If the probability of an event happening is

1 answer:

4 0

If the probability of an event is P, the probability of that event NOT happening is equal to 1-P:

Example: if you roll a six-sided dye, what the probability of getting 4.

==> P(4) = 1/6 & the probability of NOT GETTING 4 is P(NOT 4) =5/6
I could have written 1- 1/6 & you'll notice that 1-1/6 =5/6

Determine the equation of the circle graphed below.

Bond [772]

Answer:

$(x+7)^2+(y-2)^2=4$

Step-by-step explanation:

The equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center of the circle and $r$ is the radius.

Since the center is $(h,k)\rightarrow(-7,2)$ , and the radius is $r=2$ , then the equation of the circle graphed is $(x-(-7))^2+(y-2)^2=2^2=(x+7)^2+(y-2)^2=4$ .
