Answer:
A) Negative Correlation. B) C. C) B
Step-by-step explanation:
<h2>A:</h2>
As the line of best fit is travelling downwards, it is a negative correlation, if the line of best fit is travelling upwards, it is a positive correlation, if the points on the graph are all over the place, there is no correlation.
<h2>B:</h2>
As there are only three types of correlation, the strongest is always the positive.
<h2>C:</h2>
The answer is B because there is no correlation and that means that there shouldn't be a line of best fit.
Answer:
A.) (x + 2) and (2x - 1)
Step-by-step explanation:
So from the video i just watch this is how its done
3 (2x^2 + 3x - 2) = 0
4 and -1 gives you 3 and you divide them by a which is 2
4/2 (2/1) and -1/2 then you write them from the bottom to top
(x + 2) and (2x - 1)
Answer:
B.) 20 (x + 5) (x - 5) = 0
Step-by-step explanation:
20 (x^2 - 25) = 0
20 (x + 5) (x - 5) = 0
EZ
Answer:
i think its d
Step-by-step explanation:
it takes away 2 from the negative. number.....and negative 5 is still greater...sorry if its wrong
The line y=1 is the horizontal line passing through the point (0, 1). We have drawn it with red.
The reflection across this line of each point X, Y, and Z is such that the distance of each X, Y, and Z is equal to the distance of each X', Y', and Z', respectively, to the red line.
According to our drawing, we see that the coordinates of X' are (3, 3).
