Answer:
are there any answer choices?
The probability that the train will be there when Alex arrives is 5/18
If Alex arrives at any time after 1.20pm the chances that train will be there is 1/3.
However if alex arrives at 1.00pm exactly there is no chance the train will be arrive there.
The probability that the train will be there increase linearly to 1/3 as alex's arrival time moves from 1.00pm to 1.20pm.
By arranging the probabilities over the first 20 minutes to get a 1/6 chance the train will be there if alex arrives between 1.00pm to 1.20pm
we get the final answer by
=1/3( 1/6 + 1/3 + 1/3)
=5/18
So, the probability that the train will be there when Alex arrives is 5/18

Answer:
c = (b+3a)/2
Step-by-step explanation:
<u>Solve for c:</u>
<u>Multiply both sides by abc:</u>
- abc/ac = 2abc/ab - 3abc/bc
- b = 2c - 3a
- b + 3a = 2c
- 2c = b + 3a
- c = (b + 3a)/2
