Answer:
3 packs
Step-by-step explanation:
1 pack = $3
To see how many she could buy divide the money she has by how much each pack costs
9/3 = 3
$3 for each pack is the same as
3+3+3 = 6+3 = 9
Answer:
The provided statement is True.
Step-by-step explanation:
Holding a variable constant implies that there are no kind of relationship between the variables and the treatments.
Holding a participant variable constant has the double advantage:
(1) preventing the variable from becoming a confounding variable
(2) reducing variance within groups.
A confounding variable effects both the dependent and the independent variable remarking a relationship between the two.
Variation within group implies the difference caused by the individual values of each group.
Thus, the provided statement is True.
Step-by-step explanation:
a)as a fraction 21/60 after we simplify its
= 7/20
as a decimal 21÷60
=0.35
in percentage; 0.35×100
=35%
b)0.18 as fraction 18/100
=9/50
ratio; 9:50
percentage:9/50×100%
=18%
c)82%as a fraction 82/100
=41/50
in ratio; 41:50
as a decimal: 82/100
0.82
Answer:
Step-by-step explanation:
12
Step-by-step explanation:
Quotient rule,
Do this,
a^(n-3)=a^9
Since the exponents have to be the same, this turned into a simple one step equation:
n-3=9
+3 +3
**n = 12, so the final answer is 12.
