In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Quadrilateral ABCD has vertices A(-2,4), B(-3.-3), C(-5,-2), D(-5,2). Which of the following are the coordinates of A’ after a d
Gala2k [10]
<h2>Answer:</h2>

\boxed{A'(-5,10)}

<h2>Step-by-step explanation:</h2>

Dilation is when you stretch something by the same amount in two perpendicular directions. In other words, dilation changes size, not overall shape. Dilation factors greater than one makes the shape greater while dilation factors less than one makes the shape smaller. The scale factor in this problem is:

2\frac{1}{2}

Which is a mixed fraction. This can be transformed into an improper fraction as follows:

2\frac{1}{2}=2+\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}

So the scale factor is \frac{5}{2}. Since the center of dilation is the origin, we just need to multiply each vertex of the quadrilateral by the scale factor. Thus, for A we have:

A'(-2\times \frac{5}{2},4\times \frac{5}{2})=\boxed{A'(-5,10)}

Solve for x. Thanks!
Vladimir79 [104]

Answer:

x = \frac{2T}{nd} - a

Step-by-step explanation:

Multiply both sides by 2 to eliminate the fraction

2T = n(a + x)d

Since n and d are both multipliers, divide both sides by nd

\frac{2T}{nd} = a + x

Isolate x by subtracting a from both sides, hence

x = \frac{2T}{nd} - a
