Standard deviation II. Consider these six data values: 10, 16, 18, 20, 22, 28.
a) Find the mean and standard deviation by hand.
b) Now look at these data values: 110, 116, 118, 120,
122, 128. Without doing any calculations, explain
why the standard deviation will be the same even
though the mean is obviously different.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
