1 Simplify \frac{4}{15}x
15
4
x to \frac{4x}{15}
15
4x \frac{4x}{15}=1.44
4x =1.44
2 Multiply both sides by 1515.
4x=1.44\times 15
4x=1.44×15
3 Simplify 1.44\times 151.44×15 to 21.621.6.
4x=21.6
4x=21.6
4 Divide both sides by 44.
x=\frac{21.6}{4}
x= 4
21.65 Simplify \frac{21.6}{4} 421.6 to 5.45.4.
x=5.4
x=5.4
Answer:
Option A is right
Step-by-step explanation:
In any data set, we find that the range is the difference between maximum and minimum. The range cannot give full information about the variability of the data set.
Outliers are the ones which are either below Q1-1.5IQR or Q3+1.5IQR
Thus Inter quartile range, the difference between I quartile and III quartile gives a better idea about variability and also outlier.
Hence out of the four options given, we find that option B is the right one.
Option
A. The IQR is the best measure of variability because the distribution has an outlier.

Okay well, just by looking at the graph. It’s a negative slope and the only answer, that has a negative is the 3 one.
