Answer:
Table B
Step-by-step explanation:
If a table is to represent a function, it cannot have any repeated input values.
Table A repeats the input value 5.
Table C repeats the input value 1.
Table D repeats the input value 4.
Table B represents a function.
2 should be the correct answer!
First number = X
Second number = 8X
Third number = X - 3
The equation would be
X + (8X) + (X - 3) = 207
X + (8X) + (X - 3) = 207
X + 8X + X - 3 = 207
10X - 3 = 207
10X = 207 + 3
10X = 210
X = 21
First number = 21
Second number = 8 * 21 = 168
Third number = 21 - 3 = 18
Median would be 8.. not sure about the mode though considering there are no repeating numbers..
