Hello!

The mean is 12

The data has a standard deviation of 4

Look and see how far away 18 is from 12 using 4

12 + 4 = 16

16 is one deviation

16 + 4 = 20

20 is two deviation

18 is right in the middle

The answer is C. 1.5 deviations

Hope this helps!

Find the percent of change <br><br> a: 1/3 to 2/3<br><br> b: 1/3 to 1/6<br><br> please help!
Dimas [21]

Answer:

a: The percentage change from 1/3 to 2/3 is 100 %

b: The percentage change from 1/3 to 1/6 is 0 %

Step-by-step explanation:

use this formula:

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((2/3 - 1/3) / 1/3) * 100 = 100 %

_________________________________

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((1/6 - 1/3) / 1/3) * 100 = 0 %
