Step-by-step explanation:
The standard equation of a circle is 
Center = (h, k)
#1
Center = (0,2)
h = 0
k = 2
r = 5


#2
Center = (-4,-5)
h = -4
k = -5
r = 



#3
Center =(-1,3)
h = -1
k = 3
r = 8



#4
Center: (9,0)
h = 9
k = 0
r =

Answer:
The Solution Set
Step-by-step explanation:
Despite missing some context, the output we could get as result of an expression/equation it is what we call a Solution set. A set which makes the initial statement of equation/expression true, therefore valid.

Therefore, the elements of the Solution set, 3 and 4 when plugged into the equation make the statement of the quadratic equation true.

Answer:
Find the smallest multiple the denominators have in common
30
Expand each fraction so that the denominators are 30

Add or subtract the numerators and keep the same denominator

Simplify

Probability is defined as the ratio of the successful
events over total events. In this case an event is described as the color of
block.
The total number of blocks present in the bag is:
total blocks = 36 + 48 + 22 + 19
total blocks = 125
So calculating for each theoretical probability:
P (green) = 48 / 125 = 0.384
P (not yellow) = P (red or green or purple)
P (not yellow) = (125 – 22) / 125 = 0.824
P (yellow or not green) = P (yellow or red or purple)
P (yellow or not green) = (125 – 48) / 125 = 0.616
