The interquartile range (IQR) is defined as the difference between the first and third quartiles (Q3−Q1). What feature of the box-and-whisker plot does the IQR describe?
Answer:
The interquartile range is also known as midspread and it is the between the first and third quartile (25th and 75th percentile respectively) serving as a robust measure of sample dispersion.
Interquartile range (IQR) = Q3 - Q1
As a measure of variability, it is based on splitting data sets into quartile (four equal portions). The values differentiating these portions are known as the first, second, and third quartile which are represented as Q1, Q2, and Q3, respectively.

The odds in favor of an event are 2:9 or 2/9. What are the odds against the event?
Answer:
Odds against the events are 7/9.
Step-by-step explanation:
It is given that:
Odds in favor of event = 2 : 9 or 2/9
Let,
These odds are out of 1.
The odds against the event would be
Odds against = 1 - 2/9
Odds against = [tex]\frac{9-2}{9}[/tex]
Odds against = [tex]\frac{7}{9}[/tex]
Therefore,
Odds against the events are 7/9.

2/5 divided by 3 in its simplest form in a fraction is?
Answer:
2/15
Step-by-step explanation:
Reduce the expression, if possible, by cancelling the common factors.
The equivalent value of the fraction is A = 2/15
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = p/q
when the value of p = 2/5
And , when the value of q = 3
On simplifying the equation , we get
A = ( 2/5 ) / 3
So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) / 3
A = ( 2/5 ) / 3
A = ( 2/5 ) ( 1/3 )
On simplifying , we get
A = 2/15
A = 0.133333
Therefore , the value of A = 2/15 = 0.133333
Hence , the fraction is A = 2/15

9c + 3 + 13c – 4c + 4 – 24c=?
Answer:
-6c + 7
Step-by-step explanation:
(This question probably requires bodmas)
9c + 3 = 9c + 3
9c + 3 + 13c = 22c + 3
22c + 3 - 4c = 18c + 3
18c + 3 + 4 = 18c + 7
18c + 7 - 24c = -6c + 7

Answer:
(3,9)
Step-by-step explanation:
9=9x-18
(Add 18 on both sides)
27=9x
(Divide both sides by 9)
3=x
The ordered pair in function f(x) corresponds to the equation will be (3, 9).
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The function is given below.
f(x) = 9x – 18
The value of the function is 9. Then the value of the variable 'x' is given as,
9 = 9x – 18
Simplify the equation, then we have
9 = 9x – 18
9x = 27
x = 3
The ordered pair in function f(x) corresponds to the equation will be (3, 9).

i. 10g3 27 ^3
Answer:
9
Step-by-step explanation:
Log₃27³
Recall that 27 = 3³
Hence
Log₃27³ = Log₃3³⁽³⁾ = Log₃3⁹
From the laws of logarithms, we know that
Logₐa = 1 and Log aˣ = xLog a
As such, applying both laws
Log₃3⁹ = 9Log₃3
since Log₃3 = 1
9Log₃3 = 9 * 1
= 9
