Answer:
1/12
Step-by-step explanation:
1/2-[-1/4+2/3]
1/2-[-3/12+8/12]
1/2-[5/12]
1/2-5/12
6/12-5/12
1/12
Multiply exponents together if it is on another exponent
(8^2)^6= 8^12
Answer:
9/12=3/4
Step-by-step explanation:
Step 1: Find the GCF, which is 3.
Step 2: Divide 3 from the denominator and the numerator.
Then you get your answer of 3/4.
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
