Compare standard deviations

place data sets in order from the smallest standard deviation to the largest standard deviation.

a = {9, 10, 11, 7, 13}

b = {7, 10, 11, 10, 12}

c = {10, 10, 10, 10, 10}

d = {1, 1, 10, 19, 19}

e = {1, 5, 6, 19, 19}

Step-by-step explanation:

It is convenient to let a graphing calculator or spreadsheet compute the standard deviations for you. (Some will compute sample standard deviation; some will compute population standard deviation. It makes no difference to the ordering, as long as the same computation is used for all data sets.)

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
