To find out the cyclist's average speed you simply have to divide 50.0km
by 2.5 to find the answer. Therefore the cyclist's average speed is
20.0 km an hour.
A + s = 444
s = 2a
a + 2a = 444
3a = 444
a = 444/3
a = 148 <== adults
s = 2a
s = 2(148)
s = 296 ...students
It could be 7:4 or, 28:16.
Title:
<h2>The desirable probability is

.</h2>
Step-by-step explanation:
There is a 20% chance of winning a bid.
Hence, the chance of losing a bid is (100 - 20) = 80%.
It is given that i have win in X bids out of total 6 bids.
I have loosed in (6 - X) bids.
Again, from 6 bids we can chose X bids in
ways.
Hence, the required probability is
