The formula of a midpoint of the segment between the points

We have:

Substitute:

<h2>Answer:
B.</h2>
The method of least squares is a widely used method of fitting curve for a given data
Step-by-step explanation:
It is the most popular method used to determine the position of the trend line of a given time series. The trend line is technically called the best fit. ... The sum of the deviations of y from their corresponding trend values is zero.
Answer:
Model B
Step-by-step explanation:
First, solve what each model means:
Model A:
6 boxes, 2 shaded
2/6=1/3
1/3 is approximately 33.35
Model B:
8 boxes, 3 shaded
3/8 is 37.5%
this is the answer, but we can go ahead and check the other boxes
Model C:
5 boxes, 2 shaded
2/5 is 40%
Model D:
7 boxes, 3 shaded
3/7 is approximately 42.9%

Answer:
Step-by-step explanation:
Start with why C isn't the answer.
y = 1.8^0 . The power is zero. Anything to the zero power (anything except 0 to the 0 power) is 1. So 1.8^0 is 1 not something else. C assumes that somehow 0,1.8 turns into 1.8. It does not. The second part is also wrong but you don't need it. However here it is.
x = 0 y = 3
x = 1 y = 3 * 1.8 = 5.4
x = 2 y = 3 * 1.8^2 = 3*3.24 = 9.72
You should be able to see that if you multiply 5.4 by 3, you don't get 9.72
C just does not work.
=======
The actual answer is A. That's exactly what the graph does. If you multiply 5.4 * 1.8 you should get 9.72. Just for completeness, I've included the graph.
Answer:
32/21
Step-by-step explanation:
multiply (2/3) by (7/7) and (6/7) by (3/3). (14/21) + (18/21) is (32/21)
