Answer:
μ = 0.169
ME = 0.051
Step-by-step explanation:
The confidence interval is:
CI = μ ± ME
So the mean is the middle of the confidence interval, and the margin of error is half the difference.
μ = (0.118 + 0.220) / 2 = 0.169
ME = (0.220 − 0.118) / 2 = 0.051
Answer:
x = 11/42
Step-by-step explanation:
2x + 3 = 44x - 8
44x - 2x = 3 + 8
42x = 11
x = 11/42
x = 0.262
