Answer:
Step-by-step explanation:
The only graph shown in the question doesn't have amplitude 1/2. look for a graph of a periodic wave function that has maximum y-value 1/2 (0.5) and minimum y-value 1/2 (0.5), or if it is not oscillating around the x-axis, verifies that the distance between minimum y-value and maximum y-value is "1" (one). This is because the amplitude is half of the peak-to-peak distance.
Look at the attached image as example.
Basically you multiply the probabilities
So 92/100 * 92/100 = 0.8464 so around 84-85%
Answer:
y = 120°
Step-by-step explanation:
y = 120° because opposite angles of two intersecting lines are equal
