Answer:

1a) UCL = 14.2

    LCL = 10.9

b) UCL = 15.63

    LCL = 9.37

c) UCL = 16.48

   LCL = 8.52

2) The difference between the limits falls close together as n increases

and the difference between the limits  falls farther away from 12.5

Step-by-step explanation:

mean ( μ ) = 12.5

std ( б ) = 1.1

UCL = μ + ( n - 1 ) б / √n

LCL = μ - ( n - 1 ) б / √n

1) a) Given  n = 4

UCL = 12.5 + ( 3 ) * 1.1 / 2

       = 12.5 + 3.3/2 = 14.15 ≈ 14.2

LCL = 12.5 - 3.3/2 = 10.85 ≈ 10.9

b) Given n = 10

UCL = 12.5 + ( 9 ) * 1.1 /√10

       = 12.5 + 3.13 = 15.63

LCL = 12.5 - 3.13 = 9.37

c) Given n = 15

UCL = 12.5 + 14 * 1.1 / √15

       = 12.5 + 3.98 = 16.48

LCL = 12.5 - 3.98 = 8.52

2) As the sample size increases the difference between the limits of the control chart decreases

Hence the difference falls close together as n increases

and the difference between the limits  falls farther away from 12.5

Which of the following absolute value equations has no solutions?Group of answer choices
Amiraneli [1.4K]

The absolute value measures the distance a number is away from the origin (zero) on the number line. A number can be to the left or right of zero on the number line, but the distance away from zero is always positive. Graphically:

In other words:

• If d is positive and

\begin{gathered} |x|=d \\ \text{ then} \\ x=d\text{ or }x=-d \end{gathered}

• If d is negative and

\begin{gathered} |x|=-d \\ \text{then} \\ \text{ No solution, because distance (d) can not be negative.} \end{gathered}

Therefore, the equation that has no solutions is:

\boldsymbol{|x|=-3}

A line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is:
rewona [7]

A line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of circle.

Since,

The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.

The diameter is the length of the line through the center that touches two points on the edge of the circle.

So, we can say that every diameter of a circle is always called chord (longest chord) but every chord of the circle is not a diameter because the diameter passes to the circle's center but it not necessay that evey chord will pass through the center of the circle. Some, line segment goes from one side of the circle to the other side and doesn't pass through centre then for this case the line segment is called chord of the circle.

Hence, a line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of the circle.

10 is 8% of a, and 5 is 4% of b. c equals b/a. What is the value of c?? step by step explanation pls...
klio [65]

Answer:

c = 1

Step-by-step explanation:

"10 is 8% of a":     0.08a = 10, or <u>a = (10/0.08)</u>

"5 is 4% of b":      0.04b =  5, or <u>b = (5/0.04)</u>

"c equals b/a":       c = (b/a)

----

What is the value of c?

c = (b/a)

c = ((5/0.04)/(10/0.08))

c = (5/0.04)*(0.08/10)

c = (5/10)*(0.08/0.04)

c = (1/2)*(2)

<u>c = 1</u>
