Answer:
Step-by-step explanation:
Given piecewise function is,
f(x) = -5x + 2 If x < 2
2x - 2 If x ≥ 2
For f(x) = -5x + 2 If x < 2,
Graph of this piece will be a straight line with slope = -5 and y-intercept = 2
For f(x) = 2x - 2 If x ≥ 2,
Similarly, Graph of the second piece of the function will be a straight line with slope = 2 and y-intercept = -2.
By using the graphing tool we can draw the graph of the piecewise function given.
Answer:
A. The coefficient of variation is best used when comparing two data sets that use the same units of measure.
Step-by-step explanation:
The coefficient of variation (CV), is simply the standard deviation (itself a measure of variance or variation) relative to the mean of a distribution.
The coefficient of variation expresses a random variable’s variability in percentage terms. Therefore it is possible, through the coefficient of variation, to compare the variability of data across different samples, especially if the random variables are recorded in different units of measurement (such as cm, kg and minutes).
A coefficient of variation is always interpreted as a percentage. <u>Mathematical representation is:</u>

The coefficient of variation is best used when comparing two data sets that use the same units of measure.
Hence, the option (A) is the correct option.
Greater than means it can only be greater than the value give for example x is greater than 10, x can only be a number greater than 10. Greater than or equal to is similar because the answer can be greater than the value given or equal to it. For example x is greater than 10, x could be equal to 10 or any value greater than it.
