The given diagram is a scatter plot in which temperature is plotted against number of visitors.
As the number of visitors is rising with the rise in temperature, its a positive correlation.
As joining the dots is going to give a web of line segments, it is not going to be helpful to understand the trends.
The best way to understand the trends is to make the line of best Fit in such a way that the number of dots on either side are approximately the same.
I have attached the figure for your reference of the line of best fit.
Answer:
(x-1)^2 + y^2 = 25
Step-by-step explanation:
center C ( ( xA + xB)/2 , (yA+yB)/2 ) = ( 1 , 0)
AB = 10
radius = AB / 2 = 5
equation formula: (x - xC)^2 + (y-yC)^2 = radius^2
Hence:
(x-1)^2 + y^2 = 25
Hello!
Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.
I can see here that this can be divided into a triangle and a rectangle using a horizontal line.
The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.
This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.
Which is in simplest radical form.
Hope this helps!
When a graph is drawn with output on the vertical axis and input on the horizontal axis, this indicates that the straight or "flat" segment on the graph is the representation of a region where the output doesn't change in response to the input.
In an equation using x is just a place holder because those numbers are variables so it doesn't matter whether it is x or w.
