A rectangle<span> has two </span>diagonals<span>. Each one is a line segment drawn between the opposite vertices (corners) of the </span>rectangle<span>. By using the Pythagorean Theorem, we can calculate the width. We do as follows:
c^2 = a^2 + b^2
a = sqrt( c^2 - b^2 )
a = 68.74 yards</span>
Answer:
we know that
If two figures are similar, then its corresponding sides are proportional and its corresponding angles are congruent
In this problem
Triangles XZY and VZW are similar
therefore
corresponding angles are congruent
∠XZY≅∠VZW
∠ZXY≅∠ZVW
∠XYZ≅∠VWZ
corresponding sides are proportional

Answer:
3. Standard deviation is the square root of the variance.
4. Standard deviation is useful because it has the same units as the underlying data.
Step-by-step explanation:
3. In statistics, the dispersion in a given data with respect to its mean distribution can be determined or measured by standard deviation and variance. The standard deviation of a distribution can also be determined as the square root of variance.
4. Standard deviation is measured in the same units as that of the original data. Thus it has the same units as the underlying data.
