Six hundred paving stones were examined for cracks, and 15 were found to be cracked. The same 600 stones were then examined for discoloration, and 27 were found to be discolored. A total of 564 stones were neither cracked nor discolored. One of these 600 stones is chosen at random. What is the probability that it is both cracked and distorted?

Answer: 0.01

Step-by-step explanation:

Let the events are :

C = paving stones found to be cracked.

D = paving stones found to be discolored.

Given : Total stones : T = 600 (i)

C = 15

D= 27

C'∩D'= 564 (ii)

Since C'∩D' = (C∪D)' = T- C∪D (iii)

From (i) , (ii)and (ii) , we have

564 = 600- C∪D

⇒ C∪D=600- 564= 36

Formula : C∩D= C+D- C∪D

Put values , we get

C∩D= 15+27-36=6

Now ,

The probability that it is both cracked and distorted is 0.01.

What scale factor is applied to shape B to make shape A (A) 8 , 6 , 2 , 2

(B) 12, 9 , 3 , 3

Answer:

Scale factor of (k) =3/2 is applied here.

Step-by-step explanation:

Given:

Points:

(A) 8 , 6 , 2 , 2

(B) 12, 9 , 3 , 3

We have to find scale factor applied to shape (B).

Scale factor is the ratio of length or two numbers to which if we multiply the number result will be same.

Here B values are will be considered as numerators.

and

A values are which are denominators.

Scale factor = ratio of the numbers = numerator divided by the denominator

So,

Scale factor ,(k)=?

⇒

Reducing to the simplest number.

Divide with 4 to both the numbers.

⇒

So the scale factor applied to shape B to make it similar to shape A is 3/2.

a clothing store office very often various promotions to attract customers but wants to maintain the same amount of profit to do this the store mark up prices above retail and then advertises a deal that results in a markdown equivalent to a retail price the retail prices of a necktie is $59.99 the store offers a buy 2 get 1 free deal on neckties what is the new retail price during this promotion what is the markup and what is the markup percent on a tie during the promotion.

Since 3 neckties will be out from the store, so you need to know how much is the cost of 3 ties.

$59.99 x 3 = $179.97 and divide it by two because the costumer will only pay for 2

$179.97 / 2 = $89.99 is the new price

Mark up = 89.99 – 59.99 = $30.00

% mark up = [(89.99/59.99) -1] * 100

= 50%
