How many sample points are in the sample space when a coin is flipped 4 times and each time the result (heads or tails) is recorded?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°
