Answer:
1/7
Step-by-step explanation:
The word "compute" has 7 letters, 3 of which are vowels.
The probability that the first letter is a vowel is 3/7.
There's no replacement, so there are 6 letters left, 2 of which are vowels.
The probability that the second letter is a vowel is 2/6.
The probability of 2 vowels is therefore:
P = (3/7) (2/6)
P = 1/7
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
The correct answer is D. No because the permutations rule would be used to determine the total number of combinations.
Explanation:
The difference between a combination and a permutation is that in permutations the order is considered. This applies to the numbers in a lock because these need to be in order. Therefore, to analyze the permutations in a lock, the rule for permutations should be used. This includes the general formula P (n,r) =
; in this, n is the number of objects and r refers to the objects used in a permutation. Thus, the term "combination" is inappropriate because this is a permutation, and the permutation rule should be used.
Since there are no measurements, a Clydesdale is a Shetland pony and American saddlebred.
The answer is gonna be x+3/x-2
