Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 140 cards,
hjlf

Answer:

a) 0.9644 or 96.44%

b) 0.5429 or 54.29%

Step-by-step explanation:

a) The probability that at least 1 defective card is in the sample P(A) = 1 - probability that no defective card is in the sample P(N)

P(A) = 1 - P(N) .....1

Given;

Total number of cards = 140

Number selected = 20

Total number of defective cards = 20

Total number of non defective cards = 140-20 = 120

P(N) = Number of possible selections of 20 non defective cards ÷ Number of possible selections of 20 cards from all the cards.

P(N) = 120C20/140C20 = 0.0356

From equation 1

P(A) = 1 - 0.0356

P(A) = 0.9644 or 96.44%

b) Using the same method as a) above

P(A) = 1 - P(N) .....1

Given;

Total number of cards = 140

Number selected = 20

Total number of defective cards = 5

Total number of non defective cards = 140-5 = 135

P(N) = 135C20/140C20 = 0.457

From equation 1

P(A) = 1 - 0.4571

P(A) = 0.5429 or 54.29%

Marianna [84]

Answer:

$45

Step-by-step explanation:

We are given the following information;

  • Money invested (Principal) is $300
  • Rate of interest is 5% per annum
  • Time the money is invested is 3 years

We need to determine the amount of interest the money will earn after three years.

  • Simple interest is calculated by the formula;
  • Simple interest =(PRT) ÷ 100, Where P is the principal amount, R is the rate of interest and T is the time.

Therefore, in this case;

Simple interest = ($300 × 5 × 3) ÷ 100

                         = $45

Thus, the money invested earned a simple interest of $45

Juliette [100K]

From year 1 to year 2, Company 1 added 6 employees (went from 6 to 12).

From year 1 to year 2, Company 2 multiplied the number of employees by 6 (went from 6 to 36).

The appropriate description is the last one ...

... company 2 because it is multiplying its number of employees by six each year while company 1 is adding 6 employees each year

_____

Multiplying by 6 each year causes the numbers to increase much faster (as you can tell by looking at the tables). Since the investment choice depends on larger numbers of employees, <em>Company 2</em> is the better choice.
