The table below shows britney's distance, in miles, from her destination after different time intervals in hours: time (hours) (x) 2 4 1 3 6 5 7 distance from destination (miles) (y) 1,000 880 1,060 940 760 820 690 what is the correlation coefficient for the data, and what does it represent? 0; it represents no correlation between x and y 0.999; it represents a linear positive correlation between x and y −0.999; it represents a linear negative correlation between x and y 0.999; it represents a linear negative correlation between x and y

It represents a linear positive correlation between x and y −0. 999.

Given

The table shows Britney's distance, in miles, from her destination after different time intervals in hours:

Time (hours) (x) 2 4 1 3 6 5 7

Distance from destination (miles) (y) 1,000 880 1,060 940 760 820 690

A number between +1 and −1 is calculated so as to represent the linear interdependence of two variables or sets of data.

Then,

The correlation coefficient for the data, and what does it represent is;

It represents no correlation between x and y.

Hence, it represents a linear positive correlation between x and y −0. 999.

r = -0.9997  

Step-by-step explanation:

A statistics calculator gives the value

r = -0.9997

You can see in the graph below that it represents an excellent negative correlation between x and y.

Every point appears to be exactly on the regression line .

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
