L = -4,4
E = -2, -3
N = 2,1
I = 4,3
E = 1,3
Answer:
±4
Step-by-step explanation:
The margin of error in a confidence interval is half the range:
(84 - 76) / 2 = 4
So the margin of error is ±4.
2√20 and 4*5^1/2. Explanation Below:
---
When we simplify 2√20, we get 4√5, and 5^1/2 is √5. Therefore, 4*5^1/2 is 4√5.

√ (1/144) = 1/12
Because √1 = 1 ; √144 = 12
⇒ C
