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).

Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
The value of x is 3 given that ST = 8x + 11 and TU = 12x-1
The point that bisects a line divides the line into two equal parts
If T is the midpoint of SU, the following are true:
Given the following
ST = 8x + 11
TU = 12x-1
Since ST = TU
8x+11 = 12x-1
8x - 12x = -1 - 11
-4x = -12
x = 12/4
x = 3
Hence the value of x is 3 given that ST = 8x + 11 and TU = 12x-1
