The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).
<h3>What is a regression line?</h3>
A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.
According to the given problem,
From the table we can see,
ln(Element) is the dependent variable and Time is the independent variable.
The constant = 2.305,
Time = -0.101
Hence, we can conclude, our least squared regression line will be
In (Element) = 2.305 - 0.101 (Time).

Step-by-step explanation:
Answer:
236.55 (Rounded to two decimal places)
Step-by-step explanation:
Area of the rectangle:
12 x 15 = 180
Area of semicircle:
π6^2/2 = 56.54866776...
Total area:
180 + 56.54866776...
= 236.55
