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.

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

Answers

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

Answers

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

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?

Answers

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

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 = 7

The 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).

Which expression represents the perimeter of the rectangle shown below

Answers

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
