It's going to be going up. That means the answer is b.
Hope this helped☺☺
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
Answer:
£132
Step-by-step explanation:
15% of 520 is 78
15% of 360 is 54
78 + 54 = 132
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).
