Answer:
Mean: 3.2 Median: 3.2 Mode:3.1 Range:0.5
Step-by-step explanation:
Easy.
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
Answer:
Bottom left
Step-by-step explanation:
If you graph out the coordinates it goes in a perfect line, thus being linear.
