Which of the following represents "the average of 171 and x"?

(x + 2)/171
(171 + x)/2
(171 - x)/2

Step-by-step explanation:

We know that the average of any n observations is given by :-

The given observations : x and 171

Sum of observations :

Number of observations : 2

Now, the average of 171 and x is given by :-

Hence, the expression represents the average of 171 and x is .

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|
