Answer:
or 
Step-by-step explanation:
we know that
The surface area of a cube is equal to

where
x is the length side of a cube
In this problem we have

substitute in the formula and solve for x


square root both sides

H is the correct choice.
The diagram means that parallelograms come in two kinds: rectangles and rhombuses.
So,
.. all rhombuses are parallelograms
.. all rectangles are parallelograms
.. no rectangles are rhombuses
This diagram only recognizes parallelograms that are rectangles and rhombuses. There are also other kinds of parallelograms, but those are not shown here.
Answer;
36x+27y+6
Step-by-step explanation:
This is an example of the distributive property. In order to find the expanded form of this expression, 9 must be multiplied by each numeral within the perenticies, also making sure to include the variables if essential.
Its 10 because 10 times 20 will be like a thousand
Answer:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n=234 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The Confidence level is is 0.95 or 95%, the significance is
and
, the critical value for this case would be
And replacing we got:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
