The probability is 0.69.
We find the z-scores that correspond with each end of the range we're looking for. To find a z-score, we use the formula:
Using a z-table (http://www.z-table.com) we see that the area under the curve left of the score 350 would be 0.228. The area under the curve left of the score 400 would be 0.918. To find just the range between 350 and 400, we subtract the area left of 350 from the area left of 400; this will give us just from 350 to 400:
0.918-0.228 = 0.69.

Answer-
<em>The inverse of is </em>
<u>Solution-</u>
The given function is,
We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.
So in the inverse would be,
Taking log of both sides,
As,
Applying the same,
As,
Applying the same,
Therefore, the inverse of is
.
