Answer:
24
Step-by-step explanation:
Just subtract the first quartile form the third quartile.
third quartile - first quartile
32 - 8 = 24 IQR
FIRST quartile: 8
SECOND quartile: 20
THIRD quartile: 32
So the IQR is 24
Hope this helps :)

7n +6= 4n -9
7n-4n= -6 -9
3n = -15
n = -15/3
n = -5
Answer:
B
Step-by-step explanation:
The red graph is a horizontal translation of 5 units left, followed by a reflection in the x- axis, of the black graph.
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here the graph is shifted 5 units to the left, thus
f(x) → f(x + 5)
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Note the y- coordinate of the image is the negative of the original
Note that
= - y, thus
The equation of the red graph is
= f(x + 5) → B
Answer:
2120 mm
Step-by-step explanation:
→ Convert 2.12 metres into centimetres
2.12 × 100 = 212 cm
→ Multiply by 10 to get into mm
212 × 10 = 2120 mm
