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
Answer:
Choice B
The mathematical model that best fits the data is a polynomial of order 2 as shown on the attachment.
The predicted global mean temperature in 2015 is; 412.24
Step-by-step explanation:
The first step is to obtain a scatter plot of the data and then fit a trend line. A quadratic polynomial fits the data well considering the large value of the coefficient of determination of 0.9984.
To determine the global mean temperature in 2015 we substitute x with 14 in the quadratic model;
y = 0.4643(14)^2 + 0.7976 (14) + 310.07
= 412.24
