The correct answer is the one on the left bottom. No matter what, if you subtract a value less than the amount ABOVE 1 in this situation, then you will always end up with more than 1.
Michael is 31 years old
John is 14 years old
31+14= 45
In 4 years the age will equal 49
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
The answer is $3,960
you multiply 220,000 by 0.03 to get the amount the broker takes which is $6,600
you then multiply 6,600 by 0.60 to get the amount the agent receives, being $3,960
