you tell us, what would you end up multiplying 63.78 there, to get the 4 1/5% of it?
I don’t understand where is the equation
<span>To find the confidence interval, add and subtract the margin of error from the mean.
With mean 18.7 and margin of error 5.9, you have 95% confidence the answer is between 12.8 and 24.6.</span>
Answer:
26
Step-by-step explanation:
(3-51)-(7-81)
3-51=-48
7-81=-74
-48--74=26
I'll do it step by step:
3(x+2(3))=7(3)-9
3(x+6)=21-9
3x+18=12
I don't know what x is, so I think that's as much as I can do.
