Answer:

False, they have the same standard deviation

Step-by-step explanation:

Standard deviation is the distance each data value is from the mean.

While the mean of each data set will be different, the distance each data value is from this mean will be the same.  This is because each set goes sequentially from 1 to 12, or from 101 to 112.  The average distance from the mean will have to be the same.

To verify, using a graphing calculator, the standard deviation of the first set is 3.45.  The standard deviation of the second set is also 3.45.

Find the next item in the sequence. 15, 30, 45, 60, ...
amid [387]

The rate of change is 15. We know this because 30 - 15 = 15, 45 - 30 = 15, and 60 - 45 = 15.

The next item in the sequence would be 75, since 60 + 15 = 75.

Step-by-step explanation:

4x^2=16x     28x=28x     36=36      16x+28x-36   16+28=44-36=8x

125x^6= 30517578125x    27y^15= 2.9543127e+21                             30517578125x-2.9543127e+21= 2.9543127e+21xy

4-7=3+x=3x    5-8=3+x=3x   3x * 3x= 9x

Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease.
Rainbow [258]

Answer:

Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.

Explanation:

20 x 20 = 40 = 100%

40 / 20 = 50%
