A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.
B) It decelerates. The speed doesn't increase. It slows down.
C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.
D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.

thanks for 5 points
From the observation of the dispersion graph it is concluded that the answer to this question is option D. r = -0.5.
The correlation coefficient "r" is a measure of the linear relationship between two random variables.
When the correlation is positive, the value of "r" is between 0 and 1. This means that when one variable increases the other too.
When the correlation is negative, the value of "r" is between -1 and 0. This means that one variable decreases as the other increases.
When there is no correlation the value of "r" is 0
In this case, the dispersion chart shows that the variable "y" decreases as the variable "x" increases. Therefore the value of "r" must be negative. Of all the options, the only one that presents a value of negative r is option D:
r = -0.5
Answer:x = 4.25 - 3.87 x = 0.38 feet
Step-by-step explanation::Find out the how much string will Mellisa have left over .To proveLet us assume that the string will Mellisa have left over be x .As givenMelissa needs 3.87 feet of string to use as a border for her poster.Melissa finds a piece of string that is 4.25 feet long.Than the equation is write in the form. Therefore the string will Mellisa have left over be 0.38 feet .
