Suppose that the amount of time people spend in a maze at a fall festival is approximately Normally distributed; on average people spend 12 minutes in the maze, and the SD is 3 minutes. If this model is correct, compute the proportion of people that spend at most 5 minutes in the maze. Decimal form, four places.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
