The probability is 0.1458.
The probability is given by:
No, it is not a solution.
Let's plug 5 into the equation where p is.
10(5) - 2 > 97
50 - 2 > 97
48 > 97
This is false, 48 is less than 97.
T=time
d=st
r=train speed
p=plane speed
<span>160=rt
</span><span>720=pt
speed of plan is 20kmph less than 5 times speed of train
p=5r-20
we notice that 160 times 4.5=720
times first equaton by 4.5
720=4.5rt
720=pt
set equal
4.5rt=pt
divide both sides by t
4.5r=p
sub </span><span>p=5r-20 for p
4.5r=5r-20
minus 4.5r from both sides
0=0.5r-20
add 20 to both sides
20=0.5r
times 2 both sides
40=r
sub back</span><span>
p=5r-20
p=5(40)-20
p=200-20
p=180
plane is 180kmph
train is 40kmph

Answer:
130
Step-by-step explanation:
Assuming everyone handshakes at the meeting. There will be 130 handshakes in total.
It takes 2 people to handshake, and thus to find the number of handshakes we need to do 260/2=130
130 total handshakes
Hope this helps ^^
