A statistics student is studying if there is a relationship Using the computer output, what is the correlation? between the price of a used car and the number of

miles it had been driven. She collects data for 20 cars

0-0.82

of the same model with different mileage and

-0.68

determines each car's price using a used car website. 0.68

The analysis is given in the computer output.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
