Answer:
The correct option is D.
Step-by-step explanation:
Given the figure in which UV=XW, UX=VW and ∠UXW=∠UVW.
We have to tell why UW=UW and ∠UVW=∠WXU.
As the reflexive property of equality states that a value is equal to itself.
Hence, in quadrilateral UVWX,
UW is equal to UW by reflexive property
∠UVW=∠WXU as given
hence, UW=UW and ∠UVW=∠WXU by reflexive property and given in diagram.
The correct option is d)

Answer:
Variance, Range, Standard deviation, Inter-quartile range
Step-by-step explanation:
The most commonly used measure of variability in a data set include;
Variance and standard deviation - measures the variability of a data set about a fixed location, the mean. Variance is the square of the standard deviation.
Range - this is the difference between the largest and the smallest values in a data set.
Inter-quartile range is simply the difference between the third and the first quartile where the second quartile is the median.
Other measures include;
Downside semi-variance
