Answer:
The sample size should be approximately 151.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 100
Population standard deviation, σ = 15
We have to evaluate the sample size, n.
Alpha, α = 0.10
Confidence interval:
Putting the values, we get,
Thus, the sample size should be approximately 151.
Answer:
8 1/6
Step-by-step explanation:
5 + 3/4 + 2 +5/12
5 + 2 = 7
3/4 + 5/12
9/12 + 5/12 = 14/12
14/12 = 7/6
7/6 = 1 1/6
7 + 1 +1/6 = 8 1/6
Hope this helped! :)
Answer:
x=13
Step-by-step explanation:
3(x-2)-3=30
3x-6-3=30
3x-9=30
3x=30+9
3x=39
x=39/3
x=13
Answer:
The answer is y squared over 12 minus x squared over 24 equals 1
Step-by-step explanation:
16 because when the line is on the x-axis, it is on zero
