A linear regression is a regression that can be represented by a linear line of best fit.
The equation of the line of best fit is
<h3>How to determine the equation</h3>
From the graph, we have the following ordered pairs
(x,y) = (50,150) and (100,270)
The slope (m) is then calculated as:
This gives
The regression line crosses the y-axis at b = 33.2
A linear regression is represented as:
y = mx + b
So, we have:
Hence, the equation of the line of best fit is

Answer:
-543
Step-by-step explanation:
For every value of k, you substitute 9 and for every value of c, you substitute 2
-6((8x(9)+ 9(2)) - 3
so order of operations says you should do what's in the parentheses first.
8 x 9= 72 and 9 x 2 = 18
so now you have -6 ( 72 + 18) -3
Finish the calculating inside the parentheses: -6 (90) -3
and now multiply -6 and 90 before you subtract 3
-6 x 90 = -540
-540 - 3 = -543
When solving for a variable, you want to get it isolated (i.e. alone). Here are the steps to do this equation...
1. Given: kx-3=5
2. Add three to both sides to remove the -3, and this gives you kx=8
3. Since the x is being multiplied by k, you want to do the inverse and divide both sides by k, and this gives you x=8/k
So this means that your answer is D

Answer:
Step-by-step explanation:
The given pattern is:
The first term is
The common ratio is the previous term of any consecutive two terms over the previous term.
The explicit formula that describes this pattern is:
We substitute the common ratio and the first term to get:
