Answer:
1. Distributive Property
2. Addition Property of Equality
3. Multiplicative Property of Equality
Step-by-step explanation:
1. The 3 is multiplied by each number in the parenthesis
3*10=30
3*2=6
So 3*(10-2x)=30-6x
2. The 30 is subtracted from both sides
30-6x-30 = -6x
6-30 = -24
30-6x-30=6-30
So -6x=-24
3. The -6 is divided from both sides
-6x/-6 = x
-24/-6 = 4
-6x/-6 = -24/-6
So x=4

Answer:
The margin of error for the confidence interval is of 0.08 = 8%.
Step-by-step explanation:
A confidence interval has two bounds, an upper bound and a lower bound. The margin of error is half the subtraction between these two bounds.
In this question:
Lower bound: 0.5
Upper bound: 0.66
Margin of error: (0.66 - 0.5)/2 = 0.16/2 = 0.08
The margin of error for the confidence interval is of 0.08 = 8%.
