Answer:
The standard deviation of X is 0.7
Step-by-step explanation:
We are given the following distribution:
x: 0 1 2 3
P(x): 0.3 0.5 0.2 0.4
We have to find the standard deviation of X.
Formula:

Thus, the standard deviation of X is 0.7
5 and three tenths translates to 5.3 and 2 and five tenths translates to 2.5... 5.3 - 2.5 = 2.8
2.8 translates to 2 and 8 tenths which can be simplified to...
2 and 4 fifths

Step-by-step explanation:
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
<h3>Midline, Amplitude and Period</h3>
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
