Step-by-step explanation:

Answer:

Kindly check explanation

Step-by-step explanation:

Xbar = 0.3015 ; Rbar = 0.00154

USL = 0.295 ; LSL = 0.305

For a subgroup size of 3 ; k = 3 ; d2 = 1.693

The mean = xbar = 0.3015 mm

The standard deviation = Rbar / d2 = 0.00154 / 1.693 = 0.0009096

b) Suppose that parts below the LSL can be reworked, but parts above the USL must be scrapped. Estimate the proportion of scrap and rework produced by this process.

P(X < 0.295)

(x - mean) / standard deviation

(0.295 - 0.3015) / 0.0009096 = 0.00003

0.00003 should be reworked.

P(X > 0.305)

1 - P(X < 0.305)

(x - mean) / standard deviation

(0.305 - 0.3015) / 0.0009096 = 3.847

1 - P(Z < 3.847)

1 - 0.99994

= 0.00006

0.00006 should be reworked.

c) Suppose that the mean of this process can be reset by fairly simple adjustments. What value of the process mean would you recommend? Estimate the proportion of scrap and rework produced by the process at this new mean.

Recommended mean = 0.3000 mm

P(X < 0.295)

(x - mean) / standard deviation

(0.295 - 0.3000) / 0.0009096 = 0.00003

0.00003 should be reworked.

P(X > 0.305)

1 - P(X < 0.305)

(x - mean) / standard deviation

(0.305 - 0.3000) / 0.0009096 = 5.497

1 - P(Z < 5.497)

1 - 0.99997

= 0.00003

0.00003 should be reworked.

Answer:

n=3

Step-by-step explanation:

distribute, then add 3 to both sides, then divide both sides by 3

Answer:

n = 3

Step-by-step explanation:

3(n−1)=6

Step 1: Simplify both sides of the equation.

3(n−1)=6

(3)(n)+(3)(−1)=6(Distribute)

3n+−3=6

3n−3=6

Step 2: Add 3 to both sides.

3n−3+3=6+3

3n=9

Step 3: Divide both sides by 3.

3n/3  = 9/3\

n= 3

Answer:

The Average rate of change of function f(x)

A(x) = 3

Step-by-step explanation:

Step(i):-

Given function f(x) = x²-2

Given values x = a = -1 and  x = b =4

The Average rate of change of function f(x)

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

Given function f(x) = x²-2

                f(a) =f(-1) = (-1)²-2 = 1-2 = -1

                f(b) = f(4) = (4)²-2 = 16-2 = 14

Step(ii):-

The Average rate of change of function f(x)

[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]

[tex]A(x) = \frac{14-(-1)}{4-(-1)} = \frac{14+1}{4+1} = \frac{15}{5} =3[/tex]

Final answer:-

The Average rate of change of function f(x)

A(x) = 3

6.82.26v375 is the descreasing order

Answer:

it is c, 6.82 2pi 55/9 sq37

Step-by-step explanation:

Option C is correct, the value of y is 8 square root of 2.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We need to find the value of y.
The given triangle is right angle triangle with opposite side of 8 inches.

Hypotenuse is y and adjacent side is x.

Now let us solve for sinB

sin45 =8/y

1/√2=8/y

Apply cross multiplication

y=8√2

8 square root of 2

Hence, option C is correct, the value of y is 8 square root of 2.

Answer:

1 AM = 58 Degrees

9 AM = 76 Degrees

Difference of temperate between the times:

18 Degrees

Divide every hour that passes by the total difference of temperate, which the hours are: 2, 3, 4, 5, 6, 7, 8, 9

18 / 8 = 2.25

Which means, the rate of change in degrees per hour is 2.25 degrees.
