Given: PQ ⊥ QR , PR=20, SR=11, QS=5 Find: The value of PS.

Neporo4naja [7]

1. PQR and is a right triangle, so you can calculate the measure of PQ by applying the Pythagorean Theorem. PR is the hypotenuse and QR and PQ are the legs:

$PR^{2}=PQ^{2}+QR^{2}\\ PQ=\sqrt{PR^{2}-QR^{2}}\\ PQ=\sqrt{20^{2}-16^{2}} \\ PQ=12$

2. PQS and is a right triangle too, so you can calculate the measure of PS by applying the Pythagorean Theorem as above. PS is the hypotenuse and PQ and QS are the legs:

$PS=\sqrt{PQ^{2}+QS^{2}}=13$

Therefore, the answer is: The value of PS is 13.

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

please help will give brainlest+30 points Snowy's Snow Cones has a special bubble gum snow cone on sale. The cone is a regular s

natali 33 [55]

Answer:

Hello There!

`~~~~~~~~~~~~~~~~~~~~~

If you subtract the volume of the sphere from the cone, you'll get the volume you can fill with flavored ice. Right?

$Volume (sphere) = \frac{4}{3}\pi r^3$

$Volume(sphere) = \frac{1}{3}\pi r^2 . h$

So that means, The volume left to put in flavored ice is :

$Volume(sphere) = \frac{1}{3}\pi r^2h - \frac{4}{3}\pi r^2$

So putting in the value for radius and height of the cone and radius of the sphere in the 2nd term will do the thing, I think.

.......

Okay, I think they didn't raise the power but wrote the exponent beside the number. It must be c. They wrote 32 so as to say 3^2 and wrote 0.553 to say (0.55)^3

So the answer is (C)

Hope this helped you. Brainliest would be nice!

Olenka [21]

For this case, the first thing we must do is define variables.

We have then:

d: number of dimes

q: number of quarters

We now write the system of equations that models the problem.
