8x-77 would be the answer to this
21, 45, 121, 300, 312, 333, 347, 421, 614,
The median is the middle number of a data set therefore you need to arrange the data is order from smallest to largest as I have done above. Then you need to find the number in the middle which is 312 in this case by finding the number which has the central position (position 5 in this case) of the data set. If there are an even number of numbers in the data set, you add them together and divide by 2 though that is not necessary this time as there are an odd number of numbers.
Answer:
Quadrant 4
Step-by-step explanation:
A) x -y =1
B) x * y =1
B) y = 1/x
A) x -(1/x) = 1
Multiplying both sides by "x"
A) x^2 -1 = x
A) x^2 -x -1 = 0
Solving by the quadratic formula
x = 1.618 and
y = .618
Interestingly, the number 1.6180339... is called the "phi ratio" or the "golden ratio".
