Standard deviation is like the average range values are away from the mean/median. So if you remember box and whisker plots, It is 2 boxes with 2 lines coming from them. Where the boxes meet is the mean/median depending on what you are trying to find, and the edges of the boxes are the normal distribution of values, and the lines go out, and that's the standard deviation. The values outside of those lines are outliers. A way you can think about it, is if let's say I had 3 numbers: 7,8,9. Now the mean/median is 8, and for this the standard deviation is 1 because most numbers that are not the median/mean are 1 value from the median/mean. It is a way of measuring an element of range. I hope this helped.
I believe the equation should be y = -0.5sin(x-2<span>π)-2</span>
Answer:
The probability is 0.0179 or 1.79%
Step-by-step explanation:
This is a binomial probability distribution.
The probability of success is
The probability of failure is
Use the formula;
where n=6 is the number of trials and x=4 is the number of successes.
This implies that:
This simplifies to:
Figure 1 was translated using the rule (x', y') ⇒ (x -9, y + 2) to produce figure 2.
<h3>What is
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are t<em>ranslation, reflection, rotation and dilation.</em>
Translation is the movement of a point either up, down, left or right on the coordinate plane.
Figure 1 was translated 9 units left and 2 units up using the rule (x', y') ⇒ (x -9, y + 2) to produce figure 2.

Answer:
Circumference: 47.1 inches Area: 176.71 inches ²
Step-by-step explanation:
To find the circumference of a circle, you multiply the diameter(15) to pi (3.14).
To find the area of a circle, you find the radius of the circle, which is half of the diameter (7.5), square it, which equals 56.25, multiply that by pi (3.14) and there is your area. Make sure to write your answer to area in square inches.
