For 50 consecutive days, a process engineer has measured the weight of a component after it has been coated with special paint.

Each day, she takes a sample of 10 components. The average across all 500 components is 45.343019 grams. The average range across all parts is 0.0076382 grams. When constructing an X-bar chart, what would be the centerline, and what would be the upper and lower control limits

Answer:

UCL (X-bar) = X mean+ (A2 x R-bar)

LCL (X-bar) = X mean -(A2 x R-bar)

Center line = Mean

A2 for sample size of 10 = 0.308

X mean = 45.343019

R bar = Average of range = 0.0076382

UCL (X-bar) =45.343019+(0.308*0.0076382) = 45.3453715656 grams

LCL (X-bar) = 45.343019-(0.308*0.0076382) = 45.3406664344 grams

Center line = Mean = 45.343019

Suppose you're adding 43 and 28 will you regroup? explain
Mrac [35]
Yes, since 43 is the bigger number, but in each number's ones place 8 is larger than 3, so you would have to regroup in the ones place.

Mila [183]

Answer:

<em>(-3/5, 29/5) </em>

Step-by-step explanation:

Given the simultaneous equation;

-3x+4y=25...... 1

y= -3x+4 ..... 2

We are to confirm if (-3, 4) is the solution to the equations;

Substitute equation 2 into 1;

From 1;

-3x+4y=25

-3x + 4(-3x+4) = 25

-3x -12x + 16 = 25

-15x = 25 - 16

-15x = 9

x = -9/15

x = -3/5

Substitute x = -3/5 into equation 2 to get y;

From 2;

y= -3x+4

y = -3(-3/5)+4

y = 9/5 + 4

Find the LCM

y = (9+20)/5

y = 29/5

<em>Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.</em>
