Answer:
attached above with detail explanation.
Answer:
x = -1
Step-by-step explanation:
1/2 = 2/4
____________________________________________________________
1/4x + 3/4 = 2/4
<u> -3/4 -3/4</u>
1/4x = -1/4
divide by -1/4
x = -1

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).
