A manufacturer of tablets receives its LED screens from three different suppliers, 45% from supplier B1, 30% from supplier B2, a

Shalnov [3]

Answer:

a) 0.83 = 83% probability that a LED screen will meet specifications.

b) 0.2892 = 28.92% probability that a LED screen that meets specifications was sent by the second supplier.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

45% from supplier B1, 30% from supplier B2, and the rest from supplier B3.

So 100 - (45 + 30) = 100 - 75 = 25% from supplier B3.

a) Find the probability that a LED screen will meet specifications.

95% of 45%(supplier B1)

80% of 30%(supplier B2)

65% of 25%(supplier B3). So

$p = 0.95*0.45 + 0.8*0.3 + 0.65*0.25 = 0.83$

0.83 = 83% probability that a LED screen will meet specifications.

b) Calculate the probability that a LED screen that meets specifications was sent by the second supplier.

Conditional probability.

Event A: Meets specifications.

Event B: Sent by second supplier.

0.83 = 83% probability that a LED screen will meet specifications.

This means that $P(A) = 0.83$

Meets specifications and is sent by the second supplier.

80% of 30%, so

$P(A \cap B) = 0.8*0.3 = 0.24$

Probability:

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.24}{0.83} = 0.2892$

0.2892 = 28.92% probability that a LED screen that meets specifications was sent by the second supplier.

The answer would be wx(yz) because the associative property says that you can change where the parenthesis are while keeping the same equation.
The equation is w(xy)z, but moving the parenthesis some where else will not change it, such as wx(yz).

Which option gives you more snack when spending the same amount of money?

Oksi-84 [34.3K]

Answer:

Spending the same amount of money, Cheetos gives more snacks than Doritos, since with the same money more ounces of the product will be obtained.

Step-by-step explanation:

Given that the Doritos package costs $ 4.39 and contains 11.5 ounces of product, the price of each ounce of said snack comes from the following calculation:

4.39 / 11.5 = X

0.38 = X

Therefore, each ounce of Doritos costs $ 0.38.

In turn, the Cheetos package costs $ 3.24 and contains 9.75 ounces of snacks, so its price per ounce is obtained through the following calculation:

3.24 / 9.75 = X

0.33 = X

Thus, each ounce of Cheetos costs $ 0.33.

Therefore, spending the same amount of money, Cheetos gives more snacks than Doritos, since with the same money more ounces of the product will be obtained.
