Logan's e-reader sent a notification saying that he has completed 75% of the e-book.
Vika [28.1K]

Answer:

The total number of pages in the e-book is 240.

Step-by-step explanation:

Given:

Logan has completed 75%

Logan has read 180 pages

To Find:

The total number of pages in the e-book= ?

Solution:

Let X be the total number of pages on the e-book

then

=> 75% of X = 180

Now lets find the value of X

X = \frac{180}{75\%}

X = \frac{180}{\frac{75}{100}}

X = \frac{180}{0.75}

X = 240

Suppose an electronics manufacturer takes a sample of 5000 devices produced by an assembly line. Each device is inspected or tes
Deffense [45]

Answer:

DPMO = 40

Does not meet Six Sigma goals

Step-by-step explanation:

If there are 40 possible defects in each of the 5,000 devices, the number of defect opportunities is:

n=5,000*40\\n=200,000\ opportunities

If 8 total defects were found, the DPMO for the sample is:

DPMO = \frac{8}{200,000}*1,000,000\\DPMO = 40

Six Sigma aims to reduce defects to 3.4 Defects Per Million Opportunities, since the DPMO is higher than 3.4, the process does not meet Six Sigma goals.

؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟
BigorU [14]

Answer:

a) ∠XWY = 53°

b) ∠XZY = 106°

Step-by-step explanation:

The relationship between the central angle and the arc length is that they're equal. So, if arc XY = 106° this means that ∠XZY = 106°.

The relationship between the central angle ∠XZY and the inscribed angle ∠XWY is that the inscribed angle is half the value of the central one.

So, ∠XWY= ∠XZY/2 = 106/2 = 53

<u>Results:</u>

∠XWY = 53°

∠XZY = 106°
