A chip company has two manufacturing plants. Plant A produces 40% of the chips and Plant B produces 60% of the chips produced by

erik [133]

Answer:

P(A/D) = 0.5714

Step-by-step explanation:

Let's call A the event that a chip is produced by Plant A, B the event that a chip is produced by Plant B and D the event that the chip is defective

So, the likelihood or probability P(A/D) that a chip came from plant A given that the chip is defective is calculated as:

P(A/D) = P(A∩D)/P(D)

Where P(D) = P(A∩D) + P(B∩D)

Then, the probability P(A∩D) that a chip is produced by plant A and it is defective is calculated as:

P(A∩D) = 0.4*0.02 = 0.008

Because, Plant A produces 40% of the chips and 2% of the chips produced by plant A are defective.

At the same way, the probability P(B∩D) that a chip is produced by plant B and it is defective is calculated as:

P(B∩D) = 0.6*0.01 = 0.006

So, P(D) and P(A/D) are equal to:

P(D) = 0.008 + 0.006 = 0.014

P(A/D) = 0.008/0.014 = 0.5714

it means that if a randomly chosen chip produced by the company is defective, the likelihood that the chip came from plant A is 0.5714

How do I solve this

xz_007 [3.2K]

Let, the number of books I can buy = x

Selling price for 1 book = $5.99

So, selling price for x books = $(5.99x)

Given 7.5% is the sales tax.

To find sales tax we have to find 7.5% of $(5.99x)

7.5% of $(5.99x) = (5.99x) × 7.5/100 = (5.99x) × (0.075) = (0.44925x)

So the amount of sales tax = $(0.44925x)

The total cost for buying books including sales tax

= $(5.99x) + $(0.44925x)

=$(6.43925x)

Now given, the shipping cost is 10% of the price.

So to find the shipping cost we have to find 10% of $(6.43925x)

10% of $(6.43925x) = (6.43925x) × (10/100) = (6.43925x) ×(0.1) = (0.643925x)

Shipping charge = $(0.643925x)

So the total cost including shipping charge

= $(6.43925x) + $(0.643925x)

= $(7.083175x)

Now given, there is $50 to spend on books. So to find the number of books we can equate them.

7.083175x = 50

To get x, we have to divide both sides by 7.083175

(7.083175x)/7.083175 = 50/7.083175

x = 7.05898

As we are finding the number of books, so we will take the nearest whole number. Here the nearest whole number is 7.

So the required answer is 7 books.

12 gallons of gas to travel 144 miles. Six gallons in the tank how much more will she need to travel 240

ira [324]

Solution:
Here:
On 12 gallons of gas 144 miles is travelled.
So, for 1 mile :
$\frac{12}{144} \: gallons \: of \: gas$
$= \frac{1}{12} \: gallons \: of \: gas$
is required.
Now,
for 240 miles:
$\frac{1}{12} \times 240$
$= 20 \: gallons \: of \: gas$
is required.
But, according to question, the tank only contains 6 gallons of gas. So, see needs more (20 - 6) gallons of gas [i.e. 14 gallons of gas].
