There are 4! = 24 poosible permutations of the four letters. Let the letters be A, B, C and D. Two permutations will have only letter A in the correct envelope, two more permutations will have only letter B in the correct envelope, two more will have only letter C in the correct envelope and two more will have only letter D in the correct envelope. Therefore 8 out of the 24 possible permutations will have only one letter with the correct address. The required probability is 8/24 = 1/3.
Terms in Pattern B are double the corresponding terms in Pattern A
Answer:
20 - 12x = 48 answer.
Step-by-step explanation:
Multiply the whole equation by 4. Use 4 because that is the denominator of the fraction 3/4. You want to get rid of the fraction.
4(5 - 3/4 x = 12)
20 - 12x = 48
Answer:
The woman bought 2 items at $12 each.
Step-by-step explanation:
Given that a woman bought a number of items for $ 24, and she realized that if she had bought 4 more items for the same money, she would have paid $ 8 less per item, to determine how many Items did she buy the following calculation must be done:
X = 24
X + 4 = 24
24/2 = 12
24/6 = 4
12 - 4 = 8
Therefore, the woman bought 2 items.
Answer:
a) 
is greatest fraction.
b) 
is greatest fraction.
c) 
is greatest fraction.
d)
