Two stores sell a certain product. Store A has 45% of the sales, 3% of which are of defective items, and store B has 55% of the

Mumz [18]

Answer:

$Probability = 0.0355$

Step-by-step explanation:

Given

Stot A:

$Sales = 45\%$

Defective = 3%

Store B

$Sales = 55\%$

Defective = 4%

Required

Determine the probability a product received is defective.

First, we calculate the probability that the defective product is from store A

$Probability = P(Sales) * P(Defective)$

$P_A = 45\% * 3\%$

Convert to decimals

$P_A= 0.45 * 0.03$

$P_A= 0.0135$

Next, we calculate the probability that the defective product is from store B

$P_B= 55\% * 4\%$

$P_B= 0.55 * 0.04$

$P_B= 0.022$

The product may come from either stores.

So, the probability of having a defective product is:

$Probability = P_A + P_B$

$Probability = 0.0135 + 0.022$

$Probability = 0.0355$

Solve for x, 3ax+2b/c =4a

AfilCa [17]

Answer:

ANSWER = X = 4ac - 2b / 3ac

Step-by-step explanation:

Let's solve for x.

3a x + 2b / c = 4a

Step 1: Multiply both sides by c.

3acx + 2b = 4ac

Step 2: Add -2b to both sides.

3acx + 2b + −2b = 4ac + −2b

3acx = 4ac − 2b

Step 3: Divide both sides by 3ac.

3acx / 3ac = 4ac − 2b / 3ac

Answer = x = 4ac − 2b / 3ac

Let f(x) = 5x + x2 and g(x) = 3x2 - 4x. Find f(x) * g(x)

gavmur [86]

Step-by-step explanation:

f(x) × g(x)

= (x2 + 5x )× (3x2 -4x )

=3x4 + 15x3 - 4x3 -20x2

3x^4 + 11 x3 - 20x2
