I think the correct answer from the choices listed above is the second option. The conclusion saying playing violin causes students to get better grades is a reasonable conclusion. This is because the correlation coefficient is above 0.5, so that implies causation. Hope this answers the question.
Answer:
20.33%
Step-by-step explanation:
Principal = $2650
Total Interest = $300
Total amount = 42650+$300=$2950
Since we are given that You paid off the loan in 1 year by making 12 monthly payments
So, monthly payment = 
Formula of monthly payment = 
where i is the rate of interest in decimals
To find i substitute the values

using calculator

So, rate of interest in percent = 
Thus the annual percentage rate (APR) is 20.33%
Answer:
Width = 7 inches
Length = 10 inches
Step-by-step explanation:
We know the 2(length + width) = 34, and we know that length = 3+width. Therefore, we can use substitution. 2(3+width+width) = 34, and we can see that the width is 7. The length of the rectangle is 7+3=10
You first multiply the coefficients to make 35. You then multiply the variables to make (gh). Therefore, the answer is 35gh
30 degrees due to the fact that all triangles interior angles add up to 180 degrees and there are two other angles meaning it is 30 degrees
