Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient ,
is greater than 0.
so,
≠ - 0.9
Also, there is a deviation from absolute linearity.
So,
≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence,
≠ 0.3 .
So
= 0.9
B) x=2 and y=14 i’m pretty sure lol
Answer:
22 inch is the diameter because d =2r
Answer:
(6, -3)
Step-by-step explanation:
The actual coordinates are x = -6 and y = 3
If we rotate 180 degrees and the center of rotation is at (0,0), all we need to do is invert the signal of each axis, that is, we invert the sign of the original x-coordinate and invert the signal of the original y-coordinate.
So the final x-coordinate is - (-6) = 6
And the final y-coordinate is - (3) = -3
So the coordinates will be (6, -3).
So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)
