Answer:

113.098

Step-by-step explanation:

Area of a semicircle is πr^2 / 2

so π*144 / 2

which is 226.195

area of smaller circle is:

π*36 (r=6)

that is 113.097

226.195-113.097 is

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.

Answer:

This is acute angle since 75° < 90°

This is an isosceles triangle

<u>Exterior angle is the sum of non-adjacent interior angles:</u>

4x + 7 + 6x - 9 = 118
10x - 2 = 118
10x = 120
x = 12

m∠L = 4*12 + 7 = 48 + 7 = 55°

<u>The triangles are congruent and corresponding sides are equal:</u>

3x - 5 = 2x + 1
3x - 2x = 1 + 5
x = 6

<u>Side lengths are:</u>

3*6 - 5 = 13
