If it didn't have that piece cut out on the bottom, it would be a rectangle that's 9cm wide and 5cm high. Its area would be 9x5= 45 cm².

But that piece is cut out of the bottom. The cut-out piece is 3cm wide and 3cm high, so its area is 3x3= 9 cm².

9 cm² have been cut out of the 45 cm² of the complete big rectangle. So the remaining area of the figure is 45 - 9 =<em> 36 cm²</em> .

A process produces a certain part with a mean diameter of 2 inches and a standard deviation of 0.05 inches. The lower and upper

Nimfa-mama [501]

Answer:

The value of Cp (measure of potential capability) is 6.33.

Step-by-step explanation:

Given information: Process average = 2 inches, process standard deviation = 0.05 inches, lower engineering specification limit = 1.6 inches and upper engineering specification limit =3.5 inches.

The formula for Cp (measure of potential capability) is

$CP=\frac{USL-LSL}{6\sigma}$

Where, USL is upper specification limit, LSL is specification limit, σ is process standard deviation.

Substitute USL=3.5, LSL=1.6 and σ=0.05 in the above formula.

$CP=\frac{3.5-1.6}{6(0.05)}$

$CP=\frac{1.9}{0.3}$

$CP=6.3333$

$CP\approx 6.33$

Therefore the value of Cp (measure of potential capability) is 6.33.

Solve the combined inequality x + 3 > -5 and -4x ≥ -16 showing all of your work

ad-work [718]

Well for the first one you have to subtract 3 on both sides so that would make the equation x > -8 (because a negative subtracting a positive is basically a negative plus negative) and so your equations done. For the second one you divide both ides by -4 so your equation would be x < 4 (the sign would be less then or qual to because you divided by a negative)
