An EWMA control chart uses λ = 0.5. What is the value of L such that the control limits of this EWMA control chart in the steady state have the same width with a 3σ X_bar control chart?
Answer:
5.199
Step-by-step explanation:
From the information provided;
We know that λ = 0.5.
However, the control limits for a steady-state EMWA control chart is:
[tex]\mu_o \pm L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
where;
[tex]UCL = \mu_o + L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
[tex]LCL = \mu_o- L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
Given that the data is chosen from an individual sample;
Then; we can express the width as:
[tex]L \sigma \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3 \sigma[/tex]
[tex]L \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(2-0.5)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(1.5)}}= 3[/tex]
[tex]L \sqrt{0.333}= 3[/tex]
[tex]L\times 0.577= 3[/tex]
[tex]L=\dfrac{ 3 }{0.577}[/tex]
L = 5.199

the largest orange in a bag has the circumference of 9 5/8 inches. The smallest orange has a circumference
of 7 13/16 inches. Write the difference of the circumferences of the smallest orange and the largest orange
Answer:
1.81 inches
Step-by-step explanation:
Given that,
The circumference of the largest orange in a bag is [tex]9\dfrac{5}{8}\ \text{inches}[/tex] and that of smallest orange is [tex]7\dfrac{13}{16}\ \text{inches}[/tex].
Difference = largest orange - smallest orange
= [tex]9\dfrac{5}{8}-7\dfrac{13}{16}\\\\=\dfrac{77}{8}-\dfrac{125}{16}\\\\=\dfrac{29}{16}\\\\=1.81\ \text{inches}[/tex]
So, difference of the circumferences of the smallest orange and the largest orange is 1.81 inches
compare the fraction 3/5 to 1/2
Answer:
1 / 2 is smaller than 3 / 5.
Step-by-step explanation:
Compare 1/2 and 3/5. 1 / 2 is smaller than 3 / 5. Steps for comparing fractions. Find the least common denominator or LCM of the two denominators: LCM of 2 and 5 is 10; For the 1st fraction, since 2 × 5 = 10, 1 / 2 = 1 × 5 / 2 × 5 = 5 / 10; Likewise, for the 2nd fraction, since 5 × 2 = 10, 3 / 5 = 3 × 2 / 5 × 2 = 6 / 10 Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

Which expression represents the perimeter of the rectangle shown below
Answer:
D. 2x² + 10x - 2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = x² + 3x - 2
Width = 2x + 1
Perimeter = 2(x² + 3x - 2 + 2x + 1)
Perimeter = 2(x² + 5x - 1)
Perimeter = 2(x²) + 2(5x) - 2(1)
Perimeter = 2x² + 10x - 2

PLZ GIVE BRAINLIEST AND PUSH THANKS BUTTON IM IN A BET ABOUT WHOEVER WINS GETS $50
Side lengths form a triangle that is similar to triangle ABC are 30, 21, 45 and this can be determined by using the given data.
Given :
Triangle ABC.AB = 10AC = 15BC = 7The following steps can be used in order to determine the side lengths form a triangle that is similar to triangle ABC:
Step 1 - First determine the ratio of the length of AB and AC.
[tex]\rm \dfrac{AB }{AC} = \dfrac{10}{15}[/tex] --- (1)
Step 2 - Now, determine the ratio of the length of AC and BC.
[tex]\rm \dfrac{AC }{BC} = \dfrac{15}{7}[/tex] --- (2)
Step 3 - Determine the ratio of the length of BC and AB.
[tex]\rm \dfrac{AB }{BC} = \dfrac{10}{7}[/tex] --- (3)
Step 4 - Now, check the ratio of the side lengths given in option A).
[tex]\dfrac{30}{21}=\dfrac{10}{7}[/tex] (Similar to expression 3)
[tex]\dfrac{45}{21}=\dfrac{15}{7}[/tex] (Similar to expression 2)
[tex]\dfrac{30}{45}=\dfrac{10}{15}[/tex] (Similar to expression 1)
Therefore, the correct option is A).

Recall that profit can be computed in terms of revenue and cost. Assume that the annual widget sales match the annual widget demand and annual widget production. Construct a model for profit using the models for revenue and cost that you found in the Revenue and Cost sections. Find the model for profit P ( x ), where P ( x ) is the total annual profit in dollars for x widgets sold, and write it as P ( x ) = a x 2 + b x + c. Note: You are using the fact that P ( x ) = R ( x ) − C ( x ), not creating a table of data.

Answer:
value of c is -73.4
Step-by-step explanation:
When you subtract revenue from cost the Profit model becomes
P(x)= -0.956x^2 + 106.2x - 73.4
