From the given data set, the get the IQR we rearrange the set in ascending order first.
11,12,14,14,16,16.5,18,18,20
the first quartile =14
The upper quartile=18
then
IQR=Q1-Q3
=18-14=4

d is correct answer as i think.
Answer:
Area = 154 m²
Step-by-step explanation:
i pressume base = 14 m
height = 22 m
Area of a triangle = 1/2 * base * height
Area = 1/2 * 14 * 22
Area = 154 m²
Answer:
C) Horizontal compression
Step-by-step explanation:
Since, if y = f(x) is a function,
Then y = a f(x) gives a vertical stretch if a > 1 and gives a vertical compression if 0 < a < 1.
Also, y = f(bx) gives a horizontal stretch when 0 < b < 1 and gives a horizontal compression if b > 1.
Here,
The given parent function is,
f(x) = 2x
And, 3 > 1
Thus, by the above statements,
f(3x) will give a horizontal compression.
Hence, Option C is correct.
