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 x2 – 12x + 59 = 0 for x.

mr_godi [17]

59 is a tough bird to deal with; its only factors are 1 and 59.

Thus, forget about factoring. Instead, use the quadratic formula, or solve the equation by completing the square.

Please note: x2 is ambiguous. Please write x^2 to indicate "the square of 2."

Here you have 1x^2 - 12x + 59 = 0, for which a=1, b=-12 and c=59.

Use the quadratic formula: x=[-b plus or minus sqrt(b^2-4ac)] / (2a)

to find the two roots. Notice that the "discriminant" b^2 - 4ac will be negative, meaning that your two roots will be "complex."

Mikayla is training for a half-marathon. At the beginning of her training, she is able to run 2 miles without stopping. Her goal

ivanzaharov [21]

Alright, lets get started.

At the beginning of her training, she is able to run 2 miles without stopping means 2 will be in the addition when we will write the equation for her running miles.

Her goal is to increase her distance by three quarters of a mile each week.

Means in first week, she will add the distance = $\frac{3}{4}$ miles

Suppose she runs x weeks, so shee will add distance = $\frac{3}{4}x$

So, suppose she runs total number of miles = d, then

$d = 2 + \frac{3}{4}x$

Where d is total numer of miles she runs

x is number of weeks : Answer

Hope it will help :)

If a radius of a sphere is divided by 2, will the surface area be divided by 2?

olganol [36]

If r is the radius of a sphere its surface area = 4(pi)r^2.

If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.

So the surface area becomes 4-fold or the increase in surface area is 300%.
