Answer:
2/3 or 0.667
Step-by-step explanation:
Since the bus arrival time is distributed uniformly in the interval from 10:00 and 10:30, 30 minutes. The probability that you will have to wait more than 10 minutes is 1 minus the probability you will have to wait 10 minutes or less. And since it's a distribution uniform, that probability is 10/30 = 1/3. So in the end, the probability that you will have to wait for more than 10 minutes is 1 - 1/3 = 2/3 or 0.667

Answer:
3x+2x=95
5x=95
X=19
Step-by-step explanation:
it may help you to understand
In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.
Answer: D -9
