What is the difference between the means of the numbers of birds per cage between the two shops?
OA. 21.8
ОВ.
16.2
OC. 5.6
OD. 2.8

72 is the answer to this problem

21/58.

hope to be marked brainliest

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
