Since there is no repetition allowed, there are 10 possibilities for the 1st digit, 9 for the 2nd, 8 for the 3rd, and 7 for the 4th. This gives a total of (10)(9)(8)(7) = 5040 four-digit codes.
For all odd digits to be used, there are 5 possibilities for the 1st digit (1,3,5,7,9), 4 for the 2nd, 3 for the 3rd, 2 for the 4th. This gives a total of (5)(4)(3)(2) = 120 codes that only use odd digits.
Therefore there are 5040 - 120 = 4920 codes that do not consist of all odd digits. The probability is 4920/5040 = 41/42.
Sorry for throw but I need points
4d = 24 would be the right equation. To double check you would divide both sides by 4 (the number of legs) to find the amount of dogs.
The geometric properties of the parallelogram show that each to opposite side of a parallelogram are parallel and equal in length.
Thus, for this problem:
The first two opposite sides will be 10 ft long and they are also parallel
The third side is 6 ft long
This means that the fourth side will definitely be equal to the third one and parallel to it.
The answer is : A) 6 ft
Answer:
21
Step-by-step explanation:
49 - 4 x 49 / 7 =
49 - 196 / 7 =
49 - 28 =
21
