Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 110 cards,
Yakvenalex [24]

Answer:

The answers to the questions are;

(a) P(At least 1 defective)

= 0.9883.

(b) P(At least 1 defective)

= 0.6409.

Step-by-step explanation:

There are 110 cards and 20 defectives.

a) The probability of at least one defective is given by

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = 20C0 × (90C0)/(110C20) = 0.0116

1 - 0.0116 = 0.9883

b) For a set of 110 boards that has 5 defective and 105 non-defective

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = (20C0)(90C5)/(110C5) = 0.35909

1-0.35909

= 0.6409

Mala has a collection of bangles. She has 20 gold bangles and 10 silver bangles. What is the percentage of bangles of each type?
Rainbow [258]

Answer:

Percentage of gold bangles is 66.6 and of silver bangles it is 33.3

Step-by-step explanation:

Given:

Number of gold bangles Mala has = 20

Number of silver bangles she has  = 10

Total number of bangles = 20+10 = 30

We have to find the percentage of each type of bangles.

So,

Percentage of bangles  = \frac{No.\ of \ bangles\ each\ type}{Total\ no.\ of \ bangles} \times 100

  • Percentage of gold bangles.

        ⇒ \frac{20}{30} \times 100

        ⇒ \frac{20\times 100}{30}

        ⇒ \frac{2000}{30}

        ⇒ \frac{200}{3}

        ⇒ 66.6\%

  • Percentage of silver bangles.

       ⇒ \frac{10}{30}\times 100

       ⇒ 33.3\%

Percentage of gold bangles, Mala has = 66.6 and of silver bangles it is = 33.3

Joshua currently does a total of 8 pushups each day. He plans to increase the number of pushups he does each day by 2 pushups un
Maslowich

Answer:

x=12

Step-by-step explanation:

Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.

Ed's age is twice that of his brother. When you add Ed's age to his brother's age, you get 36. How old is each brother?
svlad2 [7]

The answer to your question is,

Ed is 27. His brother is 9.

How did I get this answer?

Ed's age is twice that of his brother. So of course, when you divide 36 by 2, you would get 18. They are not twins so this wouldn't be the answer. You need to divide 18 by 2 again. This makes 9. If you add 9 to 27, that makes 36. Which is their ages.
