The equation of the circle:

where:
(a; b) - coordinates of the center
r - a radius
Use:

We have:
Answer:The center: (-2; 4)The radius: r = 4
Answer:
(a) Option A. independent
(b) 
Step-by-step explanation:
Two events A and B are considered dependent if the occurrence of one affects the probability of occurrence of another.
In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.
In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.
When two events are independent then

The probability that a baby is a girl is

The probability of obtaining a 1 when casting a 16-sided die is:

Then:


E, 56, because you have 28 dollars, and you have to multiply that by two to get half dollars. 28*2=56.
5x- 10 = 20
5x -10 +10 = 20 +10
5x = 30
5x/5 =30/5
x = 6
