he accounts receivable department at Rick Wing Manufacturing has been having difficulty getting customers to pay the full amount

of their bills. Many customers complain that the bills are not correct and do not reflect the materials that arrived at their receiving docks. The department has decided to implement SPC in its billing process. To set up control​ charts, 10 samples of 50 bills each were taken over a​ month's time and the items on the bills checked against the bill of lading sent by the​ company's shipping department to determine the number of bills that were not correct. The results​ were: Sample No. 1 2 3 4 5 6 7 8 9 10 No. of Incorrect Bills 9 2 14 1 3 2 3 4 9 0 ​a) The value of mean fraction defective ​(p overbar​) ​= nothing ​(enter your response as a fraction between 0 and​ 1, rounded to four decimal​ places).

Answer:

0.094 or 9.4%

Step-by-step explanation:

We have to compute the proportion of defective bills in each batch and then calculate a weighted average.

Let first construct a table like the one attached (see picture)

The value of the mean fraction defective is

\large \bar p = \frac{47}{500}=0.094=9.4\%

The product of twice a number and two is the same as the difference of three times the number and 1/2. find the number.
Daniel [21]
The equation would be 2n x 2 = 3n - 1/2.

So, combine like terms to make it 4n = 3n - 1/2. Subtract to get n = -1/2.

Your answer is -1/2.

The graph shows how the mass of copper
Alex777 [14]

Answer: 8 1/4g/cm³

Step-by-step explanation:

Given the graph :

The rate of change in the mass of copper with respect to volume :

To obtain this, we find the slope or gradient of the graph:

Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)

Drawing a right angled triangle on the anybpart of the line of best fit:

y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2

(y2 - y1) / (x2 - x1)

= (40 -16) / (4.75 - 2)

= 24 / 2.75

= 2400/275

= 8.727 g/cm^3

Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³

Prove system has more than one solution then it has infinite solution
Anarel [89]
This statment only works for linear systems because in non-linear systems it is okay to have more than one soultion
but if the system is linear than you can define it by it two soultions or in other words it takes two points to form a line and if two lines pass through the same points then you can define them by those point and they are the same line

Which table represents a direct variation function?
Luda [366]
Direct variation is y=kx where k is a constant

the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation


the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so

see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it




2nd is increase and y decrease, so not direct variation

3rd is x is same but y increase so nope

4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k

-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true

answer is last option
