Let T be the time taken in minutes to see a doctor. The surgery stipulates that no one will have to wait longer than 35 minutes. The probability density function is
given by
f(t)= t/450 ,0≤t≤35
Determine
a) The mean waiting time µ
b) The standard deviation σ
c) The probability that you will see a doctor within 15 minutes.

answer: the equation matches the regression

step-by-step explanation:

where did you get them? if you picked from the grass, is is probably poisonous.

step-by-step explanation:
