Answer:
3.5 to 20.5 hours
Step-by-step explanation:
The range of the sine function is -1 to 1, so the range of H will be ...
-8.5 +12 = 3.5
to
8.5 +12 = 20.5
The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.

2=(x-2.7)/.5
(2)(.5) = x-2.7
1=x-2.7
x=3.7
-2.5=(x-2.7)/.5
(-2.5)(.5) = x-2.7
-1.25 =x-2.7
x=2.7-1.25 = 1.45
b)
95% of the students' score lie within 2 standard deviation of the mean. Therefore, the top 2.5% corresponds to a z value of 2.
The limits are (2, infinity) --- top 2.5 %</span>
2-2a+2b+2c? Really, just start with one number/variable and apply multiplication, addition, or subtraction to it as you move towards the right.
