Answer:
x= 8
x= -8
Step-by-step explanation:
|x+1| /3 = 3
|x+1| = 9
|x| + |1| = 9
|x| = 8
x= 8
x= -8
Answer: The answer is (C) cannot be determined.
Step-by-step explanation: Given that Jennifer and James planned to drive from home to the stadium to watch a football match on a rainy day. The distance from home to stadium is 30 miles.
Also, when they reached half the distance, i.e., they covered 15 miles, then they realised that they forgot the tickets, because of which they had to drove back to home and then again to the stadium.
Therefore, the total distance they covered = 15 + 15 + 30 =60 miles, i.e., they had to cover double the distance from home to the stadium.
Finally, it is given that the game was fantastic with final score of 21 to 20. This information has no relation to the original question which was about the distance, not score and we cannot find out score from the given information.
Thus, the correct option is (C) cannot be determined.
Answer:
Step-by-step explanation:
The probability that the man gets x out of 20 correct follows a Binomial distribution, so the probability is calculated as:
Where n is the number of identical experiments and p is the probability of success. In this case n is 20.
Additionally, if he has no ESP the probability that he predict correctly is 0.5, because he is only guessing.
Then, the probability that he gets x out of 20 correct is equal to:
Therefore the probability that he would have done at least 17 out of 20 well if he had no ESP is:
Where:
So, 
is equal to:
