Because it is equal to three, it is a straight line going up from 3. You don’t need to shade anything like in the picture, just need a straight line going up from the 3.

For a more complex project, statistical analysis can be applied to a Control Chart to identify potential causes of schedule devi

Ierofanga [76]

Answer: True

The control chart is graph,that is used to study how a process changes over time with date plotted in time order.

Control charts are a valuable tool for monitoring process performance. However, you have to be able to interpret the control chart for it to be of any value to you.

A control chart can use to measure schedule Trends.

Step-by-step explanation: in the situation where schedule changes control chart can be use to monitor the process.

The control chart can also serve as guide that helps to notify in case of changes.

When given the information below, can you conclude that Quadrilateral WXYZ is a parallelogram? Why or why not?

Masja [62]

B) No, because opposite sides are not parallel

Step-by-step explanation:

Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;

Parallel sides to be : WX // YZ and XY // WZ

Additionally, we know parallel sides have equal gradient thus;

The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ

However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.

Minimum Average Cost

Dahasolnce [82]

Answer:

a) $\bar{C}(x)=\dfrac{100}{x}+25-120\dfrac{lnx}{x}$

b) $\bar{C}(x)=5.81$

Step-by-step explanation:

Given that

C = 100 + 25 x - 120 ln x ,x ≥ 1.

The average cost function given as

$\bar{C}(x)=\dfrac{C(x)}{x}$

$\bar{C}(x)=\dfrac{100 + 25 x - 120 \ln x}{x}$

$\bar{C}(x)=\dfrac{100}{x}+25-120\dfrac{lnx{x}$

Therefore

$\bar{C}(x)=\dfrac{100}{x}+25-120\dfrac{lnx}{x}$

To find average minimum cost

$\bar{C}(x)=\dfrac{100}{x}+25-120\dfrac{lnx}{x}$

$\dfrac{d\bar{C}(x)}{dx} = -\dfrac{100}{x^2} +0-120\times \dfrac{1-lnx}{x^2}$

$0 = -\dfrac{100}{x^2} +0- 120\times \dfrac{1-lnx}{x^2}$

100 + 120 (1-lnx) = 0

$lnx=\dfrac{220}{120}$

ln x =1.833

$x=e^{1.833}$

x=6.25

$\bar{C}(x)=\dfrac{100}{6.25}+25-120\dfrac{ln6.25}{6.25}$

$\bar{C}(x)=5.81$

Explain how you find the average rate of change for a linear function.<br><br> PLEASE

Olin [163]

Step-by-step explanation:

The average rate of change is constant for a linear function. Another way to state this is that the average rate of change remains the same for the entire domain of a linear function. If the linear function is y=7x+12 then the average rate of change is 7 over any interval selected. y=mx+b , where m is the slope.
