If you have any questions about slope point formula...feel free to leave comments :)
Answer:
Rhombus
Step-by-step explanation:
The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).
We use the distance formula to find the length of AB.



The length of AD is



The length of BC is:



The length of CD is



Since all sides are congruent the quadrilateral could be a rhombus or a square.
Slope of AB
Slope of BC 
Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus
He will pay the 10% of $7200, and that is calculated like so:
(10%)(7200)
= (10/100)(7200)
= (1/10)(7200)
= 720
therefore he will pay $720
Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
Step-by-step explanation:
Since we have given that
Number of coffee drinkers = 10000
Number of whom developed anxiety = 500
Number of non coffee drinkers = 20000
Number of whom developed anxiety = 200
So, probability of getting anxiety from coffee drinkers = 
Probability of getting anxiety from non coffee drinkers = 
so, Relative risk of anxiety associated with coffee use is given by

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
