Answer:
Systems of equations can be classified by the number of solutions. , . , . If a consistent system has an infinite number of solutions, it is dependent.
1. x is indefine
2. b= 16/19
3. z= -11
4. k= 23/20
5. x= 0
Answer: 4/663
Step-by-step explanation:
There are 4 6s and 4 7s, so the probability of getting a 6 on the first draw is 4/52 or 1/13. After the first draw there are 51 cards remaining (given your no replacement assumption), and there are 4 7s, so the probability of getting a 7 is 4/51.
The overall probability is
1/13 x 4/51 = 4 / 663
