Answers

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?

Answers

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,

Answer:

Step-by-step explanation:

You do 5625 / 25 like this: For each step you multiply 25 by the highest number possible in the first 2 numbers. So if it was 27 / 9  you would find how many times 9 can fit into 27 but since the number 5625 is not one of the first 10 multiples of 25 you see the first 2 numbers and if you still can't divide you combine the next value. The top number is the answer.

2/5 divided by 3 in its simplest form in a fraction is?​

Answers

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

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).
