E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.

You add 127 and 68 to get 195 then you subtract 237 to get 47.
Answer:
x1= -6 x2=6
Step-by-step explanation:
x^2-10 = 26
x^2 = 26 +10
x^2 = 36
x = sqrt(36)
x = -6 or x = 6 because both 6 and -6 squared are equal to 36
Answer:
The answer is A and E
x2+(y−3)2=36
x^{2}+(y+8)^{2}=36x2+(y+8)2=36
Answer:
I believe its B, But I am unsure since I haven't done geometry in a couple years.
