The equation of a cirecle with radius r and center at (h,k) is
(x-h)^2+(y-k)^2=r^2
r=10
center=(-2,-4)
(x+2)^2+(y+4)^2=10^2
(x+2)^2+(y+4)^2=100
(x,y)
sub given points (or use TI) and see if you get a true statmeent
A is on it

answer is A

The equation of of circle = (x+2)^2 + (x+4)^2 = 100
by sub. by this points in the circle equation
for point V(8,-4)
(8+2)^2 + (-4+4)^2 = 100
so the point V lay on the circle

Randy is starting a beehive so that he can have fresh honey. He decides to check the current population of bees in the hive by m

satela [25.4K]

Answer:

Best estimate for the bee population is 1280.

Step-by-step explanation:

Randy marked total number of bees = 160

Then he collected 240 bees and observed that number of bees marked

= 30

We have to find the total population of the bee or best estimate for the bee population.

Now we use the ratio of marked bees in the sample vs marked bees in the total population

$\frac{\text{Number of bees marked in the sample}}{\text{Total bees in the sample taken}}=\frac{\text{Number of bees marked in total population}}{\text{Number of bees in the hive}}$ $\frac{30}{240}=\frac{160}{x}$
