Answer:
Step-by-step explanation:
The answer is b.) (10x+1)^2
Answer: there is almost no relationship between x and y.
Explanation:
The coefficient r tells how well the data fix into the model chosen.
A value r = 1 indicates a perfect positive linear relation.
A value r = - 1 indicates a perfect negative linear relation.
Intermediates values may be interpreted more or less in this way:
1) 0.7 < |r| < 0.7 => strong relation between the variables
2) |r| ≈ 0.5 moderate relation between the variables
3) |r| ≈ 0.3 poor relation between the variables
4) |r| ≈ 0 non-relation between the variables.
Hey there!
The account earns 2.5% interest.
To figure out if it earns simple or compound interest, we need to figure out if the interest earned each year, simple, is the same amount or if it's increasing each year, compound.
512.50 - 500 = 12.50
525.31 - 512.50 = 12.81
538.44 - 525.31 = 13.13
Simple interest is based on the principal amount, so the amount earned each time is the same. But in compound interest, the interest previously earned is added before calculating the next period's interest, so the amount of interest earned each period is different.
So, this is a compound interest.
Hope this helps!
