From standard normal distribution tables, obtain
p(z=0.95) = 0.8289
p(z = -2.14) = 0.0162
Therefore
p(-2.14 < z < 0.95) = 0.8289 - 0.0162 = 0.8127
Answer: a. 0.8127
Answer:
x=45°
Step-by-step explanation:
The 160° plus the unlabeled angle to the left of it are supplementary, meaning when added they equal 180°. The unlabeled angle will therefore be 20°. The angle across from the 20° will also be 20°. 115° + 20° = 135°. Now all that is left on the top half is x.
180° - 135° = 45°
