Answer:
x < -11 or x ∈ (-∞, -11)
Step-by-step explanation:
4x + 6 < 3x - 5
<=> 4x - 3x < -5 - 6
<=> x < -11
Answer:
y = -2x+4
Step-by-step explanation:
the equation of the line there is: y = -2x+8
The parallel line to this one should have the same slope as the first one(-2x)
Parallel lines always have the same slopes
The confidence interval can be calculated from the margin of error, and vice versa,
The margin of error of the confidence interval is 2.156
The confidence interval is given as:

The formula of confidence interval is:

Where E represents the margin of error.
So, by comparison:

Multiply

Hence, the margin of error of the confidence interval is 2.156
