Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as
then the equation relating them is
c = k
← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75
← equation of variation
When d = 324 , then
c = 1.75 ×
= 1.75 × 18 = 31.5
I think it’s a very weak association because a strong one would be forming a straight line but this is clustered in one area. It’s not a no correlation because it’s not just anywhere
