Chuck has a box with 7 balls in it. 3 of them are blue and 4 of them are yellow. Chuck is going to
take a ball out of the box, put the ball back and
then take a second ball out of the box. What is the
probability that Chuck chooses a blue ball and
then a yellow ball?

12/49

Step-by-step explanation:

Total number of balls - 7Blue - 3Yellow - 4

Probability of blue ball:

3/7

Probability of yellow ball:

4/7

Probability of blue and then yellow:

3/7*4/7 = 12/49

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Im pretty sure it’s is b 1.6 mi
