Answer: Choice B) negative linear association
=================================
Reasoning:
The points all go downhill as you move from left to right. We can draw a straight line that is fairly close to all of them. This is known as the regression line. The regression line having a negative slope tells us the linear association is negative. This means the correlation coefficient r is negative, so, (r = -1 is not possible as not all points fall on the same straight line)
Answer:
a. $1010.83
b.$1066.77
c. $1138.00
d.$13,269.22
Step-by-step explanation:
Given the annual rate as 13%(compounded monthly) and the principal amount as $1000.
a. #first we calculate the effective annual rate;
The compounded amount after 1 month is therefore:
Hence, the principle after one month is $1010.83
b. The principal after 6 months:
-From a above we have the effective annual rate as 0.1380 and our time is 6 months:
Hence, the principal after 6 months is $1066.77
c.The principal after 1 year:
-From a above we have the effective annual rate as 0.1380 and our time is 12 months:
Hence, the principal after 1 year is $1138.00
d. The principal after 20years:
-From a above we have the effective annual rate as 0.1380 and our time is 20yrs:
Hence, the principal after 20 years is $13,269.22
