deff fn [24]

Answer:

For this process, the capability index is 0.4444

Step-by-step explanation:

Given the data in the question;

Lower specification limit = 22.8 mm

Upper specification limit = 23.2 mm

The standard deviation σ = 0.15 mm

Mean μ = 23

capability index Cpk = ?

Now, Using the formula;

Cpk = min{ [(USL - μ)/3σ], [(μ - LSL)/3σ]

where USL is the Upper specification limit, LSL is the Lower specification limit, σ is the standard deviation, μ is the mean

so we substitute

Cpk = min{ [(23.2 - 23 )/(3×0.15)], [(23 - 22.8)/(3×0.15)] }

Cpk = min{ [0.2 / 0.45 ], [0.2 / 0.45] }

Cpk = min{ [ 0.4444 ], [0.4444] }

Therefore, for this process, the capability index is 0.4444

Which inequality does the graph below represent?

Dima020 [189]

Answer:

A. $y\le2x^2-8x+3$

Step-by-step explanation:

The given parabola has vertex at (2,-5).

The equation of this parabola in vertex form is given by:

$y=a(x-h)^2+k$ , where (h,k)=(2,-5) is the vertex of the parabola.

We substitute the values to get:

$y=a(x-2)^2-5$

The graph passes through; (0,3).

$3=a(0-2)^2-5$

$\implies 3+5=4a$

$\implies 8=4a$

$\implies a=2$

Hence the equation of the parabola is

$y=2(x-2)^2-5$

We expand this to get:

$y=2x^2-8x+8-5$

$y=2x^2-8x+3$

Since the outward region was shaded, the corresponding inequality is

$y\le2x^2-8x+3$

The correct answer is A

(Four-fifths + three-fifths) + 3.5 times 5

defon

Answer:

18.9

Step-by-step explanation:

First, lets solve for the fractions. You can divide the fractions from the top, to their bottom (4 divided by 5, 3 divided by 5), in this case, you get 1.4. Now you have to rewrite the problem: 1.4+3.5x5. You solve it, and get 18.9.
