mean
standard deviation
= number of seats occupied
D = 75.8
8. = 14.8
y = ticket revenue (dollars)
y = 696
S = 1776
T = 0.81

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

is means division by fractions

step-by-step explanation:

i believe the answer is the polygon, heptagon.
