Answer:

x= 2/3 -1/3y or x= -1/3y + 2/3

Step-by-step explanation:

3x + y= 2 (subtract the y to get 3x by itself)

3x= 2-y (divide both sides by 3 to get x by itself)

x= 2/3 - 1/3y

zhenek [66]

Question:

If a sample of 2 hammer is selected

(a) find the probability that all in the sample are defective.

(b) find the probability that none in the sample are defective.

Answer:

a $Pr = \frac{2}{110}$

b $Pr = \frac{72}{110}$

Step-by-step explanation:

Given

$n = 11$ --- hammers

$r = 2$ --- selection

This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities

Solving (a): Probability that both selection are defective.

For two selections, the probability that all are defective is:

$Pr = P(D) * P(D)$

$Pr = \frac{2}{11} * \frac{2-1}{11-1}$

$Pr = \frac{2}{11} * \frac{1}{10}$

$Pr = \frac{2}{110}$

Solving (b): Probability that none are defective.

The probability that a selection is not defective is:

$P(D') = \frac{9}{11}$

For two selections, the probability that all are not defective is:

$Pr = P(D') * P(D')$

$Pr = \frac{9}{11} * \frac{9-1}{11-1}$

$Pr = \frac{9}{11} * \frac{8}{10}$

$Pr = \frac{72}{110}$

store announced that their $500 appliances were on sale for $475 what is the percent discount on the appliances

Aleks04 [339]

Answer:

We are given that a store announced that their $500 appliances were on sale.

The price of the appliances after discount is $475.

We are required to find the percent discount on the appliances.

To find the percent discount, we have to use the below formula:

$\frac{(Actual-discounted)}{Actual} \times 100\%$

$\frac{500-475}{500}\times 100\%$

$\frac{25}{500} \times 100\%$

$0.05 \times 100\%$

$5\%$

Therefore, the percent discount on the appliances is 5%
