Answer:
The margin of error associated with this confidence interval is 20
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. The interval is symmetric, which means that the margin of error is the difference between these two bounds(upper - lower), divided by 2.
In this problem, we have that:
Lower bound: 520
Upper bound: 560
Determine the margin of error associated with this confidence interval.
(560 - 520)/2 = 20
The margin of error associated with this confidence interval is 20
Answer:
<u>405</u>
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- a₂ = -3a₁ = -3(5) = -15
- a₃ = -3a₂ = -3(-15) = 45
- a₄ = -3a₃ = -3(45) = -135
- a₅ = -3a₄ = -3(-135) = <u>405</u>
