Suppose a variable has population mean =39.45 and standard deviation =2.67 . Determine the standard error (SE) of the sampling distribution of the mean of a simple random sample of size =12 . Give your answer precise to two decimal places. SE = ?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
