Answer: To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: Addition and subtraction.

Answer:
Multiply the time per day by the number of days per week.
6/8 x 6 = (6 x 6)/8 = 36/8 = 4 1/2 hours a week.
Step-by-step explanation:
Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
Answer:
$1,104
Step-by-step explanation:
If the discount is 8%, then you would need to subtract 8% (0.08) from 1, which would be 0.92. Now multiply $1,200 by 0.92 and you'll get $1,104.
