Yuri [45]

Answer:

B. Yes, they both mean the same thing. They can also both be represented by the expression y - 6.

Step-by-step explanation:

Given

Phrase 1: 6 less a number y

Phrase 2: 6 less than a number y

<em>Mathematically,</em>

Phrase 1 can be represented as follows;

y - 6

<em>Mathematically,</em>

Phrase 2 can be represented as follows;

y - 6

<em>Since the representation  of both phrases are the same, then option B answers the question.</em>

Acceptance Sampling Random sampling from a large lot of manufactured items yields a number of defective items X with an approxim
AfilCa [17]

Answer:

Step-by-step explanation

Let β = np, n= 5 and p= 0, 0.1, 0.3, 0.5, 0.9 and 1

x > a, a= 0

The probability of an item inspected, P(x) = β∧x*e∧-β/x!

a) For x= 1: β = 5 X 0 = 0

P(x=1) = 0

For x = 2: β = 5 X 0.1 = 0.5

P(x=2) = 0.5²*e∧-0.5/2!

For x = 3: β = 5 X 0.3 = 1.5

P(x=3) = 1.5³*e∧-1.5/3!

For x =4: β = 5 X 0.5 = 2.5

P(x=4) = 2.5∧4*e∧-2.5/4!

For x = 5: β = 5 X 0.9 = 4.5

P(x=5) = 4.5∧5*e∧-4.5/5!

For x= 6: β = 5 X 1 = 5

P(x= 6) = 5∧6*e∧-5/6!

b) For plan1, x = 1: β + 10 X 0.1 = 1

P(x=1) = e∧-1/1! = 1/e = 1/2.718 = 0.368

For plan2, x=20: β = 100 X 0.1 = 10

P(x=20) = 10∧20*e∧-10/20!

Plan 2 is preferable because the probability of success is very small and the number of trial is comparatively large, hence, the poisson distribution will be suitable probability model.

d) Plan 1 is prefered instead, because the probability of success is larger and more profit is made.

e) Plen 2 is prefered, because it will be cheaper to afford.
