A quality control chart is used to monitor the customer wait time at a local call center. Sample means of five times are averaged and plotted over time. The last 50 sample means are randomly distributed between the upper and lower control limits. The process is _______.

Answers

Answer 1

Answer:

Answer:

in-control

Step-by-step explanation:

basically, their are 2 types of control charts delineated:

1) uni-variate control chart : shows one quality characteristic

2)multivariate control chart : shows 2 or more than two quality characteristics

in statistics, we have "upper control limit" and "lower control limit".

if the system/variables are within these limits it is 'in-control' other wise 'out of control'

in-controlsays that all dots are within control limit and they have random pattern.

To find f(-5), substitute x by 5 in the function above

$\begin{gathered} f(-5)=(--5-1)^2+3 \n f(-5)=(5-1)^2+3 \n f(-5)=(4)^2+3 \n f(-5)=16+3 \n f(-5)=19 \end{gathered}$

To find f(6), substitute x by 6 in the function above

$\begin{gathered} f(6)=(-6-1)^2+3 \n f(6)=(-7)^2+3 \n f(6)=49+3 \n f(6)=52 \end{gathered}$

The answers:

f(-5) = 19

f(6) = 52

The machinist's goal was to increase his production by at least 10% each day. Assume he achieved his goal. If he was able to machine 25 items on Tuesday, how many would he machine on Wednesday?

Answers

Answer:

The number of machine produced on Wednesday is 27.5.

Step-by-step explanation:

It is given that the number of machines produced by machinist on Tuesday is 25.

The machinist's goal was to increase his production by at least 10% each day.

Therefore the number of produced machines on Wednesdays is 1% more than the number of machines produced on Tuesday.

$\text{10 \% of 25}=(10)/(100)* 25=2.5$

The number of machine produced on Wednesday is,

$25+2.5=27.5$

Therefore the number of machine produced on Wednesday is 27.5.

25+10%= 27.5 Hope this helps.

Answer with Step-by-step explanation:

Given

$f(x)=(1-cos(2x))/(1-cos(x))\n\n\lim_(x \rightarrow 0)f(x)=\lim_(x\rightarrow 0)(\frac{1-(cos^2{x}-sin^2{x})}{1-cos(x)})\n\n(\because cos(2x)=cos^2x-sin^2x)\n\n\lim_(x \rightarrow 0)f(x)=\lim_(x\rightarrow 0)((1-cos^2x)/(1-cos(x))+(sin^2x)/(1-cosx))\n\n=\lim_(x\rightarrow 0)(((1-cosx)(1+cosx))/(1-cosx)+(sin^2x)/(1-cosx))\n\n=\lim_(x\rightarrow 0)((1+cosx)+(sin^2x)/(1-cosx))\n\n\therefore \lim_(x \rightarrow 0)f(x)=1$

3x+7x−28+31−8x for x=2043
Simplified expression-?
Value-?

Answers

The expression 3x + 7x - 28 + 31 - 8x simplifies to 2x + 3. When x equals 2043, the value of the Simplifying Expression is 4089.

The given expression is 3x + 7x - 28 + 31 - 8x.

To simplify the expression, we first group together the like terms.

Thus, the expression becomes (3x + 7x - 8x) + (31 - 28).

This simplifies further to 2x + 3.

Next, to find the value of the expression for x = 2043, we substitute 2043 for x into the simplified expression, resulting in 2*2043 + 3 = 4089.

Therefore, the simplified version of the expression is 2x + 3 and the value of the expression for x = 2043 is 4089.

6.Valdez Construction signed a note with a payment of $5,200 per quarter for 5 years.
Find the amount they must set aside today to satisfy this capital requirement in an account earning 8% compounded quarterly.

$30,506.32

$126,346.32

$51,054.38

$85,027.44

Answers

If P = Periodic payments done quarterly (that is, four time in a year) = $5,200, n = number of years (5), R = Annual interest rate = 8% = 0.08, and A = Amount to be set aside today, then

A = P [1-(1+R/4)^4n]/(R/4) = 5200 [1-(1+0.08/4)^4*5]/(0.08/4) = $85,027.45

Therefore, Valdez construction should set aside $85,027.44 now to satisfy the capital requirement.

Brawdy Plastics, Inc., produces plastic seat belt retainers for General Motors at the Brawdy Plastics plant in Buffalo, New York. After final assembly and painting, the parts are placed on a conveyor belt that moves the parts past a final inspection station. How fast the parts move past the final inspection station depends upon the line speed of the conveyor belt (feet per minute). Although faster line speeds are desirable, management is concerned that increasing the line speed too much may not provide enough time for inspectors to identify which parts are actually defective. To test this theory, Brawdy Plastics conducted an experiment in which the same batch of parts, with a known number of defective parts, was inspected using a variety of line speeds. The following data were collected. If required, enter negative values as negative numbers.Line Speed Devective number20 2320 2130 1930 1640 1540 1750 1450 11a.
