (σ) of three units.)

Where,         Standard Error in measured value = 12 units.

- The process capability (Cpu) is defined based on the Upper Specification Limit of the process (USL):

                             Cpu = (USL - u) / 3σ

- The process capability (Cpl) is defined based on the Lower Specification Limit of the process (LSL):

                             Cpl = ( u - LSL) / 3σ

- Assume that the process is centered with respect to specifications, then the given absolute value of u = 105 units.

Where the specification limits are defined as:

                             LSL = u - SE = 105 - 12

                             LSL = 93 units

                             USL = u + SE = 105 + 12

                             USL = 117 units

- Now evaluate the Process capability on each of the two limits specification limits:

                           Cpu = (USL - u) / 3σ

                           Cpu = (117 - 105) / 3σ

                           Cpu = 4 / σ

                           Cpl = ( u - LSL) / 3σ

                           Cpl = ( 105 - 99 ) / 3σ

                          Cpl = 4 / σ    

- The minimum of Cpu and Cpl is denoted as the Cpk value:

                           Cpk = min ( Cpu , Cpl )

                           Cpk = Cpu = Cpl = 4 / 8.36

                           Cpk = Cpu = Cpl = 4 / 8.36 = 0.4785

Luis es repartidor de leche el tiene 534 bolsas y las reparte entre cierto numero de tienda de modo que a cada le corresponde 28
OlgaM077 [116]
The first thing we must keep in mind is that there are 2 bags left over.
 Therefore, Luis distributed:
 534-2 = 532
 The number of bags will be:
 N = (total amount distributed) / (amount distributed per store)
 Substituting we have:
 N = (532) / (28)
 N = 19
 Answer:
 
Luis distributed milk for 19 stores.

Kaylis [27]

Answer:

  3π

Step-by-step explanation:

Arc length is given in terms of central angle θ in radians as ...

  s = rθ

For r = 27 and θ = (20/180)π, the arc length is ...

  s = (27)(20/180)π = 3π

The arc length is 3π units.
