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:
Your friend is incorrect because if you divide 21 by 7 you will get 3 if you add 7 to 3 you get 10 therefore your friend is incorrect.
Answer:
11 in
Step-by-step explanation:
Area of a square is L^2
where L is length.
L^2 = 121 in^2
FIND THE SQUARE ROOT OF BOTH SIDES (including in^2).
L= 11 in.
side = 11 in
Please give brainliest, like, and rate 5 stars. I hope this helps. Thank you.
The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.
example 1
y = mx + b
m = slope b = y-intercept
y = 3x - 1
m = 3 and b = -1
example 2
y = b + m<em>x</em><em> </em>
b = y-intercept m = slope
y = 5 - 1/2x
m =- 1/2 and b = 5
