We know that the initial temperature is -3 then it rises to 8 and drops by 6 degrees then you just need to subtract six from 8 
Answer:
3/5
Step-by-step explanation:
12/20
(divide both by 2)
12/2= 6
20/2=10
6/10
(divide by both by 2)
6/2= 3
10/2= 5
3/5
450/25=18; 18x10=180. therefore the answer is B: 180 inches
The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
