The probability that the train will be there when Alex arrives is 0.1.
Given that the time that train arrives between 1:00 P.M to 2:00 P.M. and waits for 10 minutes. Alex arrives between 1:00 P.M to 2:00 P.M.
We are required to find the probability that the train when Alex arrives.
Probability is the likeliness of happening an event among all the events that are possible to happen.
Probability=Number of items/total number of items.
Number of combinations of timings in which the train may have arrived=60/10=6 combinations
Number of ways in which Alex arrives at the station=60.
Probability=6/60
=1/10
=0.1
Hence the probability that the train will be there when Alex arrives ie 0.1.
Question is incomplete. The following things should be included:
Timing in which train arrives is between 1:00 P.M and 2:00 P.M.The train waits for 10 minutes. Alex arrives between 1:00 P.M and 2:00 P.M.

Answer:
true
Step-by-step explanation:
4x - y = 61
2y = x
substitute x = 2y in first equaation:-
4(2y) - y = 61
7y = 61
y = 61/7
so x = 2 * 61/7 = 122/7
y = 8 5/7 and x = 17 3/7
Answer:
2x - 10
Step-by-step explanation:
'x' = amount David has
Alexis = 2x - 10
<span>Part A
</span>The variables would be x and y where as the coefficients would be 25 and 100
Part B
There are two terms in the expression, those being 25x and 100y. This is because s plus or minus sign separates terms, and in this case, we only have one plus sign.
<span>Part C
</span>The term that represents the total earnings from mowing lawns in 100y, because the prompt says that he earns $100 mowing lawns.
