Step-by-step explanation:
A correlation coefficient describes the relationship between two variables. A zero shows that there is no correlation while a one describes a positive correlation. A negative one describes a negative correlation. Since all of the dot in the scatter plot in figure 2 are spread out and not in a line, it has no correlation or you could say that it's coefficient is zero. Since the dots in figure 1 are going from left to right and are close together, it has a positive correlation. Since the dots in figure three are going right to left and resemble a line, the correlation coefficient is -1.
I think the answer would be 31°
Answer:
H
Step-by-step explanation:
-4000 is the slope
pick a point
y = -4000x + 20000
40/60=60/x...forty miles in sixty minutes is equal to 60 miles in 40 minutes.....40x=3600....x=90..90 minutes
