Answer:
50
Step-by-step explanation:
you break the number up into pieces that fit each problem
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50

A=8. B=4 C=4 D=5. That’s the answer
Answer:
x = (8+y)/3
Step-by-step explanation:
3x-y=8
Add y to each side
3x-y+y=8+y
3x = 8+y
Divide each side by 3
3x/3 = (8+y)/3
x = (8+y)/3
