Answer: to minimize the effects of variables other than the independent variable (i.e. confounding variables)
Step-by-step explanation:
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
Answer:
A. 13, 10, 16
Step-by-step explanation:
If three sides of triangle have measures a, b and c, then
Check all options:
A. a=13, b=10, c=16
Thus,
This option is true
B. a=1, b=2, c=3
Then
but 
must be greater than c, so
this option is false
C. a=5.2, b=11, c=4.9
Then
but 
must be greater than b, so
this option is false
D. a=208, b=9, c=219
Then
but must be greater than c, so
this option is false
Answer:20 gallons
Step-by-step explanation:
Answer:
X= -7
Step-by-step explanation:
Hope this helped
so, start floor = x
x + 7 - 9 - 4 + 8 - 2 = 14
x = 14
the elevator started on the 14th floor.
to verify: 14 + 7 = 21 - 9 = 12 - 4 = 8 + 8 = 16 - 2 = 14
