a) This is an exponential distribution question since it is a poisson type problem
Mean rate is 0.95 per 1000 passengers
Mean rate, 
per passenger
Probability that at least 490 passengers will have their baggage handled properly before the next mishandling occurs
:



b) Probability that the number will be fewer than 200 passengers

Amount times concentration=quantity
50(0.15)+x(1)=(50+x)(0.25)
x=amount of acid to add
so
7.5+x=12.5+0.25x
minus 0.25x both sides
7.5+0.75x=12.5
minus 7.5 both sides
0.75x=5
divide both sides by 0.75
x=6.666666666
converts to 6 and 2/3
you have to add 6 and 2/3ml of pure acid
Hello,
Let C the center of wheel.
P is the Carl's seat
A is the intercept of the horizontal line passing by A and the vertical line passing by P
In the right triangle PAC, sin 72°=AP/CP
==>

≈8.5595....
The height of Carl's seat
is 11-8.5595...=2.440491...(m)
