Your answer is true so yeah
Answer:
.2121/1000
42
Step-by-step explanation:
Answer: Period: 4. Amplitude: 3
Step-by-step explanation: The period is how long it takes for one cycle of the function (one up and down). In this graph, one cycle ends at 4.
The amplitude is how far away the extremes of the graph are from the midline. This graph is a total of 6 units tall, making the amplitude 3. (I usually find total graph height and divide by 2.)
Make it a fraction
7/25 * 4/4 = 28/100
0.28 = 28 percent
There is a 28 percent chance the next marble will be red
