There are lots of them I know but I will only give you a few of them.
14/30 56/120
21/45 63/135
28/60 70/150
35/75 77/165
42/90 84/180
49/105 91/195
Since the standard deviation is not given, we assume the process is a Poisson process, with mean 12000 miles.
From Poisson distribution tables, we see that with a value of lambda(mean)=12000, the lower tail probability for x=12140 miles is 0.9000105, which means that the 90 percentile is 12140 miles.
The lower-tail probability of 9000 miles is 6.2*10^(-181) which is essentially zero.
NOTE: if the problem were modelled with a normal distribution, the probabilities would be completely different.
She started out with 335, and spent 15 each week, she now has 155 dollars- that will be our equal sign.
let m= money she spent each week.
335- 15m= 155
Subtract 335 from 155.
-15m= -180
Divide -15 into both sides.
m= 12
