Step-by-step explanation:
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.

Step-by-step explanation:
I just finished this homework so
u have
-2 -8 -18 -32 -50
-2 to -8=-6
-8 to -18=-10
-18 to -32=-14
-32 to -50=-18 now the gaps are going by 4 so it will be n^2-4
As you know a square has all of its sides equal and has four sides.To find the area,you have to know what the height and the width is.Well,we already know from the problem that one side is 58 in and as i said before all sides of a square are equal length.So the height and width would both be 58 in.Now we have to multiply the height and the width.58*58=3364.So, the area of the square is 3364 in.
