Answer:
Table C
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality in each table
Table A
For ------>
For ------>
This table has different values of k
therefore
the table A does not represent a proportional relationship
Table B
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table B does not represent a proportional relationship
Table C
For ------>
For ------>
For ------>
For ------>
This table has the same value of k
therefore
the table C represent a proportional relationship
Table D
For ------>
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table D does not represent a proportional relationship
90 < [( n + n + 2 + n + 4) / 2] < 105
90 < (3n + 6) / 2 < 105
3n + 6 > 180 and 3n + 6 < 210
n > 58 , n < 68
58 < n < 68 answer
