Answer:
The answer is E: I, II, and III
Step-by-step explanation:
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
3. Randomization: Subjects are expected to be randomly assigned to different groups.
A. 9 3/4 hours
b. i’m not too sure :)
Answer:
see explanation
Step-by-step explanation:
The largest angle is opposite the largest side and the smallest angle is opposite the shortest side.
Δ FUN
largest angle is ∠ FUN ( opposite FN )
smallest angle is ∠ NFU ( opposite NU )
Δ GEO
largest angle is ∠ GEO ( opposite GO )
smallest angle is ∠ GOE ( opposite GE )
---------------------------------------------------------------------------
The longest side is opposite the largest angle and the shortest side is opposite the smallest angle.
∠ RTY = 180° - (70 + 55)° = 180° - 125° = 55°
Δ TRY is therefore isosceles with 2 congruent legs RT, RY
longest side is TY ( opposite 70° )
shortest sides are RT , RY ( opposite 55° )
