The three major features of a well designed experiment are:
1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment
2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables

The image is really unclear but I will assume that the number of teams given = 66
and the formula is
plug in the number of teams
multiply both sides by two
subtract 132 from both sides and factor
t = 12
Answer:
11
Step-by-step explanation:
First, find how much a token costs.
4.40 ÷ 8 = .55
Then divide 6.05 by .55 to get 11.
6.5c + 9.7a = 1721.4
a = 4c
6.5c + 9.7(4c) = 1721.4
6.5c + 38.8c = 1721.4
45.3c = 1721.4
c = 1721.4 / 45.3
c = 38...so there were 38 childrens' tickets <==
and 152 adult tickets
