This is what I would do.

The general formula for the circumference of a circle is

$2\pi \: r$

where r is the length of the radius of the circle. Simply use the formula to find r so that you can draw the circle:

$2\pi \: r = 3.14 ^{2} inches \\ r = \frac{3.142 ^{2} }{2\pi} = 1.571 \: inches$

Now, draw a circle with a radius of 1.571 inches. This number has been rounded up to 3 significant figure. Hope this helps!

Company 1: 3.4 defects per 980,000 occurrences Company 2: 4 defects per 1,115,783 occurrences Company 3: 18 defects per 5,999,52

Gelneren [198K]

Given Information:

Company 1: defects = 3.4

Company 1: units = 980,000

Company 2: defects = 4

Company 2: units = 1,115,783

Company 3: defects = 18

Company 3: units = 5,999,521

Required Information:

six-sigma level = ?

Answer:

Company 1: Possible

Company 3: Impossible

Company 3: Possible

Step-by-step explanation:

The six sigma levels are from 1 to 6 where 1 represents lowest quality level and 6 represents highest quality level

To find out sigma level first we have to find out DPU and DMPU

Where DPU is no. of defects divided by no. of units

And DMPU is DPU multiplied by 1 million

Company 1:

DPU = 3.4/980,000 = 0.0000030612

DMPU = 0.0000030612*1,000,000 = 3.06

Company 2:

DPU = 4/1,115,783 = 0.000003584

DMPU = 0.000003584*1,000,000 = 3.58

Company 3:

DPU = 18/5,999,521 = 0.00000300

DMPU = 0.00000300*1,000,000 = 3.0

According to six sigma tables, for six-sigma level, DMPU must be equal or less than 3.4. As you can see only company 1 and 3 has DMPU less than 3.4 therefore, it is possible for company 1 and company 3 to meet six-sigma level but impossible for company 2.

The probability

Verdich [7]

Probability of distinct 3-digits is 1/6.

Probability of both the first digit and the last digit are even numbers is 1/5.

Step-by-step explanation:

Given set of numbers {1,2,3,5,8,9} = 6

Total number of 3-digits can be formed = 6 $\times$ 5 $\times$ 4 = 120.

Probability of the three-digit numbers with distinct digits :

The number of 3-digit numbers with distinct digits = (6 $\times$ 5 $\times$ 4) / (3 $\times$ 2 $\times$ 1) = 20.

P(distinct 3-digits) = no. of distinct 3-digits / Total no.of 3-digits

⇒ 20/120

⇒ 1/6

Probability that both the first digit and the last digit of the three-digit number are even numbers :

The even numbers in the set are 2 and 8 = 2 possibilities.

The number of 3-digits with 1st and 3rd digit are even = (2 $\times$ 6 $\times$ 2) = 24.

P(1st and 3rd digits even)= no. of 1st and 3rd digit even/Total no. of 3-digits.

⇒ 24/120

⇒ 1/5
