- 1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
- 2. ⇒ z = - (2.5 - 0.72)
- 3. ⇒ z = - 1.78
The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
A suitable statistics calculator gives the probability that 6 or more show up as being about ...

Hello,
For this problem, we will use cosine which is adjacent over hypotenuse. They want you to solve for the hypotenuse.
cos(56.76) = 56.76/x (multiply both sides by x)
x cos(56.76) = 56.76 (divide both sides by cos(56.76))
x = 103.548816..
x = 103.5
Your final answer approximately x = 103.5.
