Answer:

Option D is correct.

$\lfloor 4.8 \rfloor$ and
$\lceil 3.2 \rceil$

Explanation:

Floor function states that the greatest integer that is less than or equal to x.

It is represented by:
$\lfloor x \rfloor$

Ceiling function states that the least integer that is greater than or equal to x.

It is represented by:
$\lceil x \rceil$

As per the statement:-

Kareem wrote the values show below:

$\lceil 3.2 \rceil$ ,
$\lfloor 2.7 \rfloor$ ,
$\lceil 2.9 \rceil$ and
$\lfloor 4.8 \rfloor$ .

by definition:

$\lceil 3.2 \rceil$ = 4

$\lfloor 2.7 \rfloor$ = 2

$\lceil 2.9 \rceil$ =3

$\lfloor 4.8 \rfloor$ = 4

From the given options only pair which is equivalent is:

$\lfloor 4.8 \rfloor$ and
$\lceil 3.2 \rceil$
