How to get expected value of a distribution no need to type detailed equation

I tried in Wolfram Alpha online but failure to get the expected value of a uniform distribution with min=80 max=170 in where x=95, maybe my input online is not correct which couldn’t be recognized by Wolfram Alpha, could anyone help on this? Thanks. Is it necessary to type the detailed equation? Is it possible to use defined simple function language?

Maybe this?

The expected value for a uniform distribution is the the average of the min and max. So what purpose is the statement x=95?
