Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
is the sample mean and ME is the margin of error .
Given : The sample mean : 
Margin of error : 
Then , the range of values (confidence interval) likely to contain the true value of the population parameter will be :-
Hence, the range of values likely to contain the true value of the population parameter =
It’s not the same because if you simplify them there going to end up looking different (the answers) And they get a whole different do you denominator a numerator
To sum up, we only have the length of one side.
We need to find the width of the same side. -
20.5 x 20.5 = 420.25
To get the surface area, we multiply by six.
<u>Why?</u> There are six sides on a cube.
420.25 x 6 = 2521.5
Answer: 2521.5 cm
2/18 reduced = 1/9 that's my answer
