Answer and workings in the attachment below.
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).

Answer:
Step-by-step explanation:
twice a number .....multiplication
decreased by 4.....subtraction
divided by 8.....division
addition is missing <====
although, twice a number could also be addition.....but I have never used it for addition
lets say ur number is 4.......twice the number 4 could be : 2 * 4 or 4 + 4
